Brain Physiology - Neurotransmitters
An MD focusing on nervous system disorders, Dr. Robert Buchanan delivers a high professional standard of psychiatric and neurosurgical care at his Austin, Texas, private practice affiliated with the Seton Brain & Spine Institute. Over his career as neurosurgeon, Robert Buchanan, MD has performed funded research on methods of neurotransmitter measurement.
Biology: Nervous System 1
Psychologists study the brain and nervous system to understand how biological functions influence human behavior. The nervous system contains around 1 trillion nerve cells and 100 chemicals called neurotransmitters that transmit messages between nerves. An excess or lack of certain neurotransmitters like dopamine, serotonin, and endorphins can impact behaviors related to movement, mood, reward processing, pain, and mental illnesses. Understanding the biological underpinnings of behavior provides psychologists with insights to treat conditions influenced by neurotransmitter imbalances.
Neurotransmitters
Neurotransmitters are chemicals that neurons release to communicate with each other at synapses. There are over 100 types of neurotransmitters but about 10 are responsible for most brain activity. The major neurotransmitters are dopamine, acetylcholine, GABA, norepinephrine, serotonin, and oxytocin. They can be either excitatory, making actions happen, or inhibitory, stopping actions from happening. Imbalances in neurotransmitters are associated with various mental and neurological disorders.
Drugs and effects on neurotransmitters
This document discusses how various drugs work by altering neurotransmitters in the brain. It explains that drugs can increase or decrease neurotransmitter production, transport, storage, release, or receptor binding. It then provides details on specific drugs like caffeine, nicotine, alcohol, cannabis, meth/cocaine, heroin, LSD/peyote/mushrooms, and MDMA, describing which neurotransmitters they affect and how this leads to their psychoactive effects as well as risks of addiction and withdrawal.
The nervous and endocrine system
The document discusses the nervous and endocrine systems and their roles in exercise. The nervous system has two main parts - the central nervous system consisting of the brain and spinal cord, and the peripheral nervous system which communicates with the CNS. Regular activity can enhance connections between nerves and muscles and improve strength over time. The endocrine system includes glands like the pancreas and adrenals that release hormones like insulin, adrenaline, and testosterone to prepare and support the body during exercise.
Neurotransmitters
Neurotransmitters are chemicals located and released in the brain that allow communication between neurons. They gather in the space between neurons called the synapse and act on receptors on the receiving neuron. Some key neurotransmitters include acetylcholine, which triggers muscle contraction and is involved in wakefulness; dopamine, which controls movement and modulates mood; GABA, which regulates anxiety; and glutamate, which is associated with learning and memory. Scientists have identified over 60 molecules that meet the criteria to be considered neurotransmitters.
The nervous system
The document summarizes the key aspects of the human nervous system. It describes how the nervous system and endocrine system both play a role in homeostasis through secreting chemical messages, though the nervous system is much faster. It defines the main cell type, neurons, and describes the three types - sensory, inter, and motor neurons. It also outlines the main components of the central nervous system, including the brain and spinal cord, and the peripheral nervous system. Finally, it briefly discusses some common malfunctions of the nervous system like cerebral palsy, meningitis, stroke, and polio.
Endocrine and Nervous System IHS Unit 4
The document discusses the nervous and endocrine systems. The nervous system includes billions of neurons and is divided into the central nervous system (brain and spinal cord) and peripheral nervous system. The brain acts as the central control center and uses electrical impulses and neurotransmitters to communicate. The endocrine system is made up of hormone-producing glands that regulate body functions through chemicals called hormones, which are released into the bloodstream. The pituitary gland controls many other glands. The nervous and endocrine systems work together to control the body, with the nervous system reacting fast to changes and the endocrine system responding more slowly.

Nervous system
The nervous system is responsible for all behavior, thoughts, and actions in the body. It works with the endocrine system to maintain homeostasis. The nervous system has three main functions - sensory input, integration of information, and motor output responses. It is divided into the central nervous system (brain and spinal cord) and peripheral nervous system, with the peripheral system further divided into afferent and efferent divisions. Neurons are the basic structural and functional units of the nervous system and come in various types like multipolar neurons. Glial cells provide support and protection for neurons in the central and peripheral nervous systems. Certain drugs can artificially stimulate the brain's pleasure centers and rewire how neurotransmitters function, leading to addiction
Autonomic physiology and pharmacology 1 2017 18 jap
This is a 23 slide presentation introducing the key facts about the autonomic nervous system (ANS), It is suitable for intermediate level learners.
Endocrine and nervous system
The endocrine system is comprised of glands that secrete hormones into the bloodstream to regulate various bodily functions like growth, stress response, and metabolism. The key glands include the pineal gland, hypothalamus, thyroid, parathyroid, pituitary gland, adrenal glands, pancreas, ovaries, and testes. The hypothalamus connects the endocrine and nervous systems by secreting neurohormones that stimulate or inhibit hormones from the pituitary gland, which then regulate other glands. Hormones and the nervous system interact through feedback and effects on neural processing and development.
Neurotransmitters2
Neurotransmitters are chemicals that allow communication between neurons by being released at the synapse, the space between neurons. Some key excitatory neurotransmitters include acetylcholine, which triggers muscle contraction and hormone release and is involved in wakefulness, and glutamate, which is associated with learning and memory. Important inhibitory neurotransmitters are GABA, which contributes to motor control and regulates anxiety, and dopamine, which controls movement and modulates mood. Serotonin and norepinephrine also play roles in various functions like mood, sleep, and appetite.
IGCSE biology chapter 13- the nervous system
The document summarizes key concepts about the human nervous system:
1. The nervous system consists of the central nervous system (brain and spinal cord) and peripheral nervous system (cranial and spinal nerves). The brain controls voluntary actions while the spinal cord controls involuntary reflexes.
2. Sensory neurons detect stimuli and transmit nerve impulses to the central nervous system, while motor neurons transmit impulses from the CNS to effectors like muscles.
3. A reflex arc involves a receptor, sensory neuron, relay neuron, motor neuron, and effector to produce an involuntary response like the knee jerk reflex.
AnaPhy | Parasympathetic and Sympathetic Division
The document discusses the autonomic nervous system, which consists of the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is activated during stressful situations and produces the fight-or-flight response by increasing heart rate, blood pressure, and metabolism. In contrast, the parasympathetic nervous system activates during rest and digestion and works to conserve energy by slowing the heart rate and increasing digestion. Both systems work in opposition to regulate organ function during stress and relaxation.
Neurotransmitters
This document summarizes key aspects of neurotransmission. It defines neurotransmitters as chemical messengers that carry signals between neurons to control bodily functions. Neurons communicate at synapses by releasing neurotransmitters into the synaptic cleft between the presynaptic and postsynaptic membranes. Neurotransmitters are either excitatory or inhibitory, with excitatory neurotransmitters triggering signals and inhibitory neurotransmitters blocking signals. Specific neurotransmitters discussed include serotonin, GABA, glutamate, dopamine, norepinephrine, epinephrine, histamine, and endorphins. Their roles and impacts on mood, behavior, learning, and other functions are described.
Introduction to autonomic pharmacology
The document summarizes the structure and function of the nervous system. It describes how the nervous system is divided into the central nervous system (CNS) and peripheral nervous system. The peripheral nervous system is further divided into the efferent and afferent divisions. The efferent division carries signals from the CNS to peripheral tissues and is divided into the somatic and autonomic systems. The autonomic system regulates vital functions unconsciously through the neurotransmitters acetylcholine and norepinephrine. Acetylcholine and norepinephrine are synthesized, stored, released, and terminated through specific mechanisms to control organs and physiological processes.
Ans(organization , subdivision and innervations)
The document discusses the organization and function of the autonomic nervous system (ANS). The ANS regulates organs automatically and unconsciously. It has two divisions - the sympathetic and parasympathetic nervous systems. The sympathetic system is active during fight or flight responses while the parasympathetic system acts during rest and digestion. Most organs receive input from both divisions, allowing for cooperative or opposing effects. The ANS maintains homeostasis through its control of various body systems.
Neurotransmitters
Neurotransmitters are chemical messengers that transmit signals between neurons. There are four main neurotransmitter systems: monoamines like dopamine and serotonin which regulate movement, mood, and reward; acetylcholine which is involved in memory, attention, and muscle control; amino acids like glutamate and GABA which are excitatory or inhibitory; and neuropeptides which modulate various functions. Disorders like Parkinson's, Alzheimer's, epilepsy, depression, and others have been linked to imbalances in specific neurotransmitters.
COGS 107B - Winter 2010 - Lecture 9 - Neuromodulators and Drugs of Abuse
The document discusses neuromodulators and their role in the brain and association with drugs of abuse. It notes that neuromodulators like acetylcholine, serotonin, and dopamine are released by small groups of neurons and project widely in the brain to alter responses. Drugs of abuse are often associated with these neuromodulatory systems. The document also discusses how neuromodulators can alter ion channel properties and neuronal responses through phosphorylation, as well as their uneven distribution across dendrites leading to changes in response to different inputs.
Neurons & hormonal systems
Neurons are the basic units of the nervous system that transmit electrical and chemical signals. When an electrical signal reaches the end of an axon, it causes neurotransmitters to be released into synapses, which then stimulate or inhibit neighboring neurons. The nervous system is divided into the central nervous system, containing the brain and spinal cord, and the peripheral nervous system, containing nerves that connect to muscles and organs. The endocrine system communicates through hormones released by glands into the bloodstream to influence distant tissues like the brain.
Coordination and response
This document discusses coordination and response in organisms. It describes how organisms detect changes in their external and internal environments using receptors, and respond through neural and endocrine pathways. The nervous system plays a key role in coordination, with the central nervous system processing sensory information and initiating responses via the peripheral nervous system. This allows organisms to maintain stable internal conditions while living in a changing external environment.
Chapter 17
The nervous system forms a communication network throughout the body. It has two main divisions: the central nervous system (CNS) consisting of the brain and spinal cord, and the peripheral nervous system (PNS) made up of nerves. Neurons are specialized to carry electrical signals and come in three types - sensory, inter and motor. The brain is the control center and is divided into the cerebrum, diencephalon, cerebellum and brain stem. Diseases like Alzheimer's, Parkinson's, strokes and meningitis can affect the brain.
Neurotransmitters and their functions
Neurotransmitters are chemical messengers that transmit signals between neurons. They are produced in neuron cell bodies, stored in vesicles, and released into the synaptic cleft upon neuronal stimulation. Common neurotransmitters include acetylcholine, dopamine, norepinephrine, serotonin, GABA, glutamate, and endorphins. Neurotransmitters play important roles in functions like movement, cognition, mood, sleep, and pain perception. Imbalances can result in conditions such as depression, anxiety, Parkinson's disease, and Alzheimer's disease.
A&p 17 receptors and signaling of the ans
The document discusses the physiology of the autonomic nervous system, including its anatomy and receptors. It describes the two main divisions - the parasympathetic and sympathetic nervous systems. The parasympathetic system uses acetylcholine and muscarinic receptors to generally slow the heart and digestive processes. The sympathetic system uses norepinephrine and adrenergic receptors to activate the fight or flight response through increased heart rate, blood pressure and metabolism.

Coordination & Response Part 1 - The Nervous System
The document provides information about the coordination and response system in biology. It discusses the following key points:
- Living organisms respond to stimuli in their internal and external environments through coordination between different body systems. The nervous and endocrine systems play major roles in coordination.
- Stimuli are changes in the environment that are detected by sensory receptors and elicit responses. There are internal and external stimuli.
- The nervous system detects stimuli and coordinates responses. It has three main parts: sensory receptors, an integrating center (brain and spinal cord), and effectors.
- The central nervous system includes the brain and spinal cord. The brain is divided into different regions that control various functions like movement, sensation, thinking,
Chapter 08: Movement
The document discusses several topics related to brain mechanisms of movement:
1) The primary motor cortex and areas near it such as the premotor cortex and supplementary motor cortex are involved in controlling movement, with the primary motor cortex sending axons to the basal ganglia and brainstem/spinal cord.
2) The cerebellum plays an important role in motor control and learned motor behaviors through connections with other parts of the brain and spinal cord.
3) Basal ganglia structures like the caudate nucleus, putamen, and globus pallidus are important for habit learning and movement selection, and disorders like Parkinson's and Huntington's disease impact these areas.
Neurotransmitters dr. jawad class of 2015

It describes the biochemical pathways for neurotransmitter synthesis and degradation and identifies some clinical disorders that can arise from disrupted neurotransmitter metabolism.
Homeostatic imbalance muscles
This document discusses various homeostatic imbalances that can affect the muscular system. It begins by explaining how healthcare providers must determine if mobility issues are caused by joint, neurological, or muscular problems. It then defines and provides details on several specific muscular conditions: muscle atrophy (wasting), strain, dystonia, hernia, tetanus, muscular dystrophy, and myasthenia gravis. The document concludes by mentioning traumatic muscle injuries from overuse or accidents that athletes commonly experience.
Models of Disability: A Puzzle in Five Pieces
This document discusses four models of disability: the Charity Model, Medical Model, Social Model, and Economic Model. [1] Each model provides a different framework for understanding disability but also has limitations when viewed in isolation. [2] The Social Model, which was developed by the disability community, focuses on societal barriers rather than individual limitations. [3] Fully realizing the ideals of these models requires addressing their interdependence and drawing from the perspectives of other models.

Peter Crampton on public health in New Zealand
Prof Peter Crampton (Dean and Head of Campus, University of Otago Wellington)
specialist in public health medicine, argues that public health is a social, political, economic and justice issue, not a medical one. After charting the course of change to our health system since the 30’s, he urges every citizen to articulate in all their relationships (personal, professional, civil), their commitment to public health as a right of citizenship. He also agues that the goal of the public health system is to reduce inequalities and produce just outcomes for all New Zealanders.

eHealth and Patient Safety
The document discusses challenges with e-health and patient safety in New Zealand. It notes that patients want appropriate, safe, private care with good information and convenience, but often receive records that are disorganized and not integrated between providers. The document presents four cases: 1) a patient receiving suboptimal primary care despite quality standards, 2) a doctor failing to properly notify a patient of test results, 3) a medication error where an elderly patient received another's morphine in the hospital, and 4) a hospital failing to send a discharge summary to a patient's GP after multiple admissions. Overall it finds that while standards and accreditation aim to ensure quality, more work is still needed to translate this into good patient care in practice

The document discusses several key concepts related to how drugs work in the body including:
- Intended effects are the reasons for using a drug while unintended effects are side effects. Common side effects include nausea, changes in alertness, and dependence.
- A drug's effects depend on factors like dose, tolerance, potency, route of administration, rate of absorption, distribution and metabolism. Higher doses can produce therapeutic or toxic effects.
- Drug interactions can be additive, antagonistic, or synergistic. Pharmacokinetic factors like metabolism and elimination influence drug effects.

CNS depressants like benzodiazepines and barbiturates are commonly prescribed but can cause problems if not properly monitored. Their use began in the 1800s with bromides and was later replaced by barbiturates and then benzodiazepines. While relatively safe in short term use, long term use of benzodiazepines can lead to dependence and withdrawal problems. CNS depressants work by reducing brain activity and awareness through effects on the neurotransmitter GABA. They are classified based on their effects from sedatives to hypnotics to anesthetics depending on dose.

Unit 5 interaction
The document compares and contrasts the nervous system and endocrine system. The nervous system uses nerves and nerve impulses to transmit signals quickly over short distances to coordinate rapid responses. In contrast, the endocrine system uses hormones released into the bloodstream to transmit signals slowly over long distances to regulate functions requiring sustained responses like growth and metabolism. The document then provides details on the structure and function of the nervous system, including its central and peripheral divisions, neurons, synapses, and the roles of the brain and spinal cord.
nervous system
The document discusses the nervous system, including its key components and functions. It describes:
- The central nervous system (CNS), made up of the brain and spinal cord, and the peripheral nervous system (PNS), consisting of nerves that connect to organs.
- How neurons transmit signals via electrical and chemical synapses, aided by glial cells. The PNS has somatic and autonomic divisions, with the latter regulating involuntary functions.
- Common nervous system disorders include infections, injuries, degeneration and functional issues presenting with headaches, weakness and sensory changes. Neurologists and neurological surgeons treat such conditions.
PPT on Nervous System
The document discusses the nervous system, which controls and coordinates the body. It describes the central nervous system, made up of the brain and spinal cord, and the peripheral nervous system. The nervous system is classified into the somatic system for voluntary movement, and the autonomic system with the sympathetic and parasympathetic divisions for involuntary functions like digestion. Neurons are the basic functional units that receive, integrate, and transmit information via chemical signals. There are sensory neurons, motor neurons, and mixed neurons. Neurotransmitters are the chemical signals that convey information between neurons in the brain and spinal cord.

It discusses the cellular components, organization, and divisions of the nervous system including the central nervous system and peripheral nervous system. Key topics covered include neurons, nerve tissue, the brain and spinal cord, reflex action, communication between neurons, graded potentials, action potentials, and homeostasis. The summary focuses on the essential information about the structure and function of the nervous system.
Unit 5 Nervous and endocrine systems
The nervous and endocrine systems work together to regulate and coordinate the body's interactions with the environment and maintain homeostasis. The nervous system uses electrical signals conducted through neurons to transmit information quickly. The endocrine system uses hormones secreted by glands to regulate processes more slowly. Disruptions to these systems can cause diseases like Alzheimer's, diabetes, bulimia/anorexia, hypothyroidism, epilepsy, and gigantism.
Psych 200 Neuroscience and Behavior
Neurons are the basic building blocks and signaling cells of the nervous system. They have a cell body containing the nucleus, dendrites which receive signals, and an axon which carries signals to other cells. Neurons communicate via electrochemical signals and neurotransmitters released at synapses between neurons. The nervous system is divided into the central nervous system (brain and spinal cord) and peripheral nervous system. The peripheral system includes the somatic and autonomic systems. The autonomic system regulates involuntary functions and has sympathetic and parasympathetic divisions. The brain is the control center and can be studied using techniques like EEG, CAT scans, PET scans, and MRI. It is made up of the hindbrain, midbrain,

Tools for studying the nervous system like EEG, MRI, and PET scans are also summarized. The relationship between genetics, genes, and behavior is briefly covered. The endocrine and autonomic nervous systems are defined and compared.
Unit 29 Endocrine System
The nervous system and endocrine system communicate between organ systems to maintain homeostasis. The nervous system works quickly using electrical and chemical signals, while the endocrine system works more slowly using chemical signals through the bloodstream. Neurons are specialized cells that receive and transmit electrochemical signals through their dendrites, cell body, and axon. The senses detect internal and external stimuli which are transmitted by the nervous system. The central nervous system interprets this information and communicates with the peripheral nervous system to stimulate responses. The endocrine system produces hormones that influence cells and affect growth, development, and other processes through chemical messengers in the bloodstream.
Nervous System
The nerve cell is the basic unit of communication in the vertebrate nervous system. A neuron consists of a cell body with dendrites that receive signals and a long axon that transmits impulses. An action potential is generated when the voltage across the membrane is briefly switched and moves down the axon. Neurotransmitters are released at the synaptic cleft between neurons to transmit signals to the next cell. The nervous system is divided into the central nervous system (brain and spinal cord) and peripheral nervous system. Sensory neurons carry signals to the CNS while motor neurons carry signals away from the CNS to effector cells like muscles.
Chapter 4 Homeostatic Systems and Drugs
This document provides information on homeostatic systems and drugs. It discusses the nervous system and endocrine system, which work together to maintain homeostasis. The nervous system uses neurons and neurotransmitters like dopamine, GABA, and serotonin to send messages. These neurotransmitters can be affected by drugs. The document also describes the central nervous system, peripheral nervous system, and autonomic nervous system. The endocrine system maintains homeostasis through hormone secretion into the bloodstream. Anabolic steroids, which are sometimes abused, work to increase muscle mass.

We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Recently uploaded (20)
