The human brain
The human brain is the most complex organ in the body. It is made up of the cerebrum, cerebellum, and brain stem. The cerebrum is divided into four lobes - frontal, parietal, temporal, and occipital - each responsible for different functions like planning, sensation, memory, and vision. Within the cerebrum lies the limbic system which regulates emotion and memory. The brain stem connects the brain to the spinal cord and controls involuntary actions. The cerebellum coordinates movement and balance. Specific areas of the brain are associated with vision, language, emotion, memory, and other cognitive and motor functions.
Nervous system
The nervous system has two main parts - the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, and acts as the main control center. The brain controls all body functions and processes sensory information. The spinal cord relays messages between the brain and body and coordinates reflexes. The PNS connects the CNS to the rest of the body using cranial and spinal nerves. It links the CNS to sensory receptors and muscles throughout the body.

Spinal cord
The spinal cord extends from the skull to the lumbar vertebrae and contains gray matter in an H-shaped arrangement. It provides bidirectional communication between the brain and body via ascending and descending tracts. The spinal cord is protected within vertebrae and surrounded by meninges including the dura, arachnoid, and pia mater.
The Brain
The brain is one of the most complex organs in the human body. It controls muscle movements, gland secretions, breathing, temperature regulation and processes sensory data. The brain and spinal cord begin as an embryonic structure called the neural tube which forms the three primary brain vesicles - forebrain, midbrain and hindbrain. These vesicles further differentiate into the adult brain structures. The major components of the adult brain are the cerebrum, cerebellum and brainstem. The cerebrum contains lobes, gyri, sulci and ventricles. It also contains white matter, basal ganglia and diencephalon structures like the thalamus.

In most of the vertebrates the brain is at the front, in the head. It is protected by the skull and close to the main sense organs.
Brains are extremely complex and the part of human and animal body. The brain controls the other organs of the body, either by activating muscles or by causing secretion of chemicals such as hormones and neurotransmitters.
Muscular action allows rapid and coordinated responses to changes in the environment.
The brain of an adult human weights about 1300–1400 grams .
In vertebrates, the spinal cord by itself can cause reflex responses as well as simple movement such as swimming or walking. However, sophisticated control of behaviour requires a centralized brain.
The structure of all vertebrate brains is basically the same.
At the same time, during the course of evolution, the vertebrate brain has undergone changes, and become more effective.
In so-called 'lower' animals, most or all of the brain structure is inherited, and therefore their behaviour is mostly instinctive.
In mammals, and especially in man, the brain is developed further during life by learning. This has the benefit of helping them fit better into their environment. The capacity to learn is seen best in the cerebral cortex.
Three principles
The brain and nervous system is essentially a system which makes connections. It has input from sense organs and output to muscles. It is connected in several ways with the endocrine system, which makes hormones, and the digestive system and sex system. Hormones work slowly, so those changes are gradual.
The brain is a kind of department store. It has, all inter-connected, departments which do different things. They all help each other gather senses.
Much of what the body does is not conscious. Basically, much of the body runs on automatic (breathing, heart beat, hungry, hair growth) adjusted by the autonomic nervous system. The brain, too, does much of its work without a person noticing it. The unconscious mind refers to the brain activities which are hardly ever noticed.
The human brain.pptx
The document discusses the anatomy and physiology of the brain. It describes the main parts of the brain as the cerebrum, cerebellum, and brain stem. The cerebrum is the largest part and is divided into four lobes that control functions like movement, sensation, vision, and language. The cerebellum aids in movement coordination and balance. The brain stem consists of the midbrain, pons, and medulla, and controls vital functions like breathing and heart rate. Other parts discussed include the thalamus and hypothalamus, which regulate sensation and autonomic body processes respectively.
3 central nervous system brain
The central nervous system is comprised of the brain and spinal cord. The brain controls bodily functions like awareness, movement, and memory. The spinal cord transmits sensory and motor signals through the spinal canal. The brain is protected by meninges and cerebrospinal fluid. It can be divided into the hindbrain, midbrain, and forebrain. The forebrain contains structures that regulate homeostasis, memory, emotion, and higher cognitive functions.
NEUROTRANSMITTERS.pptx
This slide talks about neuroplasticity, the central nervous system, the brain and its structure, the spinal cord, autonomic nervous system, its functions, nervous system and learning, neurotransmitters, working of neurotransmitters, classification, types of neurotransmitters, neurotransmitters in learning and limbic system in learning.
CNS.ppt
The document summarizes the main parts and functions of the human nervous system. It is divided into three main parts: the forebrain, midbrain, and hindbrain. The forebrain includes the cerebrum, thalamus, and hypothalamus and is associated with higher functions like thought and action. The midbrain includes the tectum and tegmentum and is involved in vision, hearing, eye movement, and body movement. The hindbrain includes the cerebellum, pons, and medulla. It controls functions like balance, motor control, sensory analysis, breathing, heart rate, consciousness, sleep, and movement.

The central nervous system (CNS) consists of the brain and spinal cord. The brain is protected by membranes, bones, and cerebrospinal fluid. It contains neurons and is divided into the forebrain, midbrain, and hindbrain. The forebrain controls functions like emotions and memory. The spinal cord extends from the brain down the back and connects to all parts of the body, controlling movement and carrying sensory information. It is divided into cervical, thoracic, and lumbar regions.

The Ultimate Guide in Setting Up Market Research System in Health-Tech
How to effectively start market research in the health tech industry by defining objectives, crafting problem statements, selecting methods, identifying data collection sources, and setting clear timelines. This guide covers all the preliminary steps needed to lay a strong foundation for your research.
"Market Research it too text-booky, I am in the market for a decade, I am living research book" this is what the founder I met on the event claimed, few of my colleagues rolled their eyes. Its true that one cannot over look the real life experience, but one cannot out beat structured gold mine of market research.
Many 0 to 1 startup founders often overlook market research, but this critical step can make or break a venture, especially in health tech.
But Why do they skip it?
Limited resources—time, money, and manpower—are common culprits.
"In fact, a survey by CB Insights found that 42% of startups fail due to no market need, which is like building a spaceship to Mars only to realise you forgot the fuel."
Sudharsan Srinivasan
Operational Partner Pitchworks VC Studio
Overconfidence in their product’s success leads founders to assume it will naturally find its market, especially in health tech where patient needs, entire system issues and regulatory requirements are as complex as trying to perform brain surgery with a butter knife. Additionally, the pressure to launch quickly and the belief in their own intuition further contribute to this oversight. Yet, thorough market research in health tech could be the key to transforming a startup's vision into a life-saving reality, instead of a medical mishap waiting to happen.
Example of Market Research working
Innovaccer, founded by Abhinav Shashank in 2014, focuses on improving healthcare delivery through data-driven insights and interoperability solutions. Before launching their platform, Innovaccer conducted extensive market research to understand the challenges faced by healthcare organizations and the potential for innovation in healthcare IT.

- 2. Brain Cerebrum Cerebral cortex Corpus collosum Cerebellum Diencephalon thalamus Pineal body hypothalamus Brain stem Mid brain Pons Medulla oblongata
- 3. The frontal lobe - The frontal lobe is located at the front of the brain. It has a huge role in what we do and who we are, and controls our personality, emotions, memory and behavior The parietal lobe -The parietal lobe sits directly behind the frontal lobe at the top of the brain. It consists of two areas: the ‘sensory cortex’, which receives information from our senses, such as touch, pain and pressure; and the ‘motor cortex’, which helps control how we move our limbs and body in the space we are in. It is, therefore, involved with spatial awareness The temporal lobe -The temporal lobe is located at the middle, lower half of the brain. It is a complex part of the brain, which is involved in many ‘higher’ functions, such as intellect and behavior. The temporal lobe has a large role in auditory perception (hearing) and is important in processing the meaning of speech. Occipital lobe – The occipital lobe is the smallest of the four lobes. Although it is located towards the very rear of the skull, it is still technically classed as part of the forebrain. The primary role of the occipital lobe is the control of vision BRAIN ANATOMY The brain is made up of around 100 billion nerve cells It weights around 1.3-1.5 kg Present within the Cranium of the skull The cerebrum is the largest part of the brain. The two hemispheres, the left and right, are joined together by a bundle of nerve fibres called the corpus callosum. The cerebrum is further divided in to four lobes: frontal, parietal, occipital, and temporal, which have different functions.
- 4. DIENCEPHELON AND BRAIN STEM
- 6. Brain stem- The brain stem connects the cerebrum with the spinal cord. It controls many of the functions that we usually do not have to think about, including breathing, swallowing, blood pressure and digestion. The two main parts of the brain stem are the pons and the medulla oblongata. PONS- It links together, or acts as a bridge between, different parts of the brain. The pons helps to relay information from the medulla oblongata to higher parts of the brain. Medulla oblongata- The medulla oblongata is also part of the brain stem and carries messages between the brain and the spinal cord. It is partly responsible for heart rate and lung functioning, and controls reflexes such as swallowing, coughing and the gag reflex.
