Review Nature 399 A15
The document discusses emerging insights into the genetic causes and cellular mechanisms of epilepsy. It summarizes that mutations in ion channel genes have been identified that cause rare inherited forms of epilepsy. These include mutations in sodium channel genes linked to generalized epilepsy with febrile seizures plus, potassium channel genes linked to benign familial neonatal convulsions, and nicotinic acetylcholine receptor genes linked to autosomal dominant nocturnal frontal-lobe epilepsy. Characterization of these mutant genes and channels in model systems provides insights into how the mutations may increase neuronal excitability and cause seizures. Identifying the genetic causes of rare epilepsies provides opportunities to understand common mechanisms and develop new therapies for more prevalent forms.
Hippocampus
The hippocampus is located in the medial temporal lobe below the cortex and plays an important role in memory consolidation, emotions, navigation, and spatial orientation. Three studies were summarized. The first found that more physically fit children had a larger hippocampus. The second found that long-term ecstasy users had a smaller hippocampus. The third found that Gulf War veterans who had recovered from PTSD had larger hippocampal volumes than those who had not recovered. Damage to the hippocampus can cause amnesia or memory loss and may eventually lead to Alzheimer's disease.

The document discusses 5 brain states related to threat and emotional responses. Brain state 1 has the neocortex and subcortex as primary areas, while state 5 is dominated by the brainstem. States 1-3 are considered homeostatic, involving physiological processing with the vagal brake engaged. These states promote prosocial development. States 4-5 are allostatic with the vagal brake disengaged, processing through the midbrain and brainstem. These states involve hedonic, ego-based rewards that activate short-term positive but long-term negative emotions, failing to promote emotional and social development.

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.

Emotion13
Emotion is defined as having cognitive, physiological, and behavioral components. The limbic system, specifically the amygdala, plays an important role in emotions like fear and rage. The right hemisphere of the brain is also active during emotional displays and damage can leave one emotionally indifferent. Emotions produce sympathetic nervous system responses like increased heart rate and respiration. Plutchik's theory proposes eight primary emotions that combine to form secondary emotions. James-Lange and Cannon-Bard theories differ on the temporal order of physiological and emotional awareness during emotional experiences. Culture influences the expression and meaning of emotions through display rules.

Finally, it discusses the concept of perceptual set and how prior knowledge and expectations can influence what we perceive.
Sensation
Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energy from our environment. Perception involves organizing and interpreting sensory information to recognize meaningful objects and events. Psychophysics studies the relationship between physical stimulus characteristics and our psychological experience of them. Thresholds refer to the minimum levels of stimulation needed for detection, and signal detection theory examines how we detect faint stimuli.
