Document Summary

Neuroanatomical: major brain structures and their organization. Physiological: major contributions of physiological systems (ex: autonomic nervous system, hormones, etc. ) How the brain interacts with/is informed by the rest of the body. Environmental physical layout of the environment, people. Structure of a neuron (be able to explain how the neuron functions**) Neuron plays a role in our consciousness; receives information, integrates information and transmits information forwards (communication device/relay station) Axon: long fiber that conducts impulses away from the cell body. Ionic process but is electrically regulated: succession of ion channels opening and closing, absolute refractory period. What happens with more and more excitation: more and more identical action potentials. Key neurotransmitters (know the top 6 neurotransmitters and their function**test question) Glutamate excitatory: cognitive seizures, motivation (does the opposite of gaba) Gaba inhibitory: seizures, anxiety (ex: anti-anxiety meds help gaba bind more effectively to post- synaptic receptors) -> over active brain (does the opposite of glutamate)
