PSYC62H3 Chapter Notes - Chapter ch.3: Glutamine Synthetase, Mild Cognitive Impairment, Axon Terminal
Document Summary
Pscy62 drugs and the brain chapter 3 notes. Neurotransmission is the transmission of info from one neuron to the other by releasing neurotransmitters which are chemicals into the synapse. Electrical events within a neuron and the release of neurotransmitters. --hyperpolarization describes inc. diff. btwn +and charges on each side. -a neuron can have many dendrites and one single axon a synapse has an axon terminal, synaptic cleft and postsynaptic terminal. In the csf ---micro lacks the precision of electrophysiology but can be used to answer questions that electro cannot. -neurons release neuro from axon terminal through electrochemical signals called nerve impulses they are made up of changes from resting potential to ap. -concentration gradient tries to maintain a balance btwn these ions on either side of the mem. so as k ions become more conc. inside neuron some k through channels will exit due to conc. gradient. --the electrostatic attraction and conc. gradient maintains a relatively constant rp.
