PSYCH 149 Lecture Notes - Lecture 2: Ampa Receptor, Axon Terminal, Dopamine Receptor D2
Document Summary
Lecture 2, jan. 7: the neuron structure (see lecture 2 powerpoint, a cell with a cell body, inside is the nucleus, receiving end-dendrite, sending end is the axon terminal. Terminal botton of one neuron is relasing a nuerotransmitter (made in the cell bod and when it is activated it travels (polarity increases) it travels down the axon, to the axon terminals to send it. Exogenous: chemicals that enter from the body from outside: can be agonist and antagonist, agonist: chemical that facilitates/minimates the nuerotrasnmitter. Working with the nuetroasmitters: antagonist: acts against the chemical by blocking its path. Impedes its activity: two main neurotransmitters, excitatory: activates post synaptic cell, glutamate activates ampa receptor. Inhibitory: decreases the activity of post synaptic cell, makes it non active. Drugs that alter serotonin treat depression, anxiety, social phobias: opioids. Binds to class g portine receports: dopamine. Does play a role in reward learning and reward guided behavior. Heavily involved in schizophrenia: have too much dopamine.
