L33 Psych 100B Study Guide - Final Guide: Procaine, Multiple Sclerosis, Reuptake
Document Summary
Characteristics of axon potential: action potential is an electric charge, propagates down the axon, action potential is all or none. No such thing as partially fired neuron. Behavior and the action potential: multiple sclerosis and myelin, anesthetics such as novocain work by blocking ion channels and preventing action potential. Vesicles stored in terminal buttons contain neurotransmitters: calcium flows in - neurotransmitters released into synaptic gap, receptors on dendrites of postsynaptic neuron. Lock and key model: binding of neurotransmitters to receptors causes action potential in postsynaptic neuron, following action potential in post-synaptic neuron. Others taken back up (re-uptake) by pre-synaptic (releasing) neuron. Ecstasy and parkinson"s disease: how could some neurotransmitter cause both motor disruptions and schizophrenia. Not only neurotransmitters, but where in brain. Dopamine also inherits ability to experience pleasure. Even as recent as 1960"s treatment had not progressed. Revolution in treatment: schizophrenia and dopamine, serotonin and mood disorders. Prozac (selective serotonin re-uptake inhibitor ssri) as treatment for depression.
