PSY 101 EXAM 2 STUDY GUIDE NEUROSCIENCE Neurons vs glia Structures and functions of parts of neuron (e.g. dendrites, soma, axon, terminals) The electrochemical process of neural communication Resting potential vs threshold of excitation (AKA summation threshold) Sodium & potassium ions (channels, charges, distribution at rest vs firing) Action potential (ion movement & distribution, changes in voltage inside vs outside) Neurotransmitters, vesicles, events at synapse Multiple sclerosis Glutamate vs GABA Organization of nervous system (see “flowchart” of organization hierarchy) Central, peripheral, somatic, autonomic, sympathetic, parasympathetic nervous systems Nerves Exactly how is parasympathetic nervous system different than sympathetic nervous system Flight or flight Corpus callosum Grey vs white matter Cortex and lobes Motor vs sensory cortex Subcortical structures and the brain stem Prefrontal cortex & executive functions Prefrontal lobotomy Hind brain structures (pons, medulla, cerebellum) Hippocampus vs amygdala vs hypothalamus SLEEP Circadian rhythms Zeitgebers and resetting body clock Melatonin Jet lag (phase advance vs phase delay) Theories for why we need to sleep EEG Stages of sleep (differences in mental state, physiological activity, brain wave patterns, events like dreaming or sleep walking) Order of stages of sleep Sleep disorders (know all of them!) Theory for dreams
