Document Summary

*synaptic transmission: explains the delay in response latency for a reflex arc. Acetylcholine (ach) functions in excitatory and inhibitory systems (related to memory, motor, behavioural inhibition) Norepinephrine (ne) functions in excitatory and inhibitory systems (related to arousal, eating) Dopamine (da) functions in inhibitory, sometimes excitatory, systems (related to arousal, voluntary movement) Seratonin (5-ht) functions in inhibitory and excitatory systems (related to sleep, thermoregulation) Gamma aminobutynic acid (gaba) functions in inhibitory systems (related to motor behaviour) (bolded appear most often is psychology) Also knowing the results of the following drugs: nicotine stimulates receptor molecules, duplicating effects of ach (agonist chemical that stimulates activities, caffeine blocks adenosine receptor sites (antagonist reduces activities by blocking receptor sites) Neuron summary: all neurons fire they all generate action potentials, action potential happens or it doesn"t no in between, intensity coded as frequency. Hypothalamus are stringy things with swelling at the end.
