excitatory postsynaptic potential (EPSP)
graded depolarization of a neuron
inhibitory postsynaptic potential (IPSP)
temporary hyperpolarization of a membrane
postsynaptic neurons

presynaptic neurons
neuron on the releasing end of a synapse
reflex arc
circuit of neurons from the sensory neurons to muscle responses that produce a reflex
reflexes
consistent, automatic response to a stimulus
spatial summation
combination of effects of activity from two or more synapses onto a single neuron
spontaneous firing rate
periodic production of action potentials by a neuron in the absence of synaptic input
synapse
point of communication at the gap between two neurons or between a neuron and a muscle
temporal summation
cumulative effect as a result of repeated synaptic stimulation within a brief time
