1
Q
Excitatory postsynaptic potential (EPSP)
A
graded depolarization
2
Q
Inhibitory postsynaptic potential (IPSP)
A
temporary hyperpolarization of a membrane
3
Q
Postsynaptic neuron
A
neuron that receives transmission from another neuron
4
Q
Presynaptic neuron
A
neuron that delivers transmission to another neuron
5
Q
Reflex arc
A
a circuit from sensory neuron to muscle response
6
Q
Reflexes
A
automatic muscular responses to stimuli
7
Q
Spatial summation
A
summation over time. Combination of effects of activity from two or more synapses onto a single neuron
8
Q
Spontaneous firing rate
A
a periodic production of action potentials even without synaptic input
9
Q
Synapse
A
a specialized gap as a point of communication between two neurons
10
Q
Temporal summation
A
a cumulative effect of repeated stimuli within a brief time
