Temporal and Spatial Summation

NEURO-0EKOA3

Synaptic potentials can be added together to generate a larger postsynaptic response. Such phenomenon is called summation.

Choose the statement that is CORRECT about temporal and spatial summation.

A

When synaptic potentials from the same synapse arrive in rapid succession, they can add together in the pre-synaptic neuron, and this is called temporal summation.

B

When synaptic potentials from the same synapse arrive in rapid succession, they can add together in the postsynaptic neuron, and this is called temporal summation.

C

When sequential synaptic potentials originating at different synaptic sites are summed in the postsynaptic neuron, spatial summation occurs.

D

Temporal and spatial summation only apply to excitatory postsynaptic potentials (EPSPs).
