Question

Which of the following does NOT describe the process of summation?

a. Two ESPSs are generated at the same time by two separate synapses, bringing the cell to threshold. b. One EPSP and one IPSP cancel each other out. c. Two EPSPs occur close enough in time to bring the cell to threshold. d. One EPSP fails to bring the cell to threshold.

Answer 1

The answer is letter D. One EPSP fails to bring the cell to threshold.There are two types of summations the temporal summation and the spatial summation. the process whereby multiple stimuli can produce a response (in a muscle or nerve or other part) that one stimulus alone does not produce
