Which of the Following Statements About Summation in the Nervous

Multiple Choice

Which of the following statements about summation in the nervous system is INCORRECT?

A) Summation of signals in neuronal pathways allows integration of multiple subthreshold changes in local potential.
B) Spatial summation occurs when local potentials originate from different locations on the posynaptic neuron.
C) Spatial summation also occurs when local potentials overlap in time.
D) Both spatial and temporal summation can lead to either inhibition or stimulation depending upon the signal type.
E) A single presynaptic action potential usually does not cause a sufficiently large postsynaptic local potential to cause the postsynaptic cell to reach threshold.
