Question
Chapter 12, Problem 26CP
Summary Introduction
To determine:
Refer to checkpoint question 25, determine whether the action potential will be generated or not if a second, identical EPSP occurs immediately after the first.
Introduction:
EPSP can be abbreviated as excitatory postsynaptic potential. It is the graded potential that develops in the membrane of a postsynaptic cell due to binding of neurotransmitters to its receptors on the membrane.

If extracellular [Na1] is elevated, how would the resting potential and action potential of a neuron change?
If postsynaptic membrane permeability is increased, is theneuron more easily stimulated or less excitable?
If all the Ca2+ in the fluid surrounding a neuron were removed, how would this affect the transmission of information within and between neurons?
