Question
Chapter 4, Problem 4RE
Summary Introduction
To Determine:
If the given statement is 'postsynaptic neurons can either excite or inhibit presynaptic neurons' true or false.
Introduction:
An action potential can be defined as a rapid rise and a subsequent fall in the voltage or membrane potential through a cellular membrane with a distinguishing pattern. Synapse is a junction present between the two neurons.

- A postsynaptic neuron has three presynaptic inputs from neurons X, Y, and Z. When X and Y are stimulated simultaneously and repeatedly, the postsynaptic neuron reaches threshold and undergoes an action potential. When X and Z are stimulated simultaneously, however, there is no change in the membrane potential of the postsynaptic neuron. Which of the following is correct? Select one: A. The simultaneous stimulation of X and Z is an example of temporal summation. O B. The simultaneous stimulation of X and Y is an example of temporal summation. O C. The repeated rapid stimulation of X is an example of spatial summation. O D. The stimulation of Y causes an IPSP in the postsynaptic neuron. O E.
