The part of a post synaptic neuron that is responsible for the integration of incoming signals/post synaptic potentials is the axon hillock.

Here's why:

a. All of the others are equally involved - This is incorrect. While all parts of the neuron play a role in signal transmission, not all parts are involved in the integration of signals.

b. The axon hillock - This is correct. The axon hillock is the part of the neuron that connects the cell body (soma) to the axon. It is where the summation of all incoming signals (excitatory and inhibitory) occurs. If the total strength of the signals exceeds a certain threshold, an action potential is generated and propagated down the axon.

c. The Nissl bodies - This is incorrect. Nissl bodies are involved in protein synthesis, not signal integration.

d. The nucleus - This is incorrect. The nucleus contains the neuron's genetic material and controls the cell's growth and reproduction, not signal integration.

e. Distal dendrites - This is incorrect. While dendrites do receive signals from other neurons, the integration of these signals occurs at the axon hillock, not the dendrites themselves.
