Which step of neural communication involves a neuron assessing the signals that it is receiving from other sources?

Answer is integration.

Explanation:

Neural communication is a situation where the neurons especially the sensory neurons interact with the stimuli received, and the transformation of the stimuli is sent to the brain via chains of neurons. This is a able to occur through a process known as electrochemical process.

The process is described as electrochemical process because the action potential is electrical while transmission through the synapse is chemical.

The process of combining information is known as integration. And the neurons has an essential part that is capable of combining information, this part is dendrite.

It is very important to know that, a study on how information is processed by the brain, and responses are produced, is known as functional integration.
