What will happen if a neuron receives many excitatory signals from neighboring neurons?

The answer is: That will generate an action potential.

Explanation:

Each neuron is connected to numerous neurons, receiving many impulses from them. The total sum of these impulses in the axon is known in the Anglo-Saxon literature as "summation."

If the neuron only receives excitatory impulses, it will generate an action potential.

The answer is: That will generate an action potential.

a neuron is also known as nerve cells and are building blocks for the information system so if a neuron receives many excitatory signals from one next to it then it will transmit information through chemical and electrical signals which are called synapses. Neutral circuits can form when neurons connect to each other.
