Dr. pohler is a neurobiologist studying ways to enhance the perception of sound in people with hearing difficulties. he discovers a natural neurotransmitter that increases the chance a neuron will fire an action potential, increasing sensitivity to sound. what is the effect of this neurotransmitter on the receiving neuron?

Excitatory, causing depolarization

Explanation:

Depolarization: The term depolarization is defined as a process through which different cells experience a membrane potential change. Depolarization leads to the swap of the electric charge in the cells that causes to leave a few negative charge into the cell.

Excitatory neurotransmitter: It creates a signal named as action potential in any of the receiving neuron. These neurotransmitters cause excitatory consequences on the neuron i.e, it increases the probability of a neuron to release an action potential.

In the question above, the effect of the neurotransmitter on the receiving neuron is excitatory that causes depolarization.
