synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons.
Lesechka [4]

Synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons is called Hebbian Synapse.

<h3>What is Synapse?</h3>

A synapse is a component of the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to an additional neuron or to the target effector cell.

The transfer of nerve impulses from one neuron to another requires synapses.

The synapse contributes to the development of memory. Because of the signaling mechanisms of the receptors, which are activated by neurotransmitters across the synaptic cleft, the connection between the two neurons is strengthened when both neurons are engaged at the same time. The capacity of two interconnected brain circuits is thought to influence how well memories are stored. Long-term potentiation is the name for this process of synapse strengthening.

baherus [9]

Answer:

Repolarization

Explanation:

Complete repolarization is achieved by the sodium pump. This actively pumps all the Na+ ti the outside and all the K+ to the inside. The pump requires energy in the form of ATP and is inhibited by metabolic poisons. Entry of Na+ is immediately followed by an increase in the permeability of the membrane to K+. These diffuse rapidly to the outside due to the concentration gradient. Being positively charged, the K+ reverses the polarity of the membrane making the outside positive.
