An extremely high level of social inhibition is known as Social Anxiety Disorder, though is usually falselyperceived to be the result of a lack of confidence or self esteem.
Function of Electrochemical Impulses: In neurons, cell-to-cell communication is the major role of action potential. In other types of cells, activation of intracellular processes is their major function.
A neural signal is another way of characterizing the electrochemical message that neurons send to each other. When a neuron receives sufficient stimulation in the form of EPSPs, voltage-gated ion channels open, and a signal is sent down the axon to the axon terminal. That is the electrical part of the message.
