The height of a wave or the amount of the wave carries is the amplitude.

The height of a wave or the amount of energy the wave carries is the amplitude.

Explanation:

Amplitude is one of the variable properties a wave presents. The amplitude of a wave refers to the maximum of displacement the wave has from its rest position. In other words, the amplitude is the distance from rest position to the wave's crest. The amount of energy the wave carries will affect the amplitude the wave will have as well; as more energy is carries the amplitude will also increase making the distance from rest position to the crest bigger. A high energy wave is characterized with high amplitude as well as a low energy wave is characterized with a low amplitude.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
