The VTA is very high with the electric stimulations, when eating, drinking, and the use of cocaine. The need for cocaine is increased as the use becomes abuse. They study the effects of this on the system and see how they affect the cholinergic cells. The loss of these cells did not affect the use of cocaine, and was not a factor. They also did this study with heroine and yielded the same
