Brain tumor - Symptoms and causes - Mayo Clinic Perhaps, but by providing a minimal action it allows considerable normalization of brain function. But when the moment comes to strike, the little, tachyzoites alter their hosts brain chemistry. It actually involves sociology, behavioral psychology, and employing principles . In addicts, cues that normally would have no particular importance to survival or pleasuresuch as a line of white powder, a cigarette, or a bottle of brown liquidactivate this same reward system.
