Title:
Ecstasy - acute effects
Description:
When a person uses ecstasy, the increase in serotonin in different brain regions causes psychological effects. These include elevated mood and feelings of empathy. The ecstasy is also reinforcing, which means that its pleasurable properties increase the likelihood that the person will take it again. Many of the psychological effects of ecstasy are due to its actions within the limbic system (the amygdala, in red, and hippocampus, in blue, especially). The ability of ecstasy to produce mild stimulation is due to its actions in another part of the limbic system—the basal ganglia (in purple). It is here where ecstasy's effects on the dopamine system may be important. The heightened perceptions involve the actions of ecstasy in the neocortex (in yellow). Ecstasy can also reduce the appetite, because it acts in the hypothalamus (in green), which controls feeding behavior.
