Effects of ecstasy on brain function. Computer artwork representing the effects of MDMA (3,4-methylenedioxy-N-methylamphetamine), or ecstasy, on the nerves (centre) and synapses (nerve junctions, right) of the human brain (left). MDMA produces feelings of energy, euphoria, empathy and love through the release of serotonin and dopamine in the brain. These neurotransmitters are involved in the regulation of mood, with high levels being associated with positive feelings. Its exact mechanism of action remains unclear.
