It especially affects two brain regions: the cerebral cortex--involved in mood, cognition, and perception--and the locus ceruleus, which receives sensory signals. In stress, the locus ceruleus fires more rapidly and delivers the arousal-producing neurotransmitter norepinephrine to many diverse regions in the brain. Although the pigmented locus ceruleus region of the brain also contains neuromelanin, it is largely immune to the cell-destroying effects of low doses of MPTP. |
