"Nerve cells originating in the locus coeruleus extend throughout the brain and spinal cord via an extensive branching system, where they release norepinephrine to regulate heartbeat, blood pressure, arousal, memory, and attention."
"In Parkinson’s, the locus coeruleus is one of the first brain regions to start degenerating. This has been associated with a range of the disease’s nonmotor symptoms."
