The locus coeruleus is a small cluster of neurons located in the brainstem, specifically in the pons, that plays a crucial role in the regulation of arousal, attention, and the body's stress response. It is known for its widespread projections throughout the brain, releasing norepinephrine, which helps modulate various cognitive functions and enhances alertness. This area is particularly relevant in discussions about cognitive enhancement as it directly influences attention, learning, and memory processes.
