Cholinergic Neurons (Brain) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Brain Cholinergic Neurons are neurons that synthesize and release the neurotransmitter acetylcholine (ACh).[1] In the central nervous system, cholinergic neurons are primarily concentrated in the basal forebrain complex, which includes the medial septum, diagonal band of Broca, and nucleus basalis of Meynert.[2]
These neurons provide the major cholinergic innervation to the hippocampus and cerebral cortex and are essential for cognitive functions including attention, learning, and memory.[3]
