Entorhinal Cortex
AD also involves loss of neurons, beginning in the entorhinal cortex and later spreading to the neocortex (Braak et al., 2006); early in the disease, nicotinic acetylcholine receptors (nAChRs) are lost (Kadir et al., 2006). PubMed:19293145

Amyloid plaques form in the entorhinal cortex of patients with Alzheimer’s disease and this region, which connects the neocortex and the hippocampus, plays a crucial part in memory. it has been suggested that plaques in this region represent the lytic remnants of degenerated, Abeta1–42-burdened pyramidal neurons, and that amyloid internalization depends on alpha7 nAChR mediated Ca2+ entry162. Of interest, chronic nicotine treatment has been shown to reduce the plaque burden in animal models of Alzheimer’s disease123. PubMed:19721446
