WebJul 1, 2024 · The cholinergic hypothesis of Alzheimer's disease centres on the progressive loss of limbic and neocortical cholinergic innervation. Neurofibrillary degeneration in the basal forebrain is believed to be the primary cause for the dysfunction and death of forebrain cholinergic neurons, giving rise to a widespread presynaptic cholinergic denervation. Web15 hours ago · Basal forebrain cholinergic systems constitute discrete cell groups that innervate numerous brain regions. For instance, neurons in the medial septum (MS) and vertical diagonal band of Broca (vDB) predominantly extend their axons to the hippocampus, forming the septo-hippocampal pathways [ 13, 14 ]. jim wolford charlotte nc https://redhotheathens.com
