Cholinergic interneurons striatum
WebThe striatum has the highest levels of cholinergic markers in the brain, including ACh, choline acetyltransferase (ChAT), and acetylcholinesterase (AChE) ( Macintosh, 1941; Hebb and Silver, 1961; Woolf et al., 1984 ). Such a high density of cholinergic markers underscores the importance of ACh neurotransmission in the striatum. WebThe cholinergic interneurons in turn project to GABAergic projection neurons, which inhibit the lateral pallidum segment. We hypothesize that much of the motor dysfunction in both human PD and the measurable deficits in the rat hemi-Parkinson model is due to a lack of inhibition of cholinergic interneurons in the CPu by dopamine.

WebMar 2, 2024 · Str interneurons comprise cholinergic interneurons (ChIs) and GABAergic interneurons. While ChIs comprise a single type, GABAergic interneurons comprise multiple types; the most prominent are fast-spiking interneurons (FSIs) expressing parvalbumin (PV). WebThis information is suspected to influence action selection via PF inputs onto cholinergic interneurons (CINs) in the dorsomedial striatum, which is thought to modulate local spiny projection neurons (SPNs), which then co-ordinate to select actions following the currently inferred internal state (Bradfield et al., 2013a; Matamales et al., 2016 ...
