direct cholinergic innervation of the striatal complex from the brainstem

Extracted Explainers

What the tool is doing

This paper identifies a direct cholinergic projection from brainstem nuclei to the striatal complex. It reframes striatal cholinergic innervation as arising from both intrinsic and extrinsic sources.

Source 1DOIPubMed

What problem it solves

It solves an anatomical interpretation problem by challenging the assumption that striatal acetylcholine comes only from local cholinergic interneurons.

Source 1DOIPubMed

What it does not solve

The abstract does not establish the full functional consequences or quantitative contribution of this projection during behavior.

Source 1DOIPubMed

Alternatives

The contrasted alternative in the abstract is the prior model in which acetylcholine release in striatum originates exclusively from striatal cholinergic interneurons.

Evidence Snippets

Here we show that cholinergic neurons in the brainstem also provide a direct innervation of the striatal complex.

Claim 1anatomical projectionsupports2014Source 1DOIPubMed

Cholinergic neurons in the brainstem provide a direct innervation of the striatal complex.

Claim 2functional interpretationsupports2014Source 1DOIPubMed

Cholinergic interneurons and cholinergic neurons of the brainstem likely play different but complementary roles in striatal information processing during reward-related paradigms.

Claim 3topographic mappingsupports2014Source 1DOIPubMed

Rostral PPN preferentially innervates the dorsolateral striatum, whereas LDT preferentially innervates the medial striatum and nucleus accumbens core.
