Abstract

Significance: There is a vast literature linking individual neurotransmitters with specific brain function and disorders, often with significant overlap. For instance, serotonin (5-HT), glutamate, and endocannabinoids have been linked to several biological functions, such as mood regulation, reward, and decision making, as well as to pathologies, such as depressive and anxiety disorders. It is becoming axiomatic that such neurochemical-based models need to be incorporated within comprehensive and dynamic circuit-based frameworks to apprehend fully the neural basis of these functions. Here, we defined the mesoscale-level functional organization of the medial prefrontal cortex input to the dorsal raphe nucleus and how this circuit is modulated by cannabinoid (CB) signalling. This network-based functional framework may help to explain several of the mood-regulating features of both 5-HT and CBs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
