Serotonergic regulation of neuronal excitability in the prefrontal cortex

Open access
Andrade, Rodrigo·2011·Neuropharmacology

Abstract

The cerebral cortex receives a dense serotonergic innervation originating predominantly from the dorsal raphe nucleus. This innervation regulates cortical functioning by activating multiple serotonin receptors that are differentially expressed by pyramidal cells and interneurons. Electrophysiological studies in the prefrontal cortex indicate that receptors of the 5-HT(1A) and 5-HT(2A) subtypes are the main serotonin receptors regulating membrane excitability in pyramidal cells. Most pyramidal cells in layer V coexpress 5-HT(1A) and 5-HT(2A) receptors that together regulate how these neurons encode excitatory input into neuronal firing. In contrast, a subset of large pyramidal cells of deep layer V appears to express exclusively 5-HT(2A) receptors that depolarize and excite these cells. Serotonin also depolarizes and excites at least two classes of GABAergic interneurons by acting on 5-HT(3) and 5-HT(2A) receptors. The differential expression of serotonin receptors in different pyramidal cells and interneurons is consistent with a growing appreciation of the anatomical, molecular and functional heterogeneity of pyramidal cells and interneurons of the cerebral cortex. These findings begin to lay the ground for a cellular-level understanding of the serotonergic regulation of the prefrontal cortex.

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.
