Optogenetic stimulation of infralimbic PFC reproduces ketamine’s rapid and sustained antidepressant actions
Open accessAbstract
Significance: Clinical studies report that a single, low dose of ketamine produces a rapid antidepressant response in treatment-resistant depressed patients. Although rodent studies have begun to elucidate the molecular mechanisms underlying the behavioral actions of ketamine, the brain regions and cellular mechanisms have not been defined. Using a combination of pharmacological silencing and optogenetic stimulation approaches, the results of the current study demonstrate that ketamine infusion or optogenetic stimulation of the infalimbic prefrontal cortex produces antidepressant behavioral and synaptic responses similar to the actions of systemic ketamine. These findings further elucidate the mechanisms underlying the therapeutic actions of ketamine and will enhance the development of safer rapid-acting and efficacious agents.

“In contrast, prolonged ILc pyramidal stimulation for 60 min mirrored the putative antidepressant effects of ketamine on sucrose preference, while neuronal silencing of ILc (and not PLc), using the GABA-A agonist, muscimol, blocked the actions of ketamine, 24 h later [63].”

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.
