Abstract

Background Drug experimentation during adolescence is associated with increased risk of drug addiction relative to any other age group. To further understand the neurobiology underlying such liability, we investigate how early adolescent cocaine experience impacts medial prefrontal cortex (mPFC) network function in adulthood.Methods A noncontingent administration paradigm was used to assess the impact of early adolescent cocaine treatment (rats; postnatal days [PD] 35-40) on the overall inhibitory regulation of mPFC activity in adulthood (PD 65-75) by means of histochemical and in vivo electrophysiological measures combined with pharmacologic manipulations.Results Cocaine exposure during early adolescence yields a distinctive hypermetabolic prefrontal cortex state that was not observed in adult-treated rats (PD 75-80). Local field potential recordings revealed that early adolescent cocaine exposure is associated with an attenuation of mPFC gamma-aminobutyric acid (GABA)ergic inhibition evoked by ventral hippocampal stimulation at beta and gamma frequencies that endures throughout adulthood. Such cocaine-induced mPFC disinhibition was not observed in adult-exposed animals. Furthermore, the normal developmental upregulation of parvalbumin immunoreactivity observed in the mPFC from PD 35 to PD 65 is lacking following early adolescent cocaine treatment.Conclusions Our data indicate that repeated cocaine exposure during early adolescence can elicit a state of mPFC disinhibition resulting from a functional impairment of the local prefrontal GABAergic network that endures through adulthood. A lack of acquisition of prefrontal GABAergic function during adolescence could trigger long-term deficits in the mPFC that may increase the susceptibility for the onset of substance abuse and related psychiatric disorders.

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.
