Dopamine Modulation of Prefrontal Cortical Interneurons Changes during Adolescence

Open access
Tseng, K.-Y., O'Donnell, P.·2006·Cerebral Cortex

Abstract

Adolescence is marked by profound psychological and neuroendocrine changes. Cognitive functions that depend on the prefrontal cortex and dopamine (DA), such as decision making, are acquired or refined during adolescence; yet, little is known about how neural circuits mature in the transition to adulthood. Here, we conducted electrophysiological recordings in rat brain slices, unveiling an enhancement of the excitability of interneurons, which are important for cortical network activity, by D(1) and D(2) DA receptors. The D(2) effect was observed in slices from adult (postnatal day [PD] > 50) but not preadolescent (PD < 36) animals suggesting a possible neural substrate for the maturation of DA-dependent prefrontal cortical functions during or after adolescence and identifying a critical neural population that could be involved in the periadolescent onset of neuropsychiatric disorders, such as schizophrenia.

  • Prior to adolescence, D2 stimulation elicits either no effect or only weak inhibition on interneurons; in adult animals, stimulation of D2 receptors is strongly excitatory and results in robust firing of interneurons and potent inhibition of their pyramidal cell targets.

    “Prior to adolescence, D2 stimulation elicits either no effect or only weak inhibition on interneurons. However, in adult animals stimulation of D2 receptors is strongly excitatory and therefore results in robust firing of interneurons and potent inhibition of their pyramidal cell targets.”

  • Recent evidence has established that D2 dopamine receptors on interneurons undergo a profound maturational change during adolescence.

    “recent evidence has established that D2 dopamine receptors on interneurons undergo a profound maturational change during adolescence.62, 63, 64”

    From A role for synaptic plasticity in the adolescent development of executive function (2013) · cites this paper as [64]

    The Abstract and Discussion report that D2-mediated excitation of rat prefrontal interneurons is present in adults but not preadolescent animals, supporting a maturational change in D2 modulation. The Discussion says it remains unclear whether the effect is a direct action on interneurons, so the paper does not establish that the receptors on those cells themselves change during adolescence.

  • D2 receptors switch from inhibitory to excitatory on parvalbumin interneurons in the mPFC during adolescence.

    “D2 receptors switch from inhibitory to excitatory on parvalbumin interneurons in the mPFC during adolescence (Tseng and O'Donnell, 2007).”

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.
