Post-pubertal Emergence of Prefrontal Cortical Up States Induced by D1-NMDA Co-activation

Tseng, K. Y.·2004·Cerebral Cortex

Abstract

Dopamine-glutamate interactions may contribute to persistent electrical activity in the prefrontal cortex (PFC). We tested whether a D1 modulation of NMDA function can result in persistent depolarization in vitro. D1-NMDA co-activation yielded depolarizing plateaus resembling in vivo up states in PFC pyramidal neurons recorded in slices from adult (PD 45-65), but not pre-pubertal (PD 29-38) rats. These plateaus required intracellular Ca2+, activation of L-type Ca2+ channels and protein kinase A. These events were eliminated by intracellular administration of the voltage-gated Na+ channel blocker QX-314 or by interrupting synaptic activity with bath application of tetrodotoxin or the AMPA antagonist CNQX, suggesting that they require both intrinsic and synaptic mechanisms. These recurrent depolarizations could constitute important elements in cortical information processing, allowing synaptic plasticity and memory functions. Acquiring these PFC D1-NMDA interactions after puberty may be a critical element for developing mature cognitive abilities.

  • During embryonic development there is convergence of the various neurotransmitter signaling pathways and they influence each other's development and functioning.

    “There is, furthermore, ample evidence now that during embryonic development there is convergence of the various neurotransmitter signaling pathways and influence each other’s development and functioning [153, 227–231].”

  • Noradrenergic and dopaminergic projections towards forebrain regions, as well as dopaminergic-glutamatergic and dopaminergic-cholinergic interactions, control PFC maturation and functioning.

    “The same holds true for noradrenergic and dopaminergic projections towards forebrain regions as well as dopaminergic-glutamatergic and dopaminergic-cholinergic interactions controlling PFC maturation and functioning [227, 228, 231].”

    From Development of prefrontal cortex (2022) · cites this paper as [228]

  • The D1-NMDA interaction in the rodent PFC becomes more robust during adolescence, allowing the emergence of persistent depolarizations in adult brain slices when D1 and NMDA receptors are coactivated.

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.
