Dopamine–glutamate interactions may contribute to persistent electrical activity in the prefrontal cortex (PFC). We tested whether a D1modulation of NMDA function can result in persistent depolarizationin vitro. D1–NMDA co-activation yielded depolarizing plateaus resemblingin vivoup 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.
