Inward rectifier K<sup>+sup> channel and T-type Ca<sup>2 sp>+sup> channel contribute to enhancement of GABAergic transmission induced by β<sub>1sub>-adrenoceptor in the prefrontal cortex
Dobutamine enhances GABAergic transmission onto pyramidal neurons. T-type Ca2 + channel is involved in dobutamine-enhanced GABA release. Dobutamine depolarizates GABAergic interneurons through inhibition of Kir.
