Abstract(in English) | This study aims to elucidate actions of acetylcholine on corticostriatal synaptic transmission and the membrane excitability of striatal cholinergic interneurons. Whole-cell recordings were obtained from cholinergic interneurons in slice preparations of rats (postnatal day 14-23). Stimulation of the subcortical white matter evoked excitatory postsynaptic potentials (EPSPs) in cholinergic interneurons. Bath application of a muscarinic recepter agonist caused a slow depolarization and reduced the EPSP amplitude. This depolarization was antagonized by tetrodotoxin, a selective blocker of Na^+ channels. These data suggest that acetylcholine in the striatum promotes the membrane excitability of cholinergic interneurons indirectly and inhibits inputs from cortex to cholinergic interneurons. |
