P2X receptor-mediated excitatory synaptic currents in somatosensory cortex.


Fast P2X receptor-mediated excitatory postsynaptic current (EPSC) was found in pyramidal neurones of layer V of somatosensory cortex in slices acutely isolated from the brain of 17- to 22-day-old rats. The EPSCs were elicited by field electrical stimulation in the layer VI at 0.1 Hz in the presence of picrotoxin. When the glutamatergic EPSC was blocked by… (More)
