Astrocyte inactivation attenuates the mGlu2 component of the Group II effect on sensory inhibition in the VB. a Raster displays and PSTHs of responses of a VB neuron (CVB138a) to train stimulation (50 ms bins, 6 trials) of a single vibrissa under normal conditions and in the presence of fluorocitrate (20 nA; 10 min) during a control period, upon iontophoretic application of either LY487379 (50 nA, 2 min) or LY354740 (50 nA, 2 min), and during recovery. Abscissa indicated on the bottom left raster and PSTH plot applies to all plots. b Bars represent the mean % of control (±SEM) of responses to train stimulation of single vibrissae (n = 6) to application of either LY487379 or LY354740 under normal conditions and in the presence of fluorocitrate. *p < 0.05.
