Ipsapirone-mediated inhibition of DRN 5-HT cell firing is selectively impaired 24 h after IS. The white bar indicates non-stressed HC, the gray bar indicates IS rats that were killed immediately after IS, the black bar indicates rats killed 24 h after IS, and the patterned bar represents rats that were killed 7 d after IS. The data are expressed as mean + SEM percentage inhibition. Mean percentage inhibition was significantly different among groups (p < 0.05). *p < 0.05, Dunnett's multiple comparison test revealed that only the 24 h time point was significantly different from HC.
