A microinjection of muscimol into the mPFC during ES impairs inhibition of DRN 5-HT cell firing with 150 nm ipsapirone. Open bars indicate rats that received intra-mPFC saline, and filled bars indicate rats that received intra-mPFC muscimol microinjections. Data are expressed as mean + SEM percentage inhibition. Mean percentage inhibition of DRN 5-HT cell firing was significantly different between IS and HC treatments (p < 0.05). *p < 0.05, mean percentage inhibition of DRN 5-HT cell firing was significantly different between ES rats receiving intra-mPFC muscimol and saline.
