B. Left: representative traces of GABA mIPSCs recorded in layer V pyramidal neurons are illustrated. Right: the histograms represent means ± S.E.M. of GABA mIPSC frequency and amplitude measured during the last minute of recording. The mIPSC frequency is: 3.2 ± 0.4 Hz and 1.3 ± 0.2 Hz for Vehicle (n=9 from N= 4) and THC (n=7 from N= 4) conditions, respectively, p < 0.001 and 2.5 ± 0.2 Hz and 4.1 ± 0.4 Hz for THC+SB258585 (n=8 from N= 4) and THC+Rapa (n=8 from N= 4) conditions, respectively, p < 0.01 and p < 0.001 vs. THC-injected mice.
