FIG. 4.
Inhibitory postsynaptic currents (IPSCs) originating from FS neurons are unaltered in the Fmr1 KO. A: unitary IPSCs targeting layer 4 excitatory neurons in slices obtained from 2-wk-old animals. Only 1st 4 EPSCs shown. Scale bars: 1,000 and 10 pA, 50 ms. Inhibitory drive (B) and short-term plasticity (C; for 2 wk: n = 14,22; for 4 wk, n = 22,25) are unaltered at both ages.
