Figure 5.
Inhibitory synaptic transmission on barrel cortical pyramidal neurons decreases after pairing WS and OS. Spontaneous inhibitory postsynaptic currents (sIPSCs) were recorded on glutamatergic neurons in cortical slices under voltage-clamp (holding potential at −65 mV) in presence of 10 μM CNQX and 40 μM D-AP5. (a) Traces show sIPSCs recorded on the neurons from controls (dark-blue in left panel) and CR-formation (dark-red in right). The bottom traces present the expanded waveforms selected from top traces. Calibration bars are 25 pA, 1 second (top) and 100 ms (bottom). (b) shows cumulative probability versus sIPSC amplitudes from CR-formation (dark-red symbols, n = 12) and control (dark-blue symbols, n = 12). (c) shows cumulative probability versus inter-sIPSC intervals from CR-formations (dark-red symbols, n = 12) and controls (dark-blue symbols, n = 12).
