Figure 2

Lack of correlation between tonic inhibitory currents and resting membrane potentials as well as between tonic inhibitory currents and total sIPSC activity. A). Graph shows a plot of tonic inhibitory currents against membrane potentials for each recorded neuron (n = 30). B). Graph shows a plot of tonic inhibitory current against sIPSC frequency (n = 30). Tonic inhibitory currents were revealed by the applications of 20 μM bicuculline. Both resting membrane potentials and sIPSCs were measured before the application of bicuculline.
