GABA (1 mm) was pressure-applied from a patch pipette with a tip diameter of <1 μm. Dendritic applications were >150 μm apart from soma. Reversal potentials were determined from current–voltage plots in which each point was the average of three applications, and the linear regression was calculated from three to seven data points on both sides of E_GABA. Mean values ± SEM are given for the number of cells indicated in brackets. Values are corrected for liquid junction potentials.
