Dendritic and somatic GABA applications generated Cl⁻ currents with different reversal potentials. In the same cell, currents induced by focal application of GABA (1 mm) to a dendrite (▪) or the soma (●) had different reversal potentials. Application sites as shown for a cell in theinset (s, somatic; d, dendritic). Recording conditions were 2 mm[K⁺]_o and 15 mm[A⁻]_pip. Letters mark the points on the current–voltage relationship at which the sample currents shown above had been recorded. Symbolsrepresent the mean of three consecutive applications. Note the voltage range at which GABA evoked an outward current in the dendrite and an inward current at the soma.
