Figure 5. Effect of isoproterenol and kainate on the amplitude of IsAHP.
A, sample of traces of IsAHP obtained in control conditions (left) after extracellular application of 5 μm isoproterenol (middle trace) and after 20 min washout (right). Scale bars indicate 20 pA and 1 s. B, the time course of IsAHP amplitude after extracellular application of kainate (200 nm, n= 5). C, time course of IsAHP amplitude for short (n= 4, ▪) and prolonged (10 min, •) application of 5 μm isoproterenol.
