K_V1 and K_V3 Potassium Channels Identified at Presynaptic Terminals of the Corticostriatal Synapses in Rat

Figure 2

4 family K⁺ specific blockers do not modify PPF. Representative experiments are shown to exemplify that neither PPR (left upper panels) nor population-spike amplitude (left bottom panels) was modified by exposure to heteropodatoxin (a) or phrixotoxin (b). In this figure and Figures 3–6 horizontal bars indicate time of drug perfusion, the traces recorded before (1) and after (2) exposure to 4 toxins are shown on the right panels.
