Dopaminergic Suppression of Synaptic Transmission in the Lateral Entorhinal Cortex
Figure 9
Blocking potassium channels prevent
the dopamine-induced reduction in input resistance. (a) Blockade of Na+ channels with 0.5 M TTX does not prevent the reduction of peak or steady-state input resistance
induced by 50 M dopamine (*,). Conventions are as in Figure 8. (b) In contrast, coapplication of the K+ channel blocker TEA (30 mM) prevented the dopamine-induced reduction in input
resistance.
