Dopaminergic Suppression of Synaptic Transmission in the Lateral Entorhinal Cortex
Figure 7
The number of action
potentials elicited by positive current steps is reduced by dopamine. (a) Traces show action potentials generated in
response to 500 milliseconds duration, 60 pA current steps before and after
application of 50 M dopamine. The
example shown reflects a particularly large reduction to only one action
potential following application of dopamine. Action potentials are truncated. (b) Group data show a reduction in firing for both the 10 and 50 M
conditions but only the reduction in the 10 M condition was significant.
