Figure 10. Effect of disinhibition and subsequent muscarinic receptor block on whisker-evoked responses in VPM neurons.

Figure 10

Single-unit response in VPM to whisker stimulation displayed as the binned (2 ms bins) sum of 30 trials each consisting of 15 whisker stimuli delivered at 40 Hz (left panels), 20 Hz (middle) and 10 Hz (right), before (upper panels) and during the application of BMI and CGP35348 (middle) and during the application of BMI, CGP35348 and scopolamine (lower) to VPM. Notice that the single unit responds to whisker stimulation at up to 40 Hz during disinhibition produced by BMI and CGP35348, but that this effect is eliminated by the muscarinic antagonist scopolamine.
