FIG. 3.

Evoked thalamic responses onto FS neurons are unaffected. A: example of thalamically evoked EPSPs in a WT layer 4 FS neuron. A minimal stimulation method was used to obtain a mix of successes and failures of evoked transmission where successes represent putative unitary responses. Scale bars: 1 mV, 5 ms. B and C: summary of minimal stimulation data indicating no change in the cumulative distribution (B) or average EPSP size (C) originating from thalamic afferents. Sample number is stimulus site number obtained from 16 and 20 cells. The numbers in the graph are greater because 2 stimulus sites were examined for a single cell in a subset of recordings.
