Both adapting (RSNP) and nonadapting (FS) interneurons mediate thalamocortical feedforward inhibition. A, Intrinsic firing patterns of three inhibitory interneurons that fired in response to thalamic stimulation, illustrating the large differences in spike frequency adaptation during the 500 msec current pulse. The leftand middle traces are, respectively, from cells 1 and 2 in Figure 4. B, The distribution of spike frequency adaptation ratios in a sample of 56 inhibitory interneurons. The value of 0.8 was selected as a separation point between the FS and RSNP cell classes. C, Probability of thalamocortically evoked firing of 24 FS and 33 RSNP neurons. Differences were statistically insignificant.
