Representative examples of the 4 different cell classes that can be identified in cat area 17 by their electrophysiological features. (A–C) IB cell. (D–F) CH cell. (G–I) RS cell. (J–K) FS cell. Log(ISIs) are unimodal in nonburst-generating neurons (I, L) and bimodal in burst-generating neurons (C, F). Action potentials are thinner in the CH cell (E) and in the FS cell (K) in comparison with the IB cell (B) and the RS cell (H). Bursts discharge tends to inactivate in the IB cell (A) but persists for the whole current pulse duration in the CH cell (D). The RS cell shows firing rate adaptation (G) but the FS cells do not (J). Horizontal scale bars (A, D, G, and J) represent 50 ms. Vertical scale bars in (A, D, G, and J) correspond to 0.5 nA (bars next to current pulses) and 20 mV (bars next to lowest voltage traces. In (B, E, H, and K), horizontal bars represent 1 ms and vertical bars 20 mV.
