Subtypes of human neocortical FS neurons. (A–C) Example V_m traces from c-FS (A), b-FS (B), and d-FS (C) neurons in response to supra-threshold current steps (500 ms in duration). Bottom traces are expanded view of the first (solid line) and last (dashed line) APs in a train and are in the same scale. (D) Comparison of adaptation ratio between human fast-spiking neuronal types. (E) F-I curves of all three types of human fast-spiking neurons. (F) Comparison of initial F-I slope between human fast-spiking neuronal types. The circles in box-whisker plots are the maximal outliers. ^***, p < 0.005, Wilcoxon rank sum test.
