Mitral cell diversity is conferred in part by a 4-aminopyradine (4-AP)-sensitive potassium channel. A and C: spike responses to DC current from 2 recorded mitral cells in the control condition (A) and with the addition of 4-AP (C). B and D: interspike interval histograms for the cells in control condition (B) and with the addition of 4-AP (D). E: population coefficient of variation in the interspike intervals (CVisi) show a decrease in the distribution of CVisi with the addition of 4-AP. F and G: firing rate/current (F/I) relationship for the 2 cells in A.
