hn candidates and intrinsic properties. The hn candidates all have isolated frequencies within the range of 0.5717 ± 0.01 Hz. The set of 143 individual neurons spans ionic conductance space in a V-formation. A, hn candidate duty cycles spanned the range of 4.27% to 52.7%. B, The peak voltages are the mean supra-threshold oscillation peak voltages and these ranged from 0.7132 to 69.5211 mV. C, The first two panels are two-dimensional plots of duty cycles containing the same data as A. A histogram for hn candidate duty cycles (right); mean duty cycle is 21.33%, standard deviation 11.24. D, One-dimensional plots for peak voltages as function of individual hn conductances (left) make the correlations in B more apparent. These are further summarized in the middle plot showing the relationships between the three conductances and the peak voltages of the hn candidates with regression lines. Right, Histogram for hn candidate peak voltages; mean of peak voltages is 36.2955 mV, standard deviation 17.8493 mV.
