Table 1Comparison of Basic Electrophysiological Properties of MB Cells and FS Cells
Main firing frequency, resting membrane potential (Vm), and threshold potential were significantly different in MB cells and FS cells (**p < 0.0001; *p < 0.001, n = 11 for each measurement). AHP: afterhyperpolarization. Firing properties were analyzed upon the same current injection for both cell types. Stimulus intensity was 500 pA and was sufficient to drive regular firing of FS cells during the entire time of current injection (1 s).
