Regularity of the firing pattern of spontaneously active PNC cells. A, Current clamp recording from a PNC cell at slightly depolarized membrane potential. B, The interspike interval histogram shows a narrow Gaussian distribution with only little variation of interspike intervals. C, The regularity of the firing can also be derived from the autocorrelogram which exhibits multiple equally spaced peaks due to the little variation in the interspike intervals.
