WebThe appropriate interval can be estimated from the interspike interval distribution, Fig. 4. As in many real neurons, the interval distribution has three main features: a ‘refractory period’ during which spikes are strongly suppressed, a peak at a preferred interval, and an exponential tail. ... Thus although we are using less data, it is ... WebDec 16, 2010 · Channel noise is the dominant intrinsic noise source of neurons causing variability in the timing of action potentials and interspike intervals (ISI). Slow adaptation currents are observed in many cells and strongly shape response properties of neurons. These currents are mediated by finite populati …
