isi.gamma | R Documentation |
The rate approximates mean firing rate, shape is a measure of firing regularity: - for firing in bursts: log(shape) < 1 - for Poisson distributed firing: log(shape) = 1 - for firing with peak of ISI: log(shape) > 1
isi.gamma(spike.train, chunk.length = 100)
spike.train |
vector of spike times |
chunk.length |
length of chunks used for estimation |
Calculation of the measure adopted from: Y. Mochizuki et al., Similarity in neuronal firing regimes across mammalian species. Journal of Neuroscience (2016) in press.
