Spike Frequency Adaptation Reduces Neural Ensembles Noise
Abstract:
Spike frequency adaptation is a ubiquitous phenomena which changes the
spiking statistics beyond the renewal descriptions as neurons exhibit
interspike interval correlations due to SFA. In this talk, I shortly
review the experimental evidence accounting for interspike interval
correlations and show in many biophysical and phenomenological models
of SFA, interval serial correlations are coexisting. Additionally, we
investigate the effect of SFA on variability and noise level of the
ensemble spiking activity. Our results show a reduction of the noise
level (Fano factor) in the ensemble rate.
