How Noisy Adaptation of Neurons Shapes Interspike Interval Histograms and Correlations

Illustration of the deterministic dynamics of the adaptive PIF neuron.
The flow in the phase space spanned by possesses a stable limit cycle, which consists of the voltage drift from
at
to the threshold (A), the following increase of
by an amount
(B) and the subsequent voltage reset (C). The period of the limit cycle
is solely due to the time of the process A, whereas the processes B and C occur instantaneously. A trajectory starting off the limit cycle at
reaches the threshold at the time
. The deviation from
after one period has an absolute magnitude
.
