Neuronal Spike Timing Adaptation Described with a Fractional Leaky Integrate-and-Fire Model
Figure 7
The properties of the voltage-memory trace.
(A–D)The changing response of the memory trace across multiple spikes, = 0.2. (A) Voltage trace of the fractional model stimulated with
nA. Spikes have been clipped to emphasize the sub-threshold dynamics. (B)
for the data in A. (C) The memory trace for the data in A. (D) Overlapped memory traces for different inter-spike intervals during the same simulation. (E–G) The dynamics of the weight of the voltage-memory trace
and the fractional coefficient depend on the fractional exponent
. (E) When
decreases the weights increase. (F) The value of the weight
as a function of
and time. (G) The fractional coefficient of the Markov process
increases when
is decreased.
