Homework #1
- Simulate a 10 second spike train assuming a Poisson process with
a rate of 50 Hz. Draw the interspike interval histogram. Compute the
the coefficient of variation. Simulate the same process for 1 second
for 200 different trials and compute the Fano factor
- Repeat the above exercise assuming that when a neuron spikes the
spike rate goes to zero and recovers to 50 Hz with a time constant of
10 msec. Compute the CV and the Fano factor in this case. How do
you expect the CV and the Fano factor to depend on the time constant
of recovery?
- Simulate 30 seconds of a Poisson process whose rate is
sinusoidal with a period of 200 msec.
r(t) = 20 Hz + 25 cos(10 pi t)
Compute the spike-time autocorrelation function. Here is mine
