\begin{questions}
|
|
\question The accompanying file contains ten stimulus and response
|
|
sequences of a P-Unit of a weakly electric fish {\em Apteronotus
|
|
leptorhynchus}. Another matrix contains the corresponding {\em
|
|
electric organ discharge (EOD)} of the fish. The sampling rate is
|
|
100kHz.
|
|
\begin{parts}
|
|
\part Split the data in non-overlapping 200ms windows and plot
|
|
them in an appropriate way.
|
|
\part Compute the autocorrelation of the spike response as well as
|
|
the cross-correlation between stimulus and spike response.
|
|
\part Determine the fundamental stimulus frequency and the EOD
|
|
frequency using a Fourier transform.
|
|
\part Convolve the spike responses (windows) with a Gaussian of
|
|
appropriate size and compute the average Fourier amplitude
|
|
spectrum of the spike response. Plot the result in an appropriate
|
|
way.
|
|
\part Determine whether you can find peas in the amplitude
|
|
spectrum at the fundamental frequency of the EOD and/or the
|
|
stimulus and/or their difference.
