\begin{questions}
|
|
\question The accompanying data {\tt Neuron22.mat} stores a single
|
|
data matrix {\tt data\_unsorted} containing spikes from a neuron in
|
|
macaque prefrontal cortex (data courtesy of Prof. Nieder). The task
|
|
of the monkey was to discriminate point-sets with 1 to 4 points. The
|
|
first column contains the number of points shown plus one. The
|
|
remaining columns contain the spike response across 1300\,ms. During
|
|
the first 500\,ms the monkey was fixating a target. The next 800\,ms the
|
|
stimulus was shown. This was followed by 1000\,ms delay time before
|
|
the monkey was allowed to respond.
|
|
|
|
\begin{parts}
|
|
\part Plot the data in an appropriate way.
|
|
\part Sort the trials according to the stimulus presented and
|
|
compute the firing rate (in Hz) in the time interval
|
|
500-1300\,ms. Plot the firing rate in an appropriate way.
|
|
\part Use an appropriate test to determine whether the firing rate
|
|
in that interval is significantly different for 1 vs. 4 points
|
|
shown.
