\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 1300ms. During
  the first 500ms the monkey was fixating a target. The next 800ms the
  stimulus was shown. This was followed by 1000ms 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
    500-1300ms. 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.
  \end{parts}
