+\section*{Analysis of insect photoreceptor data.}
+In this project you will analyse data from intracellular recordings of
+a fly photoreceptor. A R~1--6 photoreceptor was intracellularly
+recorded and was stimulated with a light stimulus.
+
+\begin{questions}
+  \question{} The accompanying dataset (photoreceptor\_data.zip)
+  contains seven mat files. Each of these holds the data from one
+  stimulus intensity. In each file are three variables.  (i)
+  \textit{voltage} a matrix with the recorded membrane potential from
+  10 consecutive trials, (ii) \textit{time} a matrix with the
+  time-axis for each trial, and (iii) \textit{trace\_meta} a structure
+  that stores several metadata. This is the place where you find the
+  \emph{amplitude}, that is the voltage that drives the light
+  stimulus, i.e. the light-intensity.
+  
+  \begin{parts}
+    \part{} Create a plot of the raw data. Plot the average response as
+    a function of time. This plot should also show the
+    across-trial variability.\\[0.5ex]
+    \part{} You will notice that the responses have three main parts, a
+    pre-stimulus phase, the phase in which the light was on, and finally a
+    post-stimulus time. Create an characteristic curve that plots the
+    response strength as a function of the stimulus intensity for the ``onset''
+    and the ``steady state'' phases.\\[0.5ex] 
+    \part{} You may also decide to analyze the post-stimulus response in some
+    more detail.
+  \end{parts}
