\section*{Reverse reconstruction of the stimulus evoking neuronal responses.}
During the course we have used the Spike-Triggered-Average to
reconstruct the stimulus
\begin{questions}
\question .
\begin{parts}
\part Estimate the STA and plot it for each of the cells.
\part Implement a function that estimates the reconstruction
error using the mean-square-error and express it relative to the
variance of the original stimulus.
\begin{equation}
err = \frac{1}{N} \cdot \displaystyle\sum^{N}_{i=1}(x_i - \bar{x}),
\end{equation}
with $N$ the number of data points, $x_i$ the current value and
$\bar{x}$, the average of all $x$.
\part Analyze the robustness of the reconstruction. Estimate
the STA with less and less data and estimate the reconstruction
error.
\part Plot the reconstruction error as a function of the data
amount used to estimate the STA.
\part Apply the STA estimated for one neuron to reconstruct
the stimulus another neuron has seen.
\end{parts}
