In this project you have to quantify the strength of this -coulpling using the \textbf{vector strength}: -\begin{equation} - VS = \sqrt{\left(\frac{1}{n}\sum_{i=1}^{n}cos - \alpha_i\right)^2 + \left(\frac{1}{n}\sum_{i = 1}^{n} sin \alpha_i - \right)^2}, -\end{equation} -with $n$ the number of spikes and $\alpha_i$ the timing of the each -spike expressed as the phase relative to the EOD. The vector strength -varies between $0$ and $1$ for no phase locking to perfect phase -locking, respectively. - -\begin{questions} - \question In the accompanying datasets you find recrordings of the - ``baseline'' activity of P-unit electrorecptors of different weakly - electric fish of the species \textit{Apteronotus leptorhynchus}. - The files further contain respective recordings of the \textit{eod}, - i.e. the fish's field. - \begin{parts} - \part Plot an average of the single EOD cylces of each fish - together with an respective PSTH. - \part Implement a function that estimates the vector strength - between the \textit{eod} and the spikes. - \part Create a polar plot that shows the timing of the spikes - relatve to the EOD. - \part Analyze the baseline responses of each fish and extract - measures from them as you have done in week 3. Plot the results - appropriately. - \end{parts} -\end{questions} - -\end{document}
