See the tutorial on the Fourier transform for a basic introduction to its use. After doing this tutorial you will be able to: Compute the amplitude and phase of each component frequency of a signal. Explain how the Fourier transform is a projection on to cosine and sine axis of different frequencies. Reason about how this is a rotation of the time based axes.

L., Merriam, E. P. (2025) Orientation maps in mouse superior colliculus explained by population model of non-orientation selective neurons Journal of Neuroscience In press DOI Abstract Mouse superficial superior colliculus (sSC) has been found to have orientation selective maps, suggesting a fundamentally different selectivity than in primate SC. Moreover, orientation selectivity in mouse sSC appears to change with stimulus properties such as size, shap… text/html 2025-08-28T11:00:32-0700 justin (justin@undisclosed.example.com) http://gru.stanford.edu/doku.php/grupub/eyelink?rev=1756404032&do=diff Eyelink libraries You can download eyelink libraries from SR-Research.
