%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Audrey Effenberger % MCB 105: Systems Neuroscience % DA 10: Auto- and cross-correlation % % In this script, I acquire mouse sniffing and olfactory bulb spiking data, % which I then auto- and cross-correlate to identify the relationship % between the two. % % Based on my autocorrelogram, I would say that there's a slight weak % periodicity in sniffing. The plot shows a regular oscillatory pattern of % positive, no, and negative correlation. Though the magnitude is very % small, the pattern is very regular. This confirms my assumptions that % sniffing is a normal behavior that is performed continually. % % The cross-correlation of sniffing and spike rate shows no significant % pattern or periodicity. Using find() and max(), I identified the peak to % be 0.06186. This makes physiological sense, because I would expect spike % rate to increase immediately after sniffing. The slight delay probably % comes from the fact that neuronal signal conduction isn't instantaneous.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
