OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected to start before the end of Hilary Term to allow all future events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed on the Staff Gateway and via email to identified OxTalks users.
If you have any questions, please contact halo@digital.ox.ac.uk
Many statistical methods commonly used in neuroscience are invalid, and can lead to incorrect conclusions inferred with high levels of statistical significance. This is because traditional methods assume independence of samples, which is not the case for neurophysiological signals with slow continuous trends over time. I will discuss how to spot this problem of “nonsense correlations”, and describe a suite of statistical tests that can be validly used with slowly-drifting neurophysiological data. I will also discuss how to design behavioral paradigms that allow a wider range of valid tests for analysis of brain recordings.
