Happy to share a new preprint in which @paulbuerkner.com and I introduce a novel model-based approach for precisely estimating the onset and offset of M/EEG effects!

Foraging in conceptual spaces: hippocampal oscillatory dynamics underlying searching for concepts in memory

How does the brain access stored knowledge? It has been proposed that conceptual search engages neurocognitive processes similar to foraging in physical space. We tested this idea using intracranial E...

Ever since I made a video about Fourier Transforms, one of the most requested topics on the channel has been its close cousin, the Laplace Transform.

I've been having a lot of fun animating a mini-series about this topic, and the main part is now out.

detection d' is generally overestimated, coz we tend to be too lazy to collect the necessary data in order to correct for the unequal variance between target present vs absent distributions. turns out we can do this for free - using reaction times data. so, let's do it~

Although our preprint is framed around M/EEG data, the general approach is equally applicable to other commonly used time-resolved signals (e.g., pupillometry, eye-, finger-, or mouse-tracking, EMG, etc).
