Precise temporal localisation of M/EEG effects with Bayesian generalised additive multilevel models
Time-resolved electrophysiological measurements such as those obtained through magneto- and electroencephalography (M/EEG) offer a unique window onto the neural activity underlying cognitive processes...

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!

In a brief paper last year, we used Beethoven's genome to directly illustrate the fallacies involved.🧪👇
