New paper out! We show that EEG biomarkers interact in opposite ways in Alzheimer’s disease (AD) vs. epilepsy. This could explain why epileptiform activity is inconsistently seen in AD—and highlights the need for wideband EEG to uncover these dynamics. #HFOnews

To test the hypothesis that high-frequency oscillations (HFOs) between 250 and 500 Hz occur in mouse models of Alzheimer's disease (AD) and thus are not unique to epilepsy.
