Functionally annotated electrophysiological neuromarkers of healthy ageing and memory function. [PDF]

Hum Brain Mapp
We analysed a large open resting‐state EEG dataset and found that dynamic rather than static neuromarkers better capture cognitive ageing. We clarified that individualised alpha power reflects memory performance rather than ageing. Finally, we used functionally annotated source reconstruction to reveal domain‐specific electrophysiological mechanisms ...

Re‐evaluation of erythritol (E 968) as a food additive

EFSA Journal, Volume 21, Issue 12, December 2023., 2023
Abstract This opinion addresses the re‐evaluation of erythritol (E 968) as food additive and an application for its exemption from the laxative warning label requirement as established under Regulation (EU) No 1169/2011. Erythritol is a polyol obtained by fermentation with Moniliella pollinis BC or Moniliella megachiliensis KW3‐6, followed by ...

Simplest Shapes First! But Let's Use Cognitive Science to Reconceive and Specify What “Simple” Means

Mind, Brain, and Education, Volume 17, Issue 1, Page 5-19, February 2023., 2023
Abstract Children's informal and formal learning experiences with geometric shapes currently result in misconceptions that persist into adulthood. Here, we combine research from mathematics education as well as cognitive science pertaining to concepts, categories, and learning strategies to propose a more optimal progression that is better specified ...
