We are thrilled to announce the publication of a paper in Cerebral Cortex by our talented PhD student, Mina Elhamiasl! The paper delves into the developmental trajectories of the EEG dominant rhythm (6 to 9Hz) across infancy, shedding light on crucial aspects of early brain development 🧠.
Using a novel sustained attention task, the authors found that the peak frequency, as measured by Center of Gravity (CoG), experiences a remarkable increase from 6 to 9 to 12 months of age in response to various stimuli such as faces, objects, and baseline conditions.
Furthermore, employing exploratory mass univariate analysis, the team modeled these developmental trajectories over occipital, frontal, and central regions, unraveling crucial patterns in early brain activity.
One of the most intriguing findings was the high reliability observed between CoGs in face, object, and baseline conditions across all electrodes. Notably, the developmental increase in CoG proved more reliable than measures of mode frequency across different conditions, highlighting its significance as a robust index of brain development throughout infancy.
Congratulations to Mina Elhamiasl and the entire team for this remarkable achievement! 🎉🔬
