The Center for Brain and Health (CBH) was delighted to host the first seminar of this academic year (2024/2025) with the guest speaker Dr Mohamed Ameen – University of Salzburg, which took place on Tuesday, September 10, 2024, at 4 PM (GST) in C2-329.

Abstract

Electrophysiological signals are composed of oscillatory peaks superimposed on an aperiodic component that decreases with increasing frequency, following a 1/f function. This aperiodic component is quantified by the aperiodic exponent and has been shown to distinguish between sleep stages. In this talk, I will demonstrate how optimizing the parameters for measuring aperiodic neural activity can enhance our understanding of ongoing brain processes during sleep and their temporal dynamics. By analyzing EEG and iEEG data, we expand on previous literature and offer new insights into neural dynamics during sleep, paving the way for a more quantitative approach to assessing aperiodic neural activity.

Bio

Mohamed Ameen, a postdoctoral researcher at the Center for Cognitive Neuroscience Salzburg (CCNS) at the University of Salzburg in Austria. After completing his undergraduate studies in pharmacy, he developed a deep passion for understanding the brain and exploring how it perceives the world. Mohamed Ameen is specialized in studying sensory processing in the brain, particularly in the context of sleep, using various electrophysiological techniques.
