Gamma coherence mediates interhemispheric integration during multiple object tracking
Nicholas S. Bland, Jason B. Mattingley, Martin V. Sale
Abstract
Using a multiple object tracking paradigm, we were able to manipulate the need for interhemispheric integration on a per-trial basis, while also having an objective measure of integration efficacy (i.e., tracking performance). We show that tracking performance reflects a cost of integration, which correlates with individual differences in interhemispheric EEG coherence. Gamma coherence appears to uniquely benefit between-hemifield tracking, predicting performance both across participants and across trials.
