q2 i? The right hemisphere showed greater sensitivity to stage differences, while the left hemisphere differentiated more between task types within the same stage. → Hui Xie 2025

q2 · i? · associational · r1

Topographic hemisphere-wise comparisons of EEG relative PSD across the semester-long study. The authors interpret that "the right hemisphere showed greater temporal sensitivity across different task stages" in alpha and high-beta bands.

"The right hemisphere showed greater temporal sensitivity across different task stages, particularly in the alpha and high-beta bands"
