Addressing Confounds in Functional Connectivity Analyses of Calcium Imaging

Dingding Ye, Charan Santhirasegaran, Ryan Pai, Genevera I. Allen, Joseph Young

ICASSP 2024accepted

Elucidating functional connectivity reveals interactions between brain regions based on their in vivo activity. However, a gap exists in current statistical methods’ ability to untangle direct interactions from confounding activity due to stimuli and physiological effects, leading to a bottleneck in…

MindEye2: Shared-Subject Models Enable fMRI-To-Image With 1 Hour of Data

Paul Steven Scotti, Mihir Tripathy, Cesar Torrico, Reese Kneeland, Tong Chen, Ashutosh Narang +5

ICML 2024poster

Reconstructions of visual perception from brain activity have improved tremendously, but the practical utility of such methods has been limited. This is because such models are trained independently per subject where each subject requires dozens of hours of expensive fMRI training data to attain hig…
