Volume-Wise Task fMRI Decoding with Deep Learning:Enhancing Temporal Resolution and Cognitive Function Analysis

In recent years,the application of deep learning in task functional Magnetic Resonance Imaging (tfMRI) decoding has led to significantthis http URL,most studies remain constrained by assumption of temporal stationarity in neural activity,resulting in predominantly block-wise analysis with limited temporal resolution on the order of tens ofthis http URLlimitation restricts the ability to decode cognitive functions inthis http URLaddress these limitations, this study proposes a deep neural network designed for volume-wise identification of task states within tfMRI data,thereby overcoming the constraints of conventionalthis http URLon Human Connectome Project (HCP) motor and gambling tfMRI datasets,the model achieved impressive mean accuracy rates of 94.0% and 79.6%,this http URLresults demonstrate a substantial enhancement in temporal resolution,enabling more detailed exploration of cognitivethis http URLstudy further employs visualization algorithms to investigate dynamic brain mappings during different tasks,marking a significant step forward in deep learning-based frame-level tfMRIthis http URLapproach offers new methodologies and tools for examining dynamic changes in brain activities and understanding the underlying cognitive mechanisms.
