Abstract

While functional magnetic resonance imaging (fMRI) offers rich spatial resolution, it is limited by high operational costs and significant infrastructural demands. In contrast, electroencephalography (EEG) provides millisecond-level precision in capturing electrical activity but lacks the spatial resolution necessary for precise neural localization. To bridge these gaps, we introduce E2fNet, a simple yet effective deep learning model for synthesizing fMRI images from low-cost EEG data. E2fNet is specifically designed to capture and translate meaningful features from EEG across electrode channels into accurate fMRI representations. Extensive evaluations across three datasets demonstrate that E2fNet consistently outperforms existing methods, achieving state-of-the-art results in terms of the structural similarity index measure (SSIM). Our findings suggest that E2fNet is a promising, cost-effective solution for enhancing neuroimaging capabilities. The code is available at https://github.com/kgr20/E2fNet.
