Background:

Electroencephalography (EEG) signal analysis for motor imagery decoding faces challenges due to feature redundancy and poor geometric representation caused by volume conduction.
Traditional methods often overlook the intrinsic manifold geometric properties of EEG signals and struggle with dynamic cross-domain feature dependencies.

Purpose of the Study:

To propose a novel spatiotemporal dynamic attention fusion network grounded in Riemannian manifolds (ST-MA-SENet) for improved EEG motor imagery decoding.
To address the limitations of existing models in handling feature redundancy and capturing dynamic cross-domain dependencies.

Main Methods:

Developed ST-MA-SENet, a network that assesses spatiotemporal correlations in both Euclidean and Riemannian spaces.

Keywords:

Electroencephalography Motor imagery decoding Riemannian space Spatiotemporal features
