Coupling Effects of Cross-Corticomuscular Association during Object Manipulation Tasks on Different Haptic Sensations

The effects of corticomuscular connectivity during object manipulation tasks with different haptic sensations have not been quantitatively investigated. Connectivity analyses enable the study cortical and muscle responses movements, revealing communication pathways between brain muscles. This aims to examine three Electroencephalography (EEG) channels five muscles involving contact surfaces Sandpaper, Suede, Silk. included 12 healthy subjects performing their right hand. Power-Based (PBC) Mutual Information (MI) measures were utilized evaluate significant differences in surfaces, EEG channels, muscles, frequency bands. research yielded following findings: Suede surface exhibited higher connectivity; Mu Gamma bands exerted greater influence; was observed (C3, Cz, C4) Anterior Deltoid (AD) Brachioradialis (B) muscles; primarily involved active movement AD compared resting state. These findings suggest potential implementation motor rehabilitation for more complex movements using novel alternative training systems high effectiveness.
