EEG Dataset of Healthy Controls and Stroke Patients During Multimodal Tactile-Motor Stimulation

The recordings were obtained during three sensorimotor task conditions designed to examine neural responses to multimodal tactile-motor stimulation: vibration stimulation, active finger bending, and their combination.The EEG signals were recorded at a sampling rate of 1024 Hz using a 128-channel cap arranged according to the international 10-05 system.

Mechanical vibration was delivered to the right hand using a custom-designed vibrating glove. In healthy participants, five stimulation frequencies (15, 40, 80, 120, and 200 Hz) were tested for alpha-band ERD/ERS-based frequency screening, and 40 Hz was used as the standardized vibration frequency in the subsequent comparative paradigm.This dataset supports analyses of cortical activation and brain network dynamics under unimodal and multimodal stimulation, including ERD/ERS analysis, phase lag index (PLI)-based functional connectivity analysis, and EEG microstate analysis.
