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

This dataset comprises 128-channel EEG recordings from 14 right-handed participants, including 7 healthy controls and 7 patients with clinically confirmed left-hemisphere intracerebral hemorrhagic stroke. 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. It may facilitate studies of sensorimotor integration, stroke-related network reorganization, and the development of EEG-based biomarkers for neurorehabilitation research.All data were collected with informed consent and have been anonymized for sharing and reuse.
