EEG Signal Synchronization Patterns During Hand Laterality Judgment Task

EasyChair Preprint 9870

Abstract

Motor imagery is a mental stimulation that triggers oscillatory events in sensorimotor rhythms often used in brain-computer interface applications, as well as a stimulus used to understand brain activity and improve the rehabilitation process of spinal cord injury people. Using the data extracted from an electronic game designed for a rehabilitation purpose, this paper describes the steps to extract the EEG synchronization patterns during the Hand Laterality Judgment Task that stimulates motor imagery processes, i.e., implicit motor imagery. As result, we obtained the curves of synchronization, in dB values, that showed different levels of synchronization between alpha and beta bands and an activity mostly distributed over centro-parietal and parietal regions.

Keyphrases: ERD/ERS, Hand Laterality, mental rotation
