Decoding of two hand grasping types from EEG

Introduction: Arm and hand movements are essential for performing activities of daily living (ADL). As a result, people with severe motor disabilities would greatly benefit from hand neuroprostheses for restoring grasping capabilities. Non-invasive prostheses mostly rely on EEG correlates of reaching, such as anticipatory potentials for movement initiation [1] or sensorimotor rhythms for movement execution [2]. In this work, we report EEG correlates for two different grasping types and the feasibility of performing reliable detection in single trials.
