The Influence of Preceding Movements on Motor Cortical Activity in Finger-Tapping

Introduction: Brain-computer interfaces (BCI) enable the control of external devices via EEG signals, possibly substituting the brain's normal output pathways in paralysed patients. One key problem is the still limited information transfer. This could be improved by increasing the rate of BCI commands; however, a faster command rate might be restricted eventually by the refractory behavior of EEG features commonly used in non-invasive BCI β paradigms, such as event-related desynchronizations (ERD) of pericentral µ rhythms or lateralized readiness potentials (LRP). Objective: We conducted a study in healthy subje…
