Abstract

Changes in cortical signals related to motor planning processes have been widely studied in the past. However, no studies so far have investigated the intra-subject differences in these signals between analytical and coordinated upper limb and lower limb cue-based movements. Here, data from healthy subjects is analyzed to research this aspect. The statistical analysis carried out with data from 7 subjects indicates that statistically significant differences were observed between premotor cortical activities of upper and lower limb movements. Specifically, higher amplitudes of the contingent negative variation pattern were observed for lower-limb tasks. Such results may be due to complexity in movement task planning. BCI devices could take advantage and be improved with the knowledge provided.
