Key Points

This research investigates whether unilateral lower limb movements exhibit lateralization similar to upper limb movements.
Recorded EEG signals from 15 healthy volunteers during foot-lift tasks under motor execution and motor imagery conditions.
Analyzed event-related potential components and functional connectivity measures to characterize brain activity patterns.
Systematically compared motor imagery with motor execution using the same experimental setup.
Motor imagery of the lower limb produced distinct lateralized neural activity across brain hemispheres.
Confirmed lateralization for lower limb movements comparable to upper limb tasks, supporting the laterality hypothesis.
Findings suggest a shared neural substrate for actual and imagined lower limb movements, relevant for brain-computer interface research.

We only have this paper's title and publication details.

Shows lateralization patterns in lower limb movements, indicating shared neural structures for movement execution and imagery.
