Abstract

This study builds on our previous work to investigate brain activity just before a voluntary movement. Our novel analytical approach treats neural signals as time series characterized by structural discontinuities. We demonstrate that multiple neural populations synchronize oscillatory transitions exactly with voluntary finger jerk. The precise synchronization between oscillation switches in large cortical populations and movement onset, presents a remarkable finding. The brain appears to maintain an internal temporal framework that accounts for physiological delays, enabling accurate prediction and coordination of motor actions. This mechanism is particularly crucial for orchestrating complex multi-limb movements, where precise central timing must compensate for varying peripheral conduction times.
