Corticospinal properties are associated with sensorimotor performance in action video game players

Notwithstanding the apparent demands regarding fine motor skills that are required to perform in action video games, nervous system of players has not been studied systematically. In present study, we hypothesized find differences sensorimotor performance and corticospinal characteristics between game (Players) Controls. We tested games tasks used transcranial magnetic stimulation (TMS) measure map, input-output (IO) short intra-cortical inhibition (SICI) curves first dorsal interosseous (FDI) muscle Players (n = 18) Control 18). scored higher tests had stronger SICI evoked potential (MEP) amplitudes. Multiple linear regressions showed differed with respect their relation reaction time excitability. However, did different map topography or IO for when compared Action an increased efficiency cortical inhibitory excitatory neural networks. also a MEPs time. The study demonstrates as ideal population mechanisms underlying visuomotor learning.
