Balance perturbation-evoked cortical N1 responses are larger when stepping and not influenced by motor planning
Aiden M. Payne, Lena H. Ting
Abstract
The cortical N1 response to balance perturbation is larger when executing compensatory steps, suggesting a relationship between the cortical N1 and subsequent motor behavior. Additionally, the cortical N1 response is not impacted by prior planning of the stepping reaction, suggesting that predictability of the motor outcome does not impact the N1 in the same way as predictability of the perturbation stimulus.
