The researchers collected the brain activity — five additional sensors were
placed on the volunteers» faces to allow researchers to screen for the impact of
random movement, including eye blinks — and then
mapped the signals back to the brain to determine how specific parts of the brain are involved in discrete tasks associated with walking, said Trieu Phat Luu, co-first author and a post-doctoral researcher in the Noninvasive Brain - Machine Interface System Laboratory at UH.
