Independence of movement preparation and movement initiation
AM Haith, J Pakpoor, JW Krakauer - Journal of Neuroscience, 2016 - Soc Neuroscience
Initiating a movement in response to a visual stimulus takes significantly longer than might
be expected on the basis of neural transmission delays, but it is unclear why. In a visually …
