Motor Psychophysics
We have built a setup from scratch to study visuomotor adaptation during reaching. This consists of a glass table where subjects where subjects rest their arm through a support with two airsleds, a digital camera located underneath the table, which captures the hand movement, a computer monitor that displays visual targets and hand movements through a cursor, and a mirror interposed between the table and the monitor, which reflexes the visual display at the height of the eyes, allowing direct spatial mapping between targets and hand.
We study the adaptive response to manipulations of the visual or proprioceptive feedback by introducing optical rotations or mechanical perturbations.
