Adaptive control of movement deceleration during saccades
Fig 2
In Experiment 1, adapted saccades arrive at an endpoint with a trajectory that is quite different from control saccades that arrive at the same endpoint.
A. Horizontal velocity of control saccades and adapted saccades. In control trials, targets are presented at (+1o,15o), (+2o,15o), and (+3o,15o). In adapted saccades, the same endpoint is achieved but through learning. Adapted saccades exhibit a smaller horizontal displacement during the acceleration period, but a larger displacement during the deceleration period (with respect to baseline). B. Control saccade have roughly equal horizontal displacement for the acceleration and deceleration period commands. In comparison, an adapted saccade has most of its horizontal displacement due to the deceleration period commands. Error bars are between subject SEM.
