Cerebellar Transcranial Direct Current Stimulation Effects on Saccade Adaptation

Figure 3

Saccade kinematics for sham and tDCS conditions. Left panel shows inward adaptation experiment and right outward adaptation experiment. (a) Peak velocity evolution throughout the trials as median values for all the subjects. Line on the top depicts blocks composed of the median values of 10 trials. For inward adaptation (left) a clear reduction of the velocity is observed as gains become smaller, not present in the same way for the increasing gains in outward adaptation (right). (b) Saccade durations as median values for all subjects. Line on the top depicts blocks composed of the median values of 10 trials. On the left, saccade durations become slightly smaller as gains become smaller. On the right, saccade durations increase as the task evolves as a result of saccade lengthening.
