Cerebellar Transcranial Direct Current Stimulation Effects on Saccade Adaptation

Table 1

Saccadic gains, kinematics, adaptation gain-change, and retention. Gains, saccade kinematics (peak velocity and duration) measured during the three phases for inward and outward adaptation in the two conditions. Inward and outward adaptation gain-change for the two conditions shows the difference between preadaptation and adaptation phases. Adaptation phase values are the last ten trials (adaptation gain). Peak velocity in deg/s and Duration in ms.
