Effect of subthalamic nucleus deep brain stimulation on visual scanning

Since saccades reflect the activity of the superior colliculus, which receives projections from the basal ganglia, studies on saccades provide insights into the function of basal ganglia in various neurological conditions, including Parkinson's disease (PD) (Terao et al., 2011; Gorges et al., 2014). In fact, many studies have studied the performance of saccades in PD (White et al., 1983; Crawford et al., 1989; Nakamura et al., 1994; Vermersch et al., 1994; Kimmig et al., 2002; Yugeta et al., 2010; Terao et al., 2011; Matsumoto et al., 2011, 2012; Gorges et al., 2014).
