No evidence for impulsivity in the antisaccade task under STN-DBS
reduction of antisaccade latency
Stimulation with 130 Hz- and 60 Hz-pulses led to a reduction of antisaccade latency which is in line with previous studies investigating the effect of DBS on the antisaccade task without considering the pulse frequency (The effect of DBS on latencies was opposing with correct antisaccades (reduced) and reflexive prosaccade errors (increased). Thus, STN-DBS may thus result in specific promotion of voluntary actions (a correct antisaccade) accompanied by a deceleration of the reflexive response (a prosaccade error) rather than a general acceleration of saccade initiation. This result opposes previous findings supporting increased motor impulsivity with STN-DBS (
