Antisaccade: looking away from a target opposite direction. Instead of looking at the target, participants must look in the. It is a complex task for humans and monkeys to perform. You must supress the involuntary urge to perform a prosaccade: response suppression (inhibit prosaccade, visual vector inversion, looking away (time consuming and cognitive) Overlap paradigm: sees fixation cross and the target appeared: fixation cross is always there, fixation neurons fixate on the cross locking eyes on the fixation point. Antisaccades always have longer reaction times than overlap. Gap antisaccades have shorter reaction times that overlap: there are a lot of directional errors. Used for someone who has mental disorders (schizophrenia: fewer directional errors show the effectiveness of medication/treatment. Prosaccade information goes to the retina striate to the si. Which then goes to the reticular formation (alpha motor. Schematic of human visual system (exam question) Direct pathway: via the retinotectal pathway neurons) that directly move eye.
