Sinusoidal smooth pursuit eye tracking at different stimulus frequencies: position error and velocity error before catch-up saccades in schizophrenia and in major depressive disorder.

30 Aug 2009 OBJECTIVE: The aim of the present study was to ascertain the extent of impairment of position error and velocity error processing in eye tracking dysfunction in schizophrenic and depressive patients. METHOD: A total of 21 schizophrenic and 19 ... Read more...

Visuospatial working memory deficits and visual pursuit impairments are not directly related in schizophrenia.

30 Jul 2009 OBJECTIVE: Patients with schizophrenia show deficits in visuospatial working memory and visual pursuit processes. It is currently unclear, however, whether both impairments are related to a common neuropathological origin. The purpose of the present ... Read more...

Target selection by the frontal cortex during coordinated saccadic and smooth pursuit eye movements.

30 Jul 2009 Oculomotor tracking of moving objects is an important component of visually based cognition and planning. Such tracking is achieved by a combination of saccades and smooth-pursuit eye movements. In particular, the saccadic and smooth-pursuit systems ... Read more...
