Abstract: 
Humans use smooth pursuit eye movements to track moving objects of interest In order to track an object accurately motion signals from the target have to be integrated and segmented from motion signals in the visual context Most studies on pursuit eye movements used small visual targets against a featureless background disregarding the requirements of our natural visual environment Here we tested the ability of the pursuit and the perceptual system to integrate motion signals across larger areas of the visual field Stimuli were random-dot kinematograms containing a horizontal motion signal which was perturbed by a spatially localized peripheral motion signal Perturbations appeared in a gaze-contingent coordinate system and had a different direction than the main motion including a vertical component We measured pursuit and perceptual direction discrimination decisions and found that both steady-state pursuit and perception were influenced most by perturbation angles close to that of the main motion signal and only in regions close to the center of gaze The narrow direction bandwidth (26 angular degrees full width at half height) and small spatial extent (8 degrees of visual angle standard deviation) correspond closely to tuning parameters of neurons in the middle temporal area (MT) (C) 2010 Elsevier Ltd All rights reserved
