Neurons in the primate extrastriate cortex are highly selective for complex stimulus features
such as faces, objects, and motion patterns. One explanation for this selectivity is that …

Although spatial and feature attention have differing effects on neuronal responses in visual
cortex, it remains unclear why. Response normalization has been implicated in both types of …

The consequences of visual decline in aging have a fundamental and wide-reaching impact
on age-related quality of life. It is of concern therefore that evidence suggests that normal …

When the contrast of an image flickers as it moves, humans perceive an illusory reversal in
the direction of motion. This classic illusion, called reverse-phi motion, has been well …

Locomotor movements cause visual images to be displaced across the eye, a retinal slip
that is counteracted by stabilizing reflexes in many animals. In insects, optomotor turning …

Eye movements are often directed toward stimuli with specific features. Decades of
neurophysiological research has determined that this behavior is subserved by a feature …

The primate visual system is arranged hierarchically, starting from the retina and continuing
through a series of extrastriate visual areas. Selectivity for motion is first found in individual …

We examined how spatially directed attention affected the integration of motion in neurons of
the middle temporal (MT) area of visual cortex. We recorded from single MT neurons while …

We used two-dimensional (2-D) sparse noise to map simultaneous and sequential two-spot
interactions in simple and complex direction-selective cells in macaque V1. Sequential …

The motion response properties of neurons increase in complexity as one moves from
primary visual cortex (V1), up to higher cortical areas such as the middle temporal (MT) and …
