Neurophysiological studies in non-human primates have identified saccade-related neuronal activity in cortical regions including frontal (FEF), supplementary (SEF) and parietal eye fields. Lesion and neuroimaging studies suggest a generally homologous mapping of the oculomotor system in humans; however, a detailed mapping of the precise anatomical location(More)
High-field (3 Tesla) functional magnetic resonance imaging (MRI) was used to investigate the cortical circuitry subserving pursuit tracking in humans and compare it to that for saccadic eye movements. Pursuit performance, relative to visual fixation, elicited activation in three areas known to contribute to eye movements in humans and in nonhuman primates:(More)
Growing access to large-scale longitudinal structural neuroimaging data has fundamentally altered our understanding of cortical development en route to human adulthood, with consequences for basic science, medicine, and public policy. In striking contrast, basic anatomical development of subcortical structures such as the striatum, pallidum, and thalamus(More)
A critical technique for understanding how neuronal activity contributes to behavior is determining whether perturbing it changes behavior. The advent of optogenetic techniques allows the immediately reversible alteration of neuronal activity in contrast to chemical approaches lasting minutes to hours. Modification of behavior using optogenetics has had(More)
The idea of a second visual pathway, in which visual signals travel from brainstem to cortex via the pulvinar thalamus, has had considerable influence as an alternative to the primary geniculo-striate pathway. Existence of this second pathway in primates, however, is not well established. A major question centers on whether the pulvinar acts as a relay,(More)
Changes in frontostriatal systems are believed to reduce the efficiency of executive cognitive functions during normal aging, especially the inhibitory control of attentional and behavioral responses. To characterize changes during normal aging in sensorimotor, working memory and inhibitory attentional systems, we tested 20 healthy elderly subjects (age(More)
How our vision remains stable in spite of the interruptions produced by saccadic eye movements has been a repeatedly revisited perceptual puzzle. The major hypothesis is that a corollary discharge (CD) or efference copy signal provides information that the eye has moved, and this information is used to compensate for the motion. There has been progress in(More)
Visual perception results from the interaction of incoming sensory signals and top down cognitive and motor signals. Here we focus on the representation of attended locations in parietal cortex and in earlier visual cortical areas. We review evidence that these spatial representations are modulated not only by selective attention but also by the intention(More)
Active vision requires the integration of information coming from the retina with that generated internally within the brain, especially by saccadic eye movements. Just as visual information reaches cortex via the lateral geniculate nucleus of the thalamus, this internal information reaches the cerebral cortex through other higher-order nuclei of the(More)
Behavioral and physiological studies have established that visual attention to a given feature or location can modulate early visual processing. In the present experiment, we asked whether auditory attention can likewise influence visual processing. We used a visual illusion, the motion aftereffect (MAE), to assess the effects of visual and auditory(More)
