Moving objects generate motion information at different scales, which are processed in the visual system with a bank of spatiotemporal frequency channels. It is not known how the brain pools this information to reconstruct object speed and whether this pooling is generic or adaptive; that is, dependent on the behavioral task. We used rich textured motion(More)
It has long been known that rewarding improves performance. However it is unclear whether this is due to high level modulations in the output modules of associated neural systems or due to low level mechanisms favoring more "generous" inputs? Some recent studies suggest that primary sensory areas, including V1 and A1, may form part of the circuitry of(More)
Are sensory estimates formed centrally in the brain and then shared between perceptual and motor pathways or is centrally represented sensory activity decoded independently to drive awareness and action? Questions about the brain's information flow pose a challenge because systems-level estimates of environmental signals are only accessible indirectly as(More)
Estimating object motion within dynamic visual scenes is a critical skill for animals. In primates, this is supported by cortical neurons identified in Primary Visual Cortex (V1) and so called motion areas Middle Temporal (MT) and adjacent Medial Superior Temporal area (MST, which receives MT inputs) of macaques (Van Essen and Maunsell, 1983).

Despite the enduring interest in motion integration, a direct measure of the space-time filter that the brain imposes on a visual scene has been elusive. This is perhaps because of the challenge of estimating a three-dimensional function from perceptual reports in psychophysical tasks. We take a different approach. We exploit the close connection between(More)
