Spiral motion selective neurons in area MSTd contribute to judgments of heading.
Self-motion generates patterns of optic flow on the retina. Neurons in the dorsal part of the medial superior temporal area (MSTd) are selective for these optic flow patterns. It has been shown that neurons in this area that are selective for expanding optic flow fields are involved in heading judgments. We wondered how subpopulations of MSTd neurons, those tuned for expansion, rotation or spir...

31 Self-motion generates patterns of optic flow on the retina. Neurons in area MSTd are 32 selective for these optic flow patterns. It has been shown that neurons in this area that are 33 selective for expanding optic flow fields are involved in heading judgments. We 34 wondered how subpopulations of MSTd neurons – those tuned for expansion, rotation or 35 spiral motion – contribute to heading ...
متن کاملA Unified Model of Heading and Path Perception in Primate MSTd
Self-motion, steering, and obstacle avoidance during navigation in the real world require humans to travel along curved paths. Many perceptual models have been proposed that focus on heading, which specifies the direction of travel along straight paths, but not on path curvature, which humans accurately perceive and is critical to everyday locomotion. In primates, including humans, dorsal media...
متن کاملA neural network model of spiral–planar motion tuning in MSTd
Neurophysiological studies in MSTd report the existence of motion pattern selective cells whose visual motion properties span a continuum of values, suggesting a role in estimates of self-motion from optic flow. Biologically motivated models of heading estimation support this view, having identified similar visual motion properties within their "neural" structures. While such models have addres...
متن کاملConstrained-Path Discovery by Selective Diffusion
The demand for live and interactive multimedia services over the Internet raises questions on how well the Internet Protocol (IP)’s best-effort effort service can be adapted to provide adequate end-to-end quality of service (QoS) for the users. Although the Internet community has developed two different IP-based QoS architectures, neither has been widely deployed. Overlay networks are seen as a...
