The light was filtered by a dichroic filter that limited the camera's spectral sensitivity to a range of 480 to 550 nm, matching, to some extent, the spectral sensitivity of the visual motion pathway of flies (Stavenga, 2002).
Neveu et al. suggested that abnormal eye movements change the structure of visual information entering the system, which therefore disrupts the ability of the motion pathways to form normally.
These four families tested 1) face modulation of the motion pathway to STS from V5, 2) motion modulation of the face pathway to STS from OFA, 3) motion modulation of the face pathway to STS from OFA, and 4) motion modulation of both face pathways from OFA and FFA.
A hierarchical vision system, inspired by the functional architecture of the cortical motion pathway, to provide motion interpretation and to guide real-time actions in the real-world, is proposed.
Throughout the arc of flexion, the motion pathways were similar for the three simulated active motion protocols employed in this study (p>0.05).
Classic molecular motion simulation techniques, such as Monte Carlo (MC) simulation, generate motion pathways one at a time and spend most of their time in the local minima of the energy landscape defined over a molecular conformation space.
Since form information is mainly processed in the ventral visual pathway, and motion information when not defining a form is mainly processed in the dorsal pathway [14], these findings show that the temporal limit is not a feature of the motion pathway, and may indeed be a characteristic of the ventral form pathway.
(1) A 5-year R01 grant from the National Eye Institute titled "Impact of visual experience on the development of the motion pathway in the ferret". This project will use electrophysiology, two-photon imaging and behavioral experiments in ferrets of different ages to investigate the role of visual experience on the development of neural mechanisms of visual motion processing.
This finding shows that form-selective motion sensitivity in the STS can be explained in terms of modulation of gain control on information flow in the motion pathway, and provides a substantial constraint for theories of the perception of faces and biological motion.
A complete quantization study of neuromorphic robust optical flow architecture is performed, using properties found in the cortical motion pathway.
