- Multiplexing in the primate motion pathwayAlexander C Huk
Center for Perceptual Systems, Neurobiology, Psychology, The University of Texas at Austin, TX 78712, United States
Vision Res 62:173-80. 2012..In addition to providing a fresh perspective on how successive stages of visual processing might be approached, multiplexing also raises caveats about the value of "neural correlates" for understanding neural computation...
- Neural activity in macaque parietal cortex reflects temporal integration of visual motion signals during perceptual decision makingAlexander C Huk
Center for Perceptual Systems, Department of Psychology, University of Texas, Austin, Texas 78712, USA
J Neurosci 25:10420-36. 2005..Temporal integration may be a fundamental computation underlying higher cognitive functions that are dissociated from immediate sensory inputs or motor outputs...
- Visual neuroscience: retinotopy meets percept-otopy?Alexander C Huk
Neurobiology and Center for Perceptual Systems, The University of Texas at Austin, Austin, TX 78715, USA
Curr Biol 18:R1005-7. 2008..A new study suggests that the representations on this map are affected by visual illusions that alter perceived size. Spatial patterns of activity may thus reflect perceived size...
- Speed and eccentricity tuning reveal a central role for the velocity-based cue to 3D visual motionThaddeus B Czuba
The University of Texas at Austin, Section of Neurobiology, Center for Perceptual Systems, Department of Psychology, Austin, TX 78712, USA
J Neurophysiol 104:2886-99. 2010..These results suggest that for direction discrimination outside the fovea, 3D motion perception primarily relies on the velocity-based cue with little, if any, contribution from the disparity-based cue...
- Disparity- and velocity-based signals for three-dimensional motion perception in human MT+Bas Rokers
Neurobiology, Psychology, Center for Perceptual Systems, Institute for Neuroscience, and Imaging Research Center, The University of Texas at Austin, Austin, Texas, USA
Nat Neurosci 12:1050-5. 2009..Our results indicate that MT+ carries critical binocular signals for three-dimensional motion processing, revealing an important and previously overlooked role for this well-studied brain area...
- Quantifying spatial uncertainty of visual area boundaries in neuroimaging dataDean Kirson
Section of Neurobiology, Center for Perceptual Systems, Imaging Research Center, and Institute for Neuroscience, The University of Texas at Austin, Austin, TX 78712, USA
J Vis 8:10.1-15. 2008..This approach provides a general, unbiased arena for evaluating: (1) competing conceptions of visual area organization; (2) analysis technique efficacy; and (3) data quality...
- Strong percepts of motion through depth without strong percepts of position in depthBas Rokers
Neurobiology, Center for Perceptual Systems, Institute for Neuroscience, and Imaging Research Center, The University of Texas at Austin, Austin, TX 78712, USA
J Vis 8:6.1-10. 2008....
- The effect of stimulus strength on the speed and accuracy of a perceptual decisionJohn Palmer
Department of Psychology, University of Washington, Seattle, WA, USA
J Vis 5:376-404. 2005..The theory's analytic chronometric function allows one to extend theories of accuracy to response time...
- Retinotopy and functional subdivision of human areas MT and MSTAlexander C Huk
Department of Psychology, Stanford University, Stanford, California 94305 2130, USA
J Neurosci 22:7195-205. 2002..Putative human MT and MST were typically located on the posterior/ventral and anterior/dorsal banks of a dorsal/posterior limb of the inferior temporal sulcus, similar to their relative positions in the macaque superior temporal sulcus...
- A motion aftereffect from still photographs depicting motionJonathan Winawer
Stanford University, Psychology Department, Stanford, CA 94305, USA
Psychol Sci 19:276-83. 2008..The transfer of adaptation from motion depicted in photographs to real motion demonstrates that the perception of implied motion activates direction-selective circuits that are also involved in processing real motion...
- Pattern-motion responses in human visual cortexAlexander C Huk
Psychology Department, Stanford University, Stanford, California 94305 2130, USA
Nat Neurosci 5:72-5. 2002..Reducing the perceptual coherence of the plaids yielded a corresponding decrease in pattern-motion responsivity, providing evidence that percepts of coherent motion are closely linked to the activity of pattern-motion cells in human MT+...
