Neural architectures for stereo vision by Parker, A, Smith, J, Krug, K

“…By contrast, in the extrastriate cortical area V5/MT, which has a specialized architecture for stereo depth, the module for representation of stereo is about 1mm in surface extent, so the representation of stereo in V5/MT is more compressed than V1 in terms of neural wiring of the neocortex. …”

Changes in variance of neuronal signals may be perceptually relevant for stereo vision by Cicmil, N, Parker, A, Krug, K

“…These results demonstrate that neurons in a visual area higher in the cortical hierarchy have a greater response variability to anti-correlated stimuli, which do not give rise to a coherent stereo percept. A recurrent cortical network including V5/MT that quenches neural variability may contribute to solving the stereo correspondence problem.…”

The role of single MT (v5) neurons in stereo perception in the awake macaque by Krug, K, Cumming, BG, Parker, A

Defining the V5/MT neuronal pool for perceptual decisions in a visual stereo-motion task by Krug, K, Curnow, T, Parker, A

Defining the V5/MT neuronal pool for perceptual decisions in a visual stereo-motion task by Krug, K, Curnow, TL, Parker, AJ

“…We defined the perceptual pool in extrastriate visual area V5/MT for a stereo-motion task, based on trial-by-trial co-variation between perceptual decisions and neuronal firing (choice probability (CP)). …”

Comparing perceptual signals of single V5/MT neurons in two binocular depth tasks. by Krug, K, Cumming, BG, Parker, A

“…We compared the responses of those single neurons that show CPs in one stereoscopic depth task with their responses in another stereo task. Each neuron was tested for the presence of 1) CPs during a task in which macaques responded to the sign of binocular depth in a structure-from-motion stimulus, to judge its direction of three-dimensional rotation and 2) a consistent response to the stereo disparity of binocularly anti-correlated stimuli. …”

A common neuronal code for perceptual processes in visual cortex? Comparing choice and attentional correlates in V5/MT. by Krug, K

“…Examples are attentional signals, choice signals for ambiguous images, correlates for binocular rivalry, stereo and shape perception, and so on. These diverse paradigms are aimed at elucidating the neuronal code for perceptual processes, but it has been little studied how they directly compare or even interact. …”

Perceptual switch rates with ambiguous structure-from-motion figures in bipolar disorder. by Krug, K, Brunskill, E, Scarna, A, Goodwin, G, Parker, A

“…We also found that low-level visual capacities, such as stereo threshold, influence perceptual switch rates. …”
