Linking Visual Cortex to Visual Perception: An Alternative to the Gestalt Bubble [PDF]

open access: yes, 2003
Lehar's lively discussion builds on a critique of neural models of vision that is incorrect in its general and specific claims. He espouses a Gestalt perceptual approach, rather than one consistent with the "objective neurophysiological state of the ...

Functional correlates of optic flow motion processing in Parkinson’s disease [PDF]

open access: yes, 2014
The visual input created by the relative motion between an individual and the environment, also called optic flow, influences the sense of self-motion, postural orientation, veering of gait, and visuospatial cognition.

Choice of analysis pathway dramatically affects statistical outcomes in breaking continuous flash suppression

open access: yesScientific Reports, 2017
Breaking Continuous Flash Suppression (bCFS) has been adopted as an appealing means to study human visual awareness, but the literature is beclouded by inconsistent and contradictory results.

Optimal measurement of visual motion across spatial and temporal scales [PDF]

open access: yes, 2014
Sensory systems use limited resources to mediate the perception of a great variety of objects and events. Here a normative framework is presented for exploring how the problem of efficient allocation of resources can be solved in visual perception ...

Linking the Laminar Circuits of Visual Cortex to Visual Perception [PDF]

open access: yes, 2001
A detailed neural model is being developed of how the laminar circuits of visual cortical areas V1 and V2 implement context-sensitive binding processes such as perceptual grouping and attention, and develop and learn in a stable way.

Visual distortion of body size modulates pain perception [PDF]

open access: yes, 2011
Pain is a complex subjective experience, that can be shaped by several cognitive, psychological and even contextual variables. For example, simply viewing the body reduces the reported intensity of acute physical pain.

Perception Of Visual Speed While Moving [PDF]

open access: yes, 2005
During self-motion, the world normally appears stationary. In part, this may be due to reductions in visual motion signals during self-motion. In 8 experiments, the authors used magnitude estimation to characterize changes in visual speed perception as a
