Spatial and color hallucinations in a mathematical model of primary visual cortex

  title={Spatial and color hallucinations in a mathematical model of primary visual cortex},
  author={Olivier D. Faugeras and Anna Song and Romain Veltz},
We study a simplified model of the representation of colors in the primate primary cortical visual area V1. The model is described by an initial value problem related to a Hammerstein equation. The solutions to this problem represent the variation of the activity of populations of neurons in V1 as a function of space and color. The two space variables describe the spatial extent of the cortex while the two color variables describe the hue and the saturation represented at every location in the… 


Geometric visual hallucinations, Euclidean symmetry and the functional architecture of striate cortex.
This paper studies the various planforms that emerge when the model V1 dynamics become unstable under the presumed action of hallucinogens or flickering lights, and shows that the planforms correspond to the axial subgroups of E(2), under the shift-twist action.
A neural field model for color perception unifying assimilation and contrast
A neural field model of color perception with spatial context for the visual area V1 of the cortex is proposed, which reconciles two opposing perceptual phenomena, known as simultaneous contrast and chromatic assimilation.

It is shown that if this global structure is reiterated at the local level, then the sequence regularity of the simple cells of area 17 may be accounted for as well and the observed curve of cortical magnification, the linear scaling of receptive field size with eccentricity, and the mapping of global visual field landmarks.
Oculocentric spatial representation in parietal cortex.
The results indicate that LIP can analyze visual space without ever forming a representation of absolute target position.
Chromatic micromaps in primary visual cortex
Two-photon calcium imaging in macaques is used to examine the fine structure of chromatic representation and finds that neurons responsive to spatially uniform, chromatic stimuli form unambiguous clusters that coincide with blobs.
Whither the hypercolumn?
The results support an underlying common mechanism that constrains the anatomical extent of hypercolumn systems, and highlight the original definition of the cortical hypercolumn.
Mnemonic coding of visual space in the monkey's dorsolateral prefrontal cortex.
An oculomotor delayed-response task was used to examine the spatial memory functions of neurons in primate prefrontal cortex and found that inhibitory responses were usually strongest for, or centered about, cue directions roughly opposite those optimal for excitatory responses.
Nonlinear analysis methods in neural field models
This thesis deals with mesoscopic models of cortex called neural fields. The neural field equations describe the activity of neuronal populations, with common anatomical / functional properties. They
Blobs and color vision
The structure of the monkey striate cortex, including its inputs and outputs, and the physiological basis of color vision are studied.
A mathematical theory of the functional dynamics of cortical and thalamic nervous tissue
It is shown that this particular mode reproduces some of the phenomenology of visual psychophysics, including spatial modulation transfer function determinations, certain metacontrast effects, and the spatial hysteresis phenomenon found in stereopsis.
