Many observers see geometric visual hallucinations after taking hallucinogens such as LSD, cannabis, mescaline or psilocybin; on viewing bright flickering lights; on waking up or falling asleep; in near-death experiences; and in many other syndromes. Klver organized the images into four groups called form constants: (I) tunnels and funnels, (II) spirals, (III) lattices, including honeycombs and triangles, and (IV) cobwebs. In most cases, the images are seen in both eyes and move with them. We… Expand
The Strasbourg Visual Scale: A Novel Method to Assess Visual Hallucinations
TLDR
The “Strasbourg Visual Scale” is developed, a novel computerized tool that allows us to explore and capture the subjective experience of visual hallucinations by circumventing the difficulties associated with verbal descriptions, and to which extent it could complement existing scales. Expand
Bifurcation on the Visual Cortex with Weakly Anisotropic Lateral Coupling
TLDR
Bressloff, Cowan, Golubitsky, Thomas, and Wiener generalize this class of models to include the orientation tuning of neurons in V1 and the Hubel and Wiesel hypercolumns. Expand
A functional magnetic resonance imaging investigation of visual hallucinations in the human striate cortex
TLDR
It is concluded that small circular objects, in rotation, tend to leave greater hallucinating impressions in the visual region, and the similarity between observed activation patterns and those reported in conditions such as epilepsy and visual hallucinations can help elucidate the cortical mechanisms underlying these conditions. Expand
A Bidirectional Link between Brain Oscillations and Geometric Patterns
TLDR
It is demonstrated that the same flicker frequencies that preferentially induced radial (<10 Hz) or spiral hallucinations in a behavioral experiment involving full-field uniform flicker also showed selective oscillatory EEG enhancement when observers viewed a genuine static image of a radial or spiral pattern without any flicker. Expand
Elementary visual hallucinations and their relationships to neural pattern-forming mechanisms.
TLDR
The Klüver cortical activity patterns are examples of self-organized pattern formation that arise from nonlinear dynamic interactions between excitatory and inhibitory cortical neurons; with reasonable modifications, this model accounts for a wide range of hallucinated patterns. Expand
Serotonergic Hallucinogen-Induced Visual Perceptual Alterations.
TLDR
The hallucinogen-induced parallel decrease of the N170 visual evoked potential and increased medial P1 potential will be discussed as key mechanisms for inducing a dysbalance between global integration and early visual gain that may explain several hallucinogens-induced visual experiences, including visual hallucinations, illusions, and intensifications.

A computational perspective on migraine aura
TLDR
An approach to the computational modeling of migraine aura is described, based on the principles of cortical organization and active wave propagation in an excitable medium, and the simulations produced are in agreement with descriptions and drawings of visual aura from migraine patients. Expand
SEEING WITH EYES CLOSED
Our perceptual machinery attunes itself to the structural features of its habitat. It evolves and develops in active interactions with the world over long evolutionary time scales and shortExpand

In this dissertation, I used theories of serotonin to understand the effects of serotonergic hallucinogens on visual perception and attention. I began by studying hallucinatory syndromes in drugExpand

TLDR
It is shown that in presence of a visual input, the stable eigenmodes of the linearized operator represent perceptual units of the visual stimulus, strictly related to dimensionality reduction and clustering problems. Expand

Geometric visual hallucinations, Euclidean symmetry and the functional architecture of striate cortex.
TLDR
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. Expand

Hallucinations
TLDR
In an illusion a sense organ is stimulated in the ordinary way by an object outside the body, and the stimulus is carried to the cerebral centre; but the intellect wrongly interprets the sensation. Expand

Anatomical substrates for early stages in cortical processing of visual information in the macaque monkey
TLDR
A broader knowledge of cortical visual processing suggests that an important factor in determining each area's,distinctive response properties and overall functional relevance is the channelling of particular types of visual information to that area (for example, direction-selective V1 inputs to area V5), together with uniquely structured associations between different types of information within each area.

Receptive fields, binocular interaction and functional architecture in the cat's visual cortex
TLDR
This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.

Neurophysiological data are presented that show the later part of V1 neurons' responses reflecting higher order perceptual computations related to Ullman's (Cognition 1984; 18:97-159) visual routines and Marr's (Vision NJ: Freeman 1982) full primal sketch, 2 1/2D sketch and 3D model. Expand

The aim of the enterprise is to illustrate successful attempts in a theoretical field, such as Geometry, to take advantage of the complexity of brain organization and to open a new explanatory referential. Expand
A mathematical theory of visual hallucination patterns
TLDR
Bifurcation theory and group theory are used to demonstrate the existence of a variety of doublyperiodic patterns, hexagons, rolls, etc., as solutions to the field equations for the net activity. Expand
