Brain representation of perceptual stimuli at different levels of awareness

no code implementations22 Feb 2022 Birgitta Dresp-Langley

This article questions the widespread assumption that there are brain representations that will always remain unconscious in the sense of being inaccessible to individual awareness under any circumstances.

Consciousness beyond neural fields: expanding the possibilities of what has not yet happened

no code implementations14 Jan 2022 Birgitta Dresp-Langley

In the field theories in physics, any particular region of the presumed space-time continuum and all interactions between elementary objects therein can be objectively measured and/or accounted for mathematically.

The contribution of local variations in hue or contrast to symmetry of things in a thing

no code implementations10 Aug 2021 Birgitta Dresp-Langley

The stimuli are computer generated 2D shape configurations consisting of multiple elements, with and without systematic variations in local color, color saturation, or achromatic contrast producing variations in symmetry of things in a thing.

The quantization error in a Self-Organizing Map as a contrast and colour specific indicator of single-pixel change in large random patterns

no code implementations8 Nov 2020 John M Wandeto, Birgitta Dresp-Langley

The quantization error in a fixed-size Self-Organizing Map (SOM) with unsupervised winner-take-all learning has previously been used successfully to detect, in minimal computation time, highly meaningful changes across images in medical time series and in time series of satellite images.

Children's health in the digital age

no code implementations7 Jul 2020 Birgitta Dresp-Langley

Environmental studies, metabolic research, and state of the art in neurobiology point towards the reduced amount of natural day and sunlight exposure of the developing childs organism, as a consequence of increasingly long hours spent indoors online, as the single unifying source of a whole set of health risks identified worldwide, as is made clear in this review of the current literature.

Unsupervised automatic classification of Scanning Electron Microscopy (SEM) images of CD4+ cells with varying extent of HIV virion infection

no code implementations30 Apr 2019 John M. Wandeto, Birgitta Dresp-Langley

Archiving large sets of medical or cell images in digital libraries may require ordering randomly scattered sets of image data according to specific criteria, such as the spatial extent of a specific local color or contrast content that reveals different meaningful states of a physiological structure, tissue, or cell in a certain order, indicating progression or recession of a pathology, or the progressive response of a cell structure to treatment.
