Vergence–accommodation conflicts hinder visual performance and cause visual fatigue

Visual Perceptual Conflicts and Illusions

Vision is arguably the most important of the human senses for a Warfighter. The purpose of visual processing is to take in information about the world around us and make sense of it (Smith and Kosslyn, 2007); vision involves the sensing and the interpretation of light. The visual sense organs are the eyes, which convert incoming light energy into electrical signals (see Chapter 6, Basic Anatomy...

E-Readers and Visual Fatigue

The mass digitization of books is changing the way information is created, disseminated and displayed. Electronic book readers (e-readers) generally refer to two main display technologies: the electronic ink (E-ink) and the liquid crystal display (LCD). Both technologies have advantages and disadvantages, but the question whether one or the other triggers less visual fatigue is still open. The ...

Visual cortex: Fatigue and adaptation

Prolonged exposure to a visual pattern perturbs visual perception, affecting the appearance of subsequently viewed patterns. Recent results demonstrate that this visual adaptation is explained partly by a cellular mechanism acting in individual cortical neurons.

Understanding visual fatigue.

Effects of visual deprivation on synaptic plasticity of visual cortex

  TBS (Theta Burst Stimulation) and PBs (Primed Bursts) are among effective tetanic stimulations for induction of LTP in hippocampus. Recent studies have indicated that TBS is effective in LTP induction in layer III synapses of neocortex, only if applied to layer IV. However, the possibility of neocortical LTP induction using PBs, has not yet been investigated. Sensory deprivation greatly influ...
