Motion Sensitivity in Central and Peripheral Vision

American journal of optometry and physiological optic, 1986
ABSTRACT The visual resolution of motion is important both for indicating the presence of moving objects and for assisting locomotion and spatial orientation. Additionally, motion may enhance the visibility of low contrast features of the environment.

Orientation Sensitivity in the Peripheral Visual Field

Perception, 1984
Orientation sensitivity in the peripheral visual field has been tested in two tasks: (a) setting horizontal the orientation of a grating at various retinal eccentricities, and (b) matching the orientation of a peripherally viewed grating as close as possible to an oblique reference viewed foveally.

Measurements of contrast sensitivity for peripheral vision

ACM Symposium on Applied Perception 2019, 2019
Contrast detection thresholds were measured for the eccentricities from 0° to 27° and a range of stimuli frequencies from 0.125cpd to 16cpd. The measurements were motivated by the need to collect visual performance data for the gaze-contingent rendering system.

Photopic spectral sensitivity of the peripheral retina*†

Journal of the Optical Society of America, 1975
Photopic spectral sensitivity was determined in the mid- and far-peripheral retina by two methods. The first consisted of measuring increment thresholds on a background similar in spectral composition to CIE Source A. The resulting spectral-sensitivity functions displayed maxima at about 440 nm, in agreement with previous work.

Peripheral and central mechanisms of visceral sensitization in man [PDF]

Neurogastroenterology and Motility, 2007
Visceral hypersensitivity (perception of gastrointestinal sensory events at a lower-than-normal threshold) is considered to be an important pathophysiological mechanism in the development of functional gastrointestinal disorders (FGIDs), such as ...

Antagonizing peripheral sensitization in migraine

2004
Abstract Migraine is an episodic brain disorder characterized by attacks of throbbing head pain and sensitization of the cutaneous facial skin. Current research indicates that the dural blood vessels and their neural connectivity with the trigeminocervical complex play a fundamental role in the generation of these symptoms.

Peripheral serotonergic receptor sensitivity in depressive illness

Journal of Affective Disorders, 1984
Platelet aggregation induced by 5-HT was used as a measure of the functional responsiveness of peripheral 5-HT receptors in controls and drug-free depressed patients. No significantly different aggregatory response (5-HT/ADP ratio) was noted between the controls and drug-free depressed patients.

Local sensitivities and the representation of peripherality

Journal of Transport Geography, 1996
Abstract This paper focuses on the ill-defined but commonly used concept of peripherality. Using a blend of previous research, and the representations made by local agencies during the 1992–1993 Assisted Areas map review, it explores the sensitivity to peripherality on the part of the local area and examines ways in which perceived peripherality — as

Sensitized peripheral nociception in experimental diabetes of the rat

Pain, 2010
Painful neuropathy is a common complication of diabetes. Particularly in the early stage of diabetic neuropathy, patients are characterized by burning feet, hyperalgesia to heat, and mechanical stimuli, as if residual nociceptors were sensitized. Such symptoms are barely explained by common pathophysiological concepts of diabetic neuropathy.

The Peripheral Mechanisms of Sensitization of Inflamed Tissues

1976
Publisher Summary This chapter presents the peripheral mechanisms of sensitization of inflamed tissues. Responses of the cutaneous mechanoreceptors to tactile stimulation of the inflamed area of the skin are studied in acute experiments on cats and dogs, using the collision technique.
