Occlusion (dentistry), the manner in which the upper and lower teeth come together when the mouth is closed; Occlusion miliaria, a skin condition; Occlusive dressing, an air- and water-tight trauma dressing used in first aid; Vascular occlusion, blockage of a blood vessel
Stereopsis is merely relative because a greater or lesser disparity for nearby objects could either mean that those objects differ more or less substantially in relative depth or that the foveated object is nearer or further away (the further away a scene is, the smaller is the retinal disparity indicating the same depth difference).
Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
The penumbral area can also be detected based upon an integration of three factors. These factors include: the site of vessel occlusion, the extent of oligaemia (hypoperfused area surrounding the penumbra, but not at risk of infarction [1]) at that moment, and the mismatch between this perfusion defect and the area of the brain already ...
Individuals have been found to integrate the various stimuli, for example stereoscopic cues and motion occlusion, in different ways. [ 18 ] How the brain combines the different cues – including stereo, motion, vergence angle and monocular cues – for sensing motion in depth and 3D object position is an area of active research in vision ...
Physiological psychology is a subdivision of behavioral neuroscience (biological psychology) that studies the neural mechanisms of perception and behavior through direct manipulation of the brains of nonhuman animal subjects in controlled experiments.
Global aphasia typically results from an occlusion to the trunk of the middle cerebral artery (MCA), [2] which affects a large portion of the perisylvian region of the left cortex. [7] Global aphasia is usually a result of a thrombotic stroke, which occurs when a blood clot forms in the brain's blood vessels.
Vascular occlusion is a blockage of a blood vessel, usually with a clot. It differs from thrombosis in that it can be used to describe any form of blockage, not just one formed by a clot. When it occurs in a major vein , it can, in some cases, cause deep vein thrombosis .
