In cognitive psychology, visuospatial function refers to cognitive processes necessary to "identify, integrate, and analyze space and visual form, details, structure and spatial relations" in more than one dimension. [1] Visuospatial skills are needed for movement, depth and distance perception, and spatial navigation. [1]
Anything that affects any of these variables can have a negative effect on balance and maintaining posture. [47] This effect has been seen in research involving elderly subjects when compared to young controls, [ 48 ] in glaucoma patients compared to age matched controls, [ 49 ] cataract patients pre and post surgery, [ 50 ] and even something ...
Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke. [citation needed]
Vision has been known to play an important role in balance and postural control in humans, along with proprioception and vestibular function. Monocular vision affects how the brain perceives its surroundings by decreasing the available visual field, impairing peripheral vision on one side of the body, and compromising depth perception, all ...
In addition, the vestibular system's function can be affected by tumours on the vestibulocochlear nerve, an infarct in the brain stem or in cortical regions related to the processing of vestibular signals, and cerebellar atrophy. When the vestibular system and the visual system deliver incongruous results, nausea often occurs.
This is different from visual acuity, which refers to how clearly a person sees (for example "20/20 vision"). A person can have problems with visual perceptual processing even if they have 20/20 vision. The resulting perception is also known as vision, sight, or eyesight (adjectives visual, optical, and ocular, respectively).
Lower brain oxygen levels caused by sleep apnea were linked to changes to the white matter, which could lead to cognitive problem, a new study suggests. Sleep apnea impacts brain in ways that may ...
The balance system works with the visual and skeletal systems (the muscles and joints and their sensors) to maintain orientation or balance. Visual signals sent to the brain about the body's position in relation to its surroundings are processed by the brain and compared to information from the vestibular and skeletal systems.
