Visual Attention and Motion

Visual attention and movement Human observers are very effective in detecting movement. If you can detect the target while still, it will be even more when it is moving. The brain uses several clues to help perceive movement, including information from all five senses. The focus of this article is on the vision system and how it perceives motion visually. Movement is partially perceived by the pattern of light changes on the retina. However, since it is possible to create a change in the pattern of these lights by perceiving the movement while keeping the image stable on the retina, or by moving the head and eyes, this explains the perception of complete motion There is none.

Changes in the structure (usually lesions) of the brain disrupt the sensory information, in this case the psychological process of understanding visual information. Due to the anatomical separation of visual motion processing from other functions, only visual motion disturbance is possible. As with akinesia, color perception may be selectively disturbed like full color blindness. Despite normal spatial vision, flicker detection, stereo and color perception, movement is still not visible. Other complete functions include visual space recognition and shape, visual recognition of objects and faces. In addition to simple perception, movement disorders can also interfere with visual exercise tasks such as reaching objects and capturing objects. Feedback on your action seems important when completing the task

Ataxia is a very rare illness that allows you to see still objects but loses the ability to perceive movement within the field of view. Akinesia is due to certain lesions of the visual cortex. This term was introduced by neurobiologist Semir Zeki in 1991.

Ataxia is a rare sensory disorder that a patient can not perceive movement within the field of view. The patient can see the stationary object without problems, but the movement of the world does not exist. Most of the findings on Akinetopsia were learned from a famous case study named Patient LM. Because this disease is rare, no effective treatment or cure has been found (Osview, 2013). Ataxia is a neuropsychological disorder caused by lesions in the V 5 region of the brain structure and may impair the processing of visual sensory information. However, with this rare illness, only exercise is impaired. Patients usually can identify the same object as the lesion by looking at the color. Visual motion is anatomically separate from these visual functions (Vaina, 1995)

Opisia stationary objects for Akinetopsis (also known as ataxia or motor blindness) (Greek: kine for "no", kineshio for "mobile", and "blind" can be seen without problems. There are various degrees of dyskinesia from seeing movement like a reel of a movie to being unable to distinguish any movement There is currently no effective treatment or cure for dyskinesia.In dark movement disorder, It is often explained by treating exercise as a movie reel or multiple exposure photograph.This is the most common dyskinesia and many patients think strobe vision is troublesome movement disorders are often visual slings (Parinopusia), an afterimage remains in every frame of exercise.It is prescription medicine, L It is caused by SD Persistent Perception Disorder (HPPD) and sustained aura without infarction
