What does a person with akinetopsia see?

Patients with akinetopsia say that smooth movements of objects appear as a discontinuous freeze frame image [2]. Therefore, patients have difficulty, for example, in pouring tea into a cup because the fluid appears to be frozen, like a glacier [3].

How does akinetopsia affect daily life?

Gross akinetopsia Patients have profound motion blindness and struggle in performing the activities of daily living. Instead of seeing vision as a cinema reel, these patients have trouble perceiving gross motion.

What do people with motion blindness see?

Characteristics. People who suffer from motion blindness have normal vision: They can see different objects sharply, can tell the distance between them (that one is farther away than the other) and they see the different colors the objects might have. This applies to shapes, objects and faces.

What is the visual agnosia?

General Discussion. Primary visual agnosia is a rare neurological disorder characterized by the total or partial loss of the ability to recognize and identify familiar objects and/or people by sight. This occurs without loss of the ability to actually see the object or person.

What part of the brain does Akinetopsia effect?

Akinetopsia is thought to be associated with damage to the V5 medial temporal (MT) portion of the brain, involving the tempro-parieto-occipital junction. It is mostly secondary to bilateral disease however has been described in unilateral lesions.

Can people with Akinetopsia drive?

Akinetopsia resulted in illusory kinetopsia on driving and the traffic accident.

Can akinetopsia be cured?

Due to the rare nature of this condition, there is currently no effective treatment or cure for akinetopsia.

What type of vision detects motion?

To determine the direction and motion of objects, the brain relies on binocular vision. Small differences in images from each eye are delivered to the brain simultaneously, and the slight differences between these two images are used to assess the direction of an object’s movement.

Can people with akinetopsia drive?

How do people with prosopagnosia identify others?

Some people with prosopagnosia cannot recognise certain facial expressions, judge a person’s age or gender, or follow a person’s gaze. Others may not even recognise their own face in the mirror or in photos. Prosopagnosia can affect a person’s ability to recognise objects, such as places or cars.

What is akinetopsia in Aspergers?

Akinetopsia is an acquired defect of visual motion perception. Generally, patients do not lack all ability to see any motion, but are impaired in more complex motion judgments, such as perception of the speed of one object relative to another, or determining overall direction of motion in noisy displays.

What is an example of akinetopsia?

This is a perfect example of akinetopsia. Akinetopsia is the inability to perceive objects in motion. It’s a kind of visual agnosia. People who suffer from it see the world in still frames. As a result, they have a lot of trouble doing simple things such as crossing the street.

What is cerebral akinetopsia and motion blindness?

The extensive study of this patient, referred to as LM, has informed our understanding of cerebral akinetopsia and motion processing in humans in general (Zihl and Heywood, 2015 ). Cerebral akinetopsia is also referred to colloquially as motion blindness.

What is the difference between motion sensitivity and kinetopsia?

In monkeys, motion sensitivity is the dominant property of areas V5 (MST area) and adjacent V5A (MST area), but is also found elsewhere, as in area V3A. Akinetopsia is produced by bilateral lesions of the lateral occipitotemporal cortex, where the human homolog of V5/V5A is located, and is very rare.
