What is stereognosis?
stereognosis is a medical term for the ability to identify objects over the touch. When a person processes the material, he sends the touch signals and the brain identifies the object. This ability is present in healthy people, but can be affected in people who have lesions in the brain.
Arcane Scientific Term for Touch Identification, stereognosis, stems from Greek words. For example, stereos means solid in Greek. gnosis is another Greek word and means knowledge. So the whole word means that it is known to the person. If a person cannot properly identify solids, then they suffer from astereognosis, or lack of a solid knowledge. A view is an important meaning and usually people use their view in trying to identify the object. The fragrance can be in some way useful in identifying fragrant objects such as strawberries or perfumes, and hearing only actuals applies to objects that give recognizable noise. Object tastings are useful in distinguishedThe food ingredients are not suitable for many other objects.
Touch is the feeling that everyone uses all day, every day, most of the time without noticing it. Identifying the touch comes to the forefront when stone is present in the shoe, deformation is covered with crumbs, or when, in the dark cinema theater, the film player wants to hunt a rubber candy from the box. Stereognosis is this ability to detect objects when other senses are not involved.
Healthy people usually have no difficulty in identifying most of the subjects that their hands encounter. This is because the touch receptors in their hands receive information about the texture, temperature, shape and size of the object and send information to the brain to interpret properly. The brain uses information signs and previous experience with similar objects to find out what the object is.
When the brain is damaged, the signals can be misinterpreted from hands. PersonsAnd the affected lesions in the brain involved, such as the sensory bark of parietal lobe, cannot properly recognize the object in hand. For this reason, a stereogosis test is sometimes performed in patients who may have suffered a brain lesion in this area.
neurological tests of this kind simply test the patient's ability to identify most of the common objects placed in his hand. Pens, paper clips or coins are common enough for this test. A patient who is unable to identify common objects suffers from astereognosis, showing that a brain lesion is present.
