The Toiber test - a test for lateralization of tactile stimuli, is named after the American neuropsychologist , who first used this diagnostic method.
Content
Methodology
In this test, the subject is first touched with one hand, then with the other and both. After each touch, the subject answers which hands are touched. This test can be complicated by setting the subject to assess the number of stimuli, that is, to touch the hand in several places.
Localization of Violation
With lesions of the right hemisphere, the Toiber test can reveal left-handed tactile disregard. In this case, the patient does not feel touch on the left hand during stimulation of both hands. The problem with the correct identification of the hand indicates violations of the parietal zone of the brain, as well as the median structures and the medio-basal parts of the frontal lobes. Violation of these departments is possible with late degenerative dementia (for example, Alzheimer's disease ). If the subject finds it difficult to determine the number of stimuli, this indicates lesions of the parietal cortex or the underlying subcortical structures.
