Tactile apraxia: unimodal apractic disorder of tactile object exploration associated with parietal lobe lesions.
Tactile apraxia is characterized by an isolated disturbance of hand movements for use of and interaction with an object (transitive movements) in the presence of preserved intransitive movements (movements without use of an object, for example repetitive movements or gestures). It is, however, still unclear whether motor and sensory abnormalities represent causal or associated features of tacti...
متن کاملTactile perceptual rivalry and tactile-amorphosynthesis in the localization of cerebral lesions; with special reference to parietal lobes.
Introduction Recently attention of neurologists has been directed to the clinical value of using bilateral simultaneous and ipsilateral double stimuli in testing cutaneous sensations. If two similar stimuli are applied simultaneously on the two sides of the body, eyes being closed, the patient announces that he feels the object only on the unaffected side. When each side is tested separately, t...
متن کاملOsseoperception: active tactile sensibility of osseointegrated dental implants.
PURPOSE The phenomenon of developing a certain tactile sensibility through osseointegrated dental implants is called osseoperception. Active tactile sensibility can be tested by having the subject bite on test bodies. The aim of the study was to describe the active tactile sensibility of single-tooth implants based on the 50% value and the slope of the sensibility curve at the 50% value. MATE...
متن کاملMultiple parietal operculum subdivisions in humans: tactile activation maps.
We focused the present analysis on blood-oxygen-level-dependent responses evoked in four architectonic subdivisions of human posterior parietal operculum (PO) during two groups of tasks involving either vibrotactile stimulation or rubbing different surfaces against the right index finger pad. Activity localized in previously defined parietal opercular subdivisions, OP 1-4, was co-registered to ...
متن کاملSummation of rapid tactile stimuli in parietal lobe disease.
The perception threshold for trains of rapid tactile pulses, applied to the index finger, has been measured in patients with parietal lobe lesions and in patients with median nerve lesions. The former patients had increased perception thresholds for single tactile pulses on the abnormal side. With successively prolonged pulse trains, the threshold decreased exponentially to reach a stable level...
