A sensitive test for tactile extinction: results in patients with parietal and frontal lobe disease.
A simple test for detecting tactile extinction is described. In a population of parietal-damaged patients it yielded fewer false negatives than the classical clinical procedure. Contrary to expectations, lesions confined to the right frontal lobe produced no extinction, while those in right-handed, left frontal cases revealed ipsilateral extinction with the new test.
