Eligibility Criteria
INCLUSION CRITERIA: We will include patients with thromboembolic non-hemorrhagic hemispheric lesions and with hemorrhagic hemispheric lesions (as documented by CT or MRI) at least 12 months after the stroke. We will choose subjects with chronic stable aphasia, that initially presented with severe aphasia and have partially recovered. Assessment of the initial functional state will be taken either from patient report or medical records. All of the aphasic patients are already known to the investigators from the NIDCD. EXCLUSION CRITERIA - HEALTHY CONTROLS: Unable to perform the task (naming of everyday objects in less than 10 s). History of alcohol or drug abuse or psychiatric illness like depression. Epilepsy.
