    "abstract": "This study investigated the neural bases of event-related\nsemantic-memory deficits among people with aphasia due to\nleft-hemisphere (LH) stroke. A novel task using naturalistic\nphotographic stimuli and patient-friendly procedures was\nused to test event-related semantic knowledge. In the task,\nparticipants decided whether depicted events were normal\n(represented in semantic memory) or were abnormal (not\nrepresented in semantic memory). Performance on this Event\ntask was correlated with deficits in action- and object-concept\nprocessing and on standardized language measures, especially\naction- and verb-processing deficits. Logistic regression\nanalyses examined lesion correlates of patient performance on\nthe Event task. Surprisingly, increasing LH lesion size in\naction ROIs was associated with improved performance on\nthe event-knowledge task. These findings suggest that action\nprocessing may play a special role in event-related semantic\nmemory representations. Furthermore, they are consistent\nwith recent claims that the right hemisphere may be\nespecially important for activation of event-related\nknowledge.",
