CATEGORY-SPECIFIC NAMING DEFICIT AFTER<br /> EPILEPSY SURGERY IN THE LEFT TEMPORAL<br /> LOBE: FACT OR FICTION?
Journal Title: Acta Neuropsychologica - Year 2007, Vol 5, Issue 1
Abstract
Objective. Object naming for specific semantic categories was assessedin a sample of 24 patients with left temporal lobe epilepsy. Testing occurredduring preoperative clinical diagnostics and 6 months after surgery.Background. Category-specific deficits constitute a naming disorder forliving or nonliving objects or subsets of these categories (e.g. animals, fruits,tools) with relatively spared naming for other object domains. Theoretically,these deficits can provide insight into the storage of conceptual informationin distinct brain regions.Method. For the purpose of this study a test battery of 160 clipart illustrationswas used. Object naming was registered for different sets of living andnonliving categories.Results. Two patients with preoperative intact naming performance showeda specific naming deficit for living categories (food, animals) after surgery in theleft temporal lobe.Conclusions. Category-specific naming deficits comprise a potential negativeside effect after surgery in the speech-dominant left temporal lobe.Based on the requirements for object identification it is hypothesized that theleft temporal lobe represents a visual feature store sensitive for the identification of living objects.
