Introduction: Classical neuropsychological and cognitive models suggest distinct neural networks for verbs and nouns.
Aim of the study: Two verbal fluency tasks were used in our study to test the hypothesis of different neural mechanisms of verb and noun fluency. Brain activation (functional magnetic resonance – fMRI) was analyzed during task performances of both categories. Brain activation was measured with fMRI during a block schema of tasks in 35 healthy individuals.
Results: There were differences in localization and level of brain activation. Verbs involved more activation in the temporo-occipital areas in both hemispheres than nouns.
Conclusions: The results are consistent with current data. Verbs are more based on perceptual-semantic processes than nouns.
