Agrammatism: Behavioral Description and Neurobiological Explanation

  title={Agrammatism: Behavioral Description and Neurobiological Explanation},
  author={Friedemann Pulvermller},
  journal={Journal of Cognitive Neuroscience},
Subjects with brain damage resulting in agrammatic aphasia frequently omit or substitute function items (function words and inflectional affixes). However, they show only mild deficits in using meaningful content words. Agrammatics' performance on comprehension tests reveals a rather complex pattern. They usually understand active sentences correctly, but perform on chance level on passives.
