The trace deletion hypothesis and the tree-pruning hypothesis: Still validcharacterizations of Broca's aphasia

I begin with a characterization of neurolinguistic theories, trying to pinp oint some general properties that an account of brain/language relation sho uld have. I then address specific criticisms made in the commentaries regar ding the syntactic theory assumed in the target article, properties of the Trace Deletion Hypothesis (TDH) and the Tree-Pruning Hypothesis (TPH), othe r experimental results from aphasia, and findings from functional neuroimag ing. despite the criticism, the picture of the limited role of Broca's ara remains unchanged.
