Neuroimaging And Recovery Of Language In Aphasia, Cynthia K. Thompson, Dirk B. Den Ouden Nov 2008

Neuroimaging And Recovery Of Language In Aphasia, Cynthia K. Thompson, Dirk B. Den Ouden

Communication Sciences and Disorders Faculty Articles and Research

The use of functional neuroimaging techniques has advanced what is known about the neural mechanisms used to support language processing in aphasia resulting from brain damage. This paper highlights recent findings derived from neuroimaging studies focused on neuroplasticity of language networks, the role of the left and right hemispheres in this process, and studies examining how treatment affects the neurobiology of recovery. We point out variability across studies as well as factors related to this variability, and we emphasize challenges that remain for research.

Argument Structure Effects In Action Verb Naming In Static And Dynamic Conditions, Dirk B. Den Ouden, Steve Fix, Todd B. Parrish, Cynthia K. Thompson

Argument structure, as in the participant roles entailed within the lexical representation of verbs, affects verb processing. Recent neuroimaging studies show that when verbs are heard or read, the posterior temporoparietal region shows increased activation for verbs with greater versus lesser argument structure complexity, usually bilaterally. In addition, patients with agrammatic aphasia show verb production deficits, graded based on argument structure complexity. In the present study, we used fMRI to examine the neural correlates of verb production in overt action naming conditions. In addition, we tested the differential effects of naming when verbs were presented dynamically in video segments versus …
