Journal ArticleDOI
A multivariate lesion symptom mapping toolbox and examination of lesion-volume biases and correction methods in lesion-symptom mapping.
TL;DR: A new toolbox for support vector regression lesion‐symptom mapping (SVR‐LSM) is provided that provides a graphical interface and enhances the flexibility and rigor of analyses that can be conducted using this method.
Journal ArticleDOI
What role does the anterior temporal lobe play in sentence-level processing? neural correlates of syntactic processing in semantic variant primary progressive aphasia
Stephen M. Wilson,Andrew T. DeMarco,Maya L. Henry,Benno Gesierich,Miranda Babiak,Maria Luisa Mandelli,Bruce L. Miller,Maria Luisa Gorno-Tempini +7 more
TL;DR: The findings indicate that spared syntactic processing in semantic PPA depends on preserved functionality of structurally intact left frontal regions and moderately atrophic left posterior temporal regions, but no functional reorganization was apparent as a consequence of anterior temporal atrophy and dysfunction.
Journal ArticleDOI
Examining the value of lexical retrieval treatment in primary progressive aphasia: two positive cases.
Maya L. Henry,Kindle Rising,Andrew T. DeMarco,Bruce L. Miller,Maria Luisa Gorno-Tempini,Pélagie M. Beeson +5 more
TL;DR: Two cases are presented, one with semantic variant of PPA and the other with logopenic PPA, each of whom underwent treatment that was unique in its focus on training self-cueing strategies to engage residual language skills, and showed maintenance of gains as well as generalization to untrained lexical items.
Journal ArticleDOI
Variable disruption of a syntactic processing network in primary progressive aphasia
Stephen M. Wilson,Stephen M. Wilson,Andrew T. DeMarco,Maya L. Henry,Maya L. Henry,Benno Gesierich,Miranda Babiak,Bruce L. Miller,Maria Luisa Gorno-Tempini +8 more
TL;DR: It is found that the individual degree of syntactic comprehension impairment was predicted by left frontal atrophy, but also by functional disruption of a broader syntactic processing network, comprising left posterior frontal cortex, left posterior temporal cortex, and the left intraparietal sulcus and adjacent regions.
Journal ArticleDOI
Localization of Phonological and Semantic Contributions to Reading
J. Vivian Dickens,Mackenzie E. Fama,Mackenzie E. Fama,Andrew T. DeMarco,Elizabeth H. Lacey,Elizabeth H. Lacey,Rhonda B. Friedman,Peter E. Turkeltaub,Peter E. Turkeltaub +8 more
TL;DR: Support vector regression lesion–symptom mapping of stroke survivors not preselected for stereotyped dissociations revealed that effects of lexicality, orthographic regularity, and concreteness on reading differentially depend on areas subserving auditory–motor integration and semantic control.
