Impaired semantic control in the logopenic variant of primary progressive aphasia

December 21, 2024

Authors: Shalom K Henderson, Siddharth Ramanan, Matthew A Rouse, Thomas E Cope, Ajay D Halai, Karalyn E Patterson, James B Rowe, Matthew A Lambon Ralph. Q&A with Shalom Henderson What is this paper about? Even though the absence of object knowledge loss/semantic representation deficits constitutes ancillary diagnostic criteria for the logopenic variant of primary progressive […]
From the Annual Review of Linguistics, Charting the Course of Aphasia

October 31, 2024

Authors: Manuel Jose Marte, Marissa Russell-Meill, Nicole Carvalho, and Swathi Kiran Figure 1. Brain regions involved in various language tasks. Colors indicate specific tasks associated with each region. The medial frontal gyrus (red) is involved in working memory. The pars triangularis (magenta), pars opercularis (yellow), and pars orbitalis (tan) are involved in speech, language production, […]

Semantic processing in bilingual people with aphasia: An eye-tracking study examining cross-language semantic facilitation and interference.

September 11, 2024

About the Author: Sophie Blankenheim conducted her master’s thesis on this work under the supervision of Maria Varkanitsa Summary Bilingual lexical processing involves simultaneous activation of both languages, with encountering a word in one language priming the equivalent word in the other. Previous research on healthy individuals has shown that naming responses are slowed down […]
What we mean when we say semantic: Toward a multidisciplinary semantic glossary

September 4, 2024

Reilly, J., Shain, C., Borghesani, V., Kuhnke, P., Vigliocco, G., Peelle, J. E., Mahon, B. Z., Buxbaum, L. J., Majid, A., Brysbaert, M., Borghi, A. M., De Deyne, S., Dove, G., Papeo, L., Pexman, P. M., Poeppel, D., Lupyan, G., Boggio, P., Hickok, G., . . . Vinson, D. (2024). What we mean when we […]
A Lesion-aware Edge-based Graph Neural Network for Predicting Language Ability in Patients with Post-stroke Aphasia

September 3, 2024

Evolution of word production errors after typicality-based semantic naming treatment in individuals with aphasia

August 2, 2024

Authors: Ran Li, Natalie Gilmore, Mia O’Connell, Swathi Kiran Q&A with Ran Li What is this paper about and why are the results important? This study implemented an error coding scale to assess changes in word production errors following a semantic-based naming therapy in individuals with chronic aphasia. It provides insights into the linguistic mechanisms that […]
Pars opercularis underlies efferent predictions and successful auditory feedback processing in speech: Evidence from left-hemisphere stroke

May 24, 2024

Interview with collaborators of the Center for Brain Recovery and publication authors Sarah Beach (MIT) and Caroline Niziolek (University of Wisconsin Madison) Abstract Hearing one’s own speech allows for acoustic self-monitoring in real time. Left-hemisphere motor planning regions are thought to give rise to efferent predictions that can be compared to true feedback in sensory cortices, resulting […]
Quantifying Dosage in Self-Managed Speech-Language Therapy: Exploring Components of Cumulative Intervention Intensity in a Real-World Mobile Health Data Set

April 26, 2024

Q&A with Claire Cordella What is the purpose of your research? Cumulative Intervention Intensity (CII; Baker 2012) is a proposed framework for conceptualizing and calculating dose which has been used to quantify intensity of speech-language therapy (SLT) in highly controlled laboratory studies and clinical trials. However, it is unknown whether CII can be applied to characterize […]
