Research in the Language Neuroscience Laboratory focuses on understanding the neural basis of language. We combine structural and functional neuroimaging techniques with linguistic analysis to study language processing, and how it breaks down in patients with different kinds of aphasia. We work with patients with aphasias of various etiologies, including stroke and neurodegenerative disease. Language domains of particular interest are syntactic processing and lexical access.

Auditory-perceptual rating of connected speech in aphasia
We describe a system for assessing connected speech in aphasia, based on the auditory-perceptual approach that is used in the assessment and diagnosis of motor speech disorders. We show that APROCSA is reliable and valid, and in our sample, explains 79% of the variance in connected speech profiles in terms of four latent factors: Paraphasia, Logopenia, Agrammatism, and Motor Speech.

Lunch with Jane Wilkerson Yount
We had a great lunch with Jane Wilkerson Yount (seated), who generously endowed the Wilkerson Yount Research Fund in 2017. This fund supports research in adult neurogenic communication disorders at the Vanderbilt Bill Wilkerson Center, and will be supporting a new investigation into treated recovery from post-stroke aphasia. Standing: Stephen Wilson, Melissa Duff, and Anne Marie Tharpe.

Neurobiology of Language
The new open access journal Neurobiology of Language launches tomorrow, supported by the Society for the Neurobiology of Language and MIT Press. I'm proud to serve as an inaugural member of the editorial board. Thanks to the editors-in-chief Steve Small and Kate Watkins, and everyone who made this possible.
I will present some of our recent work as part of the 2018 ASHA Research Symposium "Advances in Neuroplasticity Research: Language Recovery in Aphasia".

An adaptive semantic matching paradigm for reliable and valid language mapping in individuals with aphasia
We describe an adaptive semantic matching paradigm and demonstrate that it is a feasible, reliable and valid method for mapping language regions in people with aphasia.

Neural representation of vowel formants in tonotopic auditory cortex
Cortical encoding of vowels is scaffolded on tonotopy, a fundamental organizing principle of auditory cortex that is not language-specific.

Selective interference with syntactic encoding during sentence production by direct electrocortical stimulation of the inferior frontal gyrus
Direct cortical stimulation of the left inferior frontal gyrus can interfere with syntactic encoding but not single word processing, suggesting that this region plays an important role in the encoding of syntactic structure during sentence production.

A quick aphasia battery for efficient, reliable, and multidimensional assessment of language function
The Quick Aphasia Battery (QAB) aims to provide a reliable and multidimensional assessment of language function in about a quarter of an hour, bridging the gap between comprehensive batteries and rapid screening instruments.
