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.

Cortical encoding of vowels is scaffolded on tonotopy, a fundamental organizing principle of auditory cortex that is not language-specific.

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.

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.

An amazing birthday gift from my lab members! Probably not the intended use of Vanderbilt’s 3D printer...

An MRI cake for my birthday! Thank you, Deb, Melodie, Sarah and Jillian for the impromptu party...
This paper, based on Stephanie Yagata's Masters thesis, comprises a detailed investigation of early patterns of change in connected speech after focal infarction of Wernicke's area.
The lab has now relocated to the Department of Hearing and Speech Sciences at Vanderbilt University Medical Center.

This paper is based on Alexa's honors thesis, for which she received the award for Excellence in Undergraduate Research from the Department of Speech, Language, and Hearing Sciences for 2015.

Angelica McCarron appeared on KXCI's "The Thesis" today, where she talked about the neural basis of language, explained her three projects, and did some guest DJing. Listen!
Temre Brandt has received the award for Excellence in Undergraduate Research from the Department of Speech, Language, and Hearing Sciences for 2014. This award is in recognition in the critical roles she is played in both our acute stroke project and our inflectional morphology in PPA project.
Julia Fisher has received a GPSC Achievement Award for Outstanding Interdisciplinary Development by a Graduate/Professional Student (Honorable Mention), for her work bridging Lingusitics and Speech, Language, and Hearing Sciences.

Here is a map of core language areas in an individual participant, using our new Siemens Skyra 3T scanner, tiny voxels, hypercapnic normalization, and vein masking. Note the precise localization of language regions to the dorsal bank of the superior temporal sulcus!
It's been a subpar monsoon season for central Tucson, but anyone that got caught out in this today got properly wet!
After a few months of making do with surpus furniture that Scott, Julia and I pieced together, we now have proper furniture in the scanner console room! Lots of fun unplugging 6,000 cords and then trying to remember how to reassemble everything...

I've just uploaded a new version of VLSM: version 2.5 to the Resources page. The new version allows lesion size to be automatically calculated and included as a covariate. To use this feature, simply include 'LesionSize' in your list of variables. This is useful only for analysis of discrete lesions, not for VBM.
The new clinical 3 Tesla Skyra is being installed at the medical center... very exciting!
I've just uploaded a new version of VLSM: version 2.4 to the Resources page. The main development is that an extra text file (roi.txt) with subject-by-subject lesion data for each cluster is now included in the output directory, to facilitate post-hoc analyses such as multiple regression.
It may not look like much, but this is the new research MRI facility at the University of Arizona. The walkway was just poured today! Construction is on track for the new Siemens 3T Skyra scanner to be up and runnning in early 2013...
After Borna's Neurology grand rounds presentation...
Our "Cognitive Neuroscience of Language" class ran an experiment using noise vocoded speech to look at the neural correlates of language intelligibility and effortful speech recognition. Kat "Nico" Carbonell came up with the idea for the study, and Andrew DeMarco prepared the psychtoolbox script. Julia Fisher (pictured below) provided the brain.
Ashley Chavez and Lisa Wilson have been accepted to top masters programs in Speech-Language Pathology. Matt Stib has been accepted to a top medical school. Congratulations to all!
Janette McGuire created this delicious and anatomically accurate depiction of the Wernicke-Lichtheim model.
Our proposal has been funded by the Western Alliance to Expand Student Opportunities (WAESO). Congratulations Ashley.
