Neural substrates of visuospatial processing in distinct reference frames: Evidence from unilateral spatial neglect
Jared Medina,Vijay Kannan,Mikolaj A. Pawlak,Jonathan T. Kleinman,Melissa Newhart,Cameron Davis,Jennifer Heidler-Gary,Edward H. Herskovits,Argye E. Hillis +8 more
TL;DR: Evidence is provided that portions of the dorsal stream of visual processing, including the right supramarginal gyrus, are involved in spatial encoding in egocentric coordinates, whereas parts of the ventral stream (including the posterior inferior temporal gyrus) are involvement in allocentric encoding.
Unilateral neglect is more severe and common in older patients with right hemispheric stroke
Rebecca F. Gottesman,Jonathan T. Kleinman,Cameron Davis,Jennifer Heidler-Gary,Melissa Newhart,Vijay Kannan,Argye E. Hillis +6 more
TL;DR: Increasing age in patients with acute right hemispheric stroke significantly increases the odds of unilateral neglect as well as severity of neglect, independently of size of the stroke or NIH Stroke Scale score.

Speech and language functions that require a functioning Broca's area
Cameron Davis,Jonathan T. Kleinman,Melissa Newhart,Leila Gingis,Mikolaj A. Pawlak,Argye E. Hillis,Argye E. Hillis +6 more
TL;DR: Evidence is provided for the critical role of Broca's area in these language functions, at least in this individual who showed selective hypoperfusion and acutely impaired production of grammatical sentences, comprehension of semantically reversible sentences, spelling, and motor planning of speech articulation.

Ischemia in Broca Area Is Associated With Broca Aphasia More Reliably in Acute Than in Chronic Stroke
Elisa Ochfeld,Melissa Newhart,John Molitoris,Richard Leigh,Lauren L. Cloutman,Cameron Davis,Jennifer T. Crinion,Jennifer T. Crinion,Argye E. Hillis +8 more
TL;DR: The results indicate that the acute aphasia syndrome may allow the clinician to predict the compromised vascular territory, even when structural imaging shows only a small (or no) infarct.

Distinct mechanisms and timing of language recovery after stroke.
Samson Jarso,Muwei Li,Andreia V. Faria,Cameron Davis,Richard Leigh,Rajani Sebastian,Kyrana Tsapkini,Susumu Mori,Argye E. Hillis +8 more
TL;DR: Five participants who had structural, perfusion, and functional imaging utilizing spelling, reading, word generation, and picture naming tasks at acute and subsequent stages after ischaemic stroke illustrate different mechanisms of aphasia recovery or illustrate that reorganization of language acutely depends on individual variables in addition to size and site of stroke.
