“Resting state connectivity as a predictor of aphasia”
Chris Rorden and Grigori Yourganov
University of South Carolina

Two months ago in this series Dorian Pustina described how different
neuroimaging modalities provide complementary explanatory power. Specifically,
he revealed that a combination of lesions, virtual tractography and resting
state data are able to outperform any of these modalities in isolation. This
finding is significant, as accurate predictions can in theory guide optimal
bespoke therapies. Further, this finding is intuitive, as these modalities
appear to be measuring different aspects of an injury. Unfortunately, in our
own datasets we were unable to replicate Dr Pustina's findings: resting state
tended to be a poor predictor and its prediction seemed to be largely
redundant with the simple lesion maps. This mystery led us to reevaluate our
resting state data processing and analysis. We discovered that traditional
processing steps that have proved robust in handling data from healthy adults
can have negative consequences when applied to data from individuals with
large chronic injuries. These methods can lead to paradoxical results or
simply emphasize the influence of the frank lesion. We outline a novel method
for processing these datasets that not only generates physiologically
plausible results but also provides better predictive power. This work
highlights the potential of this emerging modality as well as the ability of
this lecture series to impact our field.

C-Star Lecture Series:

The Center for the Study of Aphasia Recovery (C-STAR; http://cstar.sc.edu)
houses researchers who examine the effects of behavioral treatment, brain
stimulation, and residual brain function (brain plasticity) on recovery from
aphasia. C-STAR is a collaboration between researchers from the University of
South Carolina, the Medical University of South Carolina, Johns Hopkins
University, and the University of California, Irvine. The Center is funded
through the National Institute of Deafness and Communication Disorders (NIDCD)
grant #NIH P50 DC014664. Biweekly public lectures, given by members and guests
of C-STAR, are accessible live and online. Recordings of the lectures can be
viewed via C-STAR YouTube channel:
