The Aphasia Laboratory is located in the
Department of Communication Sciences and
Disorders at the University of South Carolina
and is directed by Julius Fridriksson, Ph.D. The
research foci of the lab include: 1)
Understanding the neurophysiology of aphasia
recovery in stroke; 2) Understanding speech
motor perception in normal and disordered
populations (e.g. autism, stroke, etc.); 3)
Understanding the neural basis of motor speech
processing. Much of this research relies
on technologies such as MRI (including DTI, fMRI,
VBM, LSM) and transcranial magnetic stimulation
(TMS).

Our research is funded by the following grants
to Julius Fridriksson:
Current NIH Funding:
Principal investigator, “National Institute of
Deafness and other Communication Disorders.”
Neurological Predictors of Anomia Recovery in
Aphasia, (R01 DC008355. Funding period
4/1/2007-3/31/2012. Annual budget:
$225,000/year). This project investigates the
relationship between cortical integrity and
outcome of anomia treatment in patients with
aphasia.
Principal investigator, “National Institute of
Deafness and other Communication Disorders.” A
Unified Neuroanatomical Model of Speech
Perception and Production: Implications (R01
DC009571. Funding period 4/1/2009-3/31/2014.
Requested funding: $250,000/year). This project
will examine the neural mechanism supporting
speech perception and production. Special
emphasis will be placed on translating basic
research findings into treatment of apraxia of
speech and conduction aphasia. Joint PI: Chris
Rorden.
Co-investigator, “National Institute on
Neurological Disorders and Stroke.” Dissociating
Components of the Attentional Network in Neglect
(R01 NS054266 funding period:
8/1/2006-7/31/2011: $205,000/year). The purpose
of this grant is to investigate brain damage
associated with neglect in stroke patients. PI:
Chris Rorden
Completed funding:
Principal investigator, “National Institute of
Deafness and other Communication Disorders.”
Neurological Predictors of Aphasia Recovery (R03
DC005915 funding period: 8/1/03-7/31/07; total
funding: $225,000). The purpose of this study
was to investigate the relationship among
cerebral perfusion, lesion size, aphasia, and
left hemi-spatial neglect in early stroke.
Co-PI, “Anonymous donor.” Brain atrophy and
normal aging. (Funding period: 2006-2009; total
funding: $100,000). The purpose of this research
is to examine the relationship between white and
gray matter atrophy in the normally aging brain
and cognition. Co-PI: Leonardo Bonilha
Co-investigator, “National Institute on Aging.”
Processing Discourse Reference in Mind and
Brain, (R21 AG030445. Funding period:
5/1/2008-4/30/2010. Annual budget: $150,000).
This research aims to uncover the functional and
neural processes that underlie reference
comprehension, especially with respect to the
relation between reference form and referent
salience. PI: Amit Almor
