Investigating the role of functional modularity in language recovery
Brenda Rapp, PhD.
Johns Hopkins University

There is increasing interest in understanding how brain lesions affect the
coordination of neural activity between brain regions as well as in
understanding the role that changes in this functional connectivity may play
in recovery. fMRI, by measuring the activation time-courses of brain regions,
provides a basis for quantifying functional connectivity. Furthermore, graph
theoretic approaches provide an analytic tool for characterizing the
properties of the brain’s vast functional connectivity. Graph theoretic
analyses of functional connectivity have revealed that the brain is organized
into a non-random, modular structure consisting of densely inter-connected
clusters of brain regions. Characteristics of this functional modularity
structure have been linked to cognitive performance in healthy populations and
various neurological disorders. Therefore, understanding how lesions affect
modularity structure may provide critical insights into mechanisms of neural
plasticity. Computer simulations predict that lesions can have widespread
effects on the brain’s functional connectivity structure, however, relatively
little work has examined the consequences of actual lesions on functional
modularity.  I will review current research on the use of modularity and
related graph-theoretic measures in understanding aphasia and language
recovery, providing an example from our own research. Our findings illustrate
how analysis of the modularity characteristics of brain networks can increase
our understanding of post-stroke neural changes and the network reorganization
that supports recovery of function.

The lecture will be held at Johns Hopkins University. However, it will be
