Research Interests
Dr. Toga is interested in the development of
new algorithms and the computer science aspects important to neuroimaging. New
visualization techniques and statistical measurement are employed in the study
of morphometric variability in humans, subhuman primates and rodents.
His laboratory (Laboratory of
Neuro Imaging) has been working on the creation of three dimensional digital
neuroanatomic and functional neuroanatomic atlases for stereotactic
localization and multisubject comparison. Specific programs include the development
of local deformation techniques to equate brain data sets from different
modalities and different subjects and the development of electronic data bases
for the archival, interaction and distribution of brain data.
The
goal of the Laboratory of Neuro Imaging (LONI) is to improve the understanding
of the brain in health and disease. LONI develops novel strategies to
investigate brain structure and function in their full multidimensional
complexity. There is a rapidly growing need for brain models comprehensive
enough to represent brain structure and function as they change across time, in
large populations, in different disease states, across imaging modalities,
across age and gender, and even across species. A major focus of our research
is to develop 4D brain models that track and analyze complex patterns of
dynamically changing brain structure in development and disease, expanding
investigations of brain structure-function relationships to four dimensions.
