A focus of Dr. Blumberg's laboratory is the use of brain scanning techniques to elucidate the differences in brain circuitry that underlie mood disorders, and how these differences develop. The laboratory has identified differences in parts of the brain that are important in emotional regulation in bipolar disorder, including differences in the pattern of their development in the disorder. For example, the laboratory has identified amygdala differences that are present in adults with bipolar disorder and also in adolescents with bipolar disorder suggesting that these are features that appear early, at least by adolescence in the disorder. Differences in the ventral prefrontal cortex (a part of the brain that includes the orbitofrontal cortex, the part of the prefrontal cortex above the eyes) appear to progress over the course of adolescence in bipolar disorder. This suggests that early intervention might be able to prevent progression and help prognosis. Preliminary evidence suggests treatment may reverse some of the brain differences and may have the potential to prevent this progression.
The lab is working intensively on genetic and environmental factors that may contribute to the differences in development and that may point to new prevention and treatment strategies. Brain scanning techniques used in this work include structural magnetic resonance imaging (MRI) to study the size and shape of brain structures, functional magnetic resonance imaging (fMRI) to study how the parts of the brain function individually and as part of brain circuits, and diffusion tensor imaging (DTI) to study the connections between brain structures.

Extensive Research Description
Dr. Blumberg is the Director of The Yale Mood Disorders
Research Program (MDRP). The MDRP is dedicated to understanding the science of mood
disorders, including bipolar disorder (manic-depressive illness) and
depression. The MDRP brings together a multi-disciplinary group of scientists
from across the Yale campus in a highly collaborative research effort. The scientists use a wide variety of scientific
methods to study how genetic and environmental factors affect the brain and
lead to the development of mood disorders. Goals of the MDRP include the
identification of biological markers for mood disorders and discovery of new
treatment strategies. It is hoped that these research efforts will lead to new and
improved methods for early detection and treatment, and someday prevention, of
