Two Brown University faculty members have received federal funding for innovative new neuroscience research projects focusing on brain development in infants and bipolar disorder in children.
Sean Deoni, assistant professor of engineering, plans to use his $2.5-million grant to study neurodevelopment throughout infancy and early childhood, from 2 months to age 5, using an MRI imaging technique at Brown he previously developed with colleagues.
Dr. Daniel Dickstein, assistant professor of psychiatry and human behavior at Alpert Medical School and head of the Pediatric Mood, Imaging and Neurodevelopment (Pedi-MIND) program at Bradley Hospital, has been awarded a $1.87-million grant to identify biological and behavioral markers that distinguish between development of full-blown and sub-syndromal bipolar disorder. Most of Dickstein's research will take place at Bradley Hospital. The Pedi-Mind research program uses cutting-edge techniques including brain-imaging, behavorial tasks and genetic analyses to identify biological markers of psychological illness.
Both grants come through the National Institute of Mental Health's (NIMH) BRAINS program and will span five years. Only seven BRAINS grants - Biobehavioral Research Awards for Innovative New Scientists - were awarded nationally in 2009, the program's inaugural year.
Deoni and Dickstein are affiliated with the Brown Institute for Brain Science.
Deoni will study myelination, a process that is central to establishing efficient communication pathways throughout the brain. Myelination is the formation of the fatty myelin layer around brain neurons and fibers. Abnormal myelination can lead to disorders that affect walking, movement, communication, decision making and other functions. Scientists believe abnormal myelination can contribute to neurodevelopmental disorders including autism, schizophrenia and developmental delay.
