Neuroscience researchers restore leg movement in primates

A Neural Bridge:  The	brain-spine interface developed for this study uses a brain implant like this one to detect spiking activity in the brain's motor cortex. Seen here, a microelectrode array and a silicon model of a primate's brain, as well as a pulse generator used to stimulate electrodes implanted on the spinal cord.

An international team of scientists, including BIBS faculty member David Borton, has used a wireless “brain-spinal interface” to bypass spinal cord injuries in a pair of rhesus macaques, restoring intentional walking movement to a temporarily paralyzed leg. The research is a step toward the development of a system that might help in rehabilitating people who have suffered spinal cord injuries.

Brown researchers developing new interactive sleep app

A group of Brown University computer scientists and clinical psychologists have come up with an approach that takes sleep monitoring one step further. The approach, dubbed SleepCoacher, uses sleep analytics to generate personalized recommendations informed by the scientific literature on sleep. SleepCoacher then guides users through a self-experimentation framework to help people find the recommendations that best work for them.

Brown launches new Data Science Initiative

Data Science at Brown:  Jeff Brock, director of Brown's new Data Science Initiative, stands in front of a topological map of attributes found in CT scans of traumatic brain injuries. Data analysis approaches like this could help to better categorize injury types and better tailor treatments for individual patients.

Brown University has launched a Data Science Initiative to catalyze new research programs to address some of the world’s most complex challenges and provide students with innovative educational opportunities relating to “big data.” The initiative builds on established strengths in mathematical and computational sciences and a long history of data-related research across its core academic departments.

Grant funds big-data study of brain connectivity

A complex organ:  A diagram of networks of gene expression in the brain produced by the research of biostatistician Xi Luo. With new grants from the BRAIN initiative, Luo will work with colleagues to develop ways of making sense of reams of "big data," including from brain imaging technologies.

With more than $1.2 million over three years to study how complex brain networks process information, Brown has earned its second grant this fall from the federal BRAIN Initiative and shares significantly in a third. BIBS faculty member Xi Luo and collaborators plan to tackle a big-data problem with complexities measured in the trillions — how the brain’s network connectivity makes it so good at information processing.
