Brain injury patients are sometimes deliberately placed in a coma with anesthesia drugs to allow swelling to go down and their brains to heal. Comas can last for days, during which patients’ brain activity must be regularly monitored to ensure the right level of sedation. The constant checking is “totally inefficient,” says Emery Brown, an anesthesiologist at Massachusetts General Hospital (MGH) and a professor in MIT’s Department of Brain and Cognitive Sciences. Brown and his colleagues at MGH have developed a “brain-machine interface” that automatically monitors brain activity and adjusts drug dosages accordingly. They’ve tested the system on rats and are now planning human trials.

Explore Professor Brown’s research in the Open Access Articles collection in DSpace@MIT, where it is openly accessible to the world.

Since the MIT faculty established their Open Access Policy in March 2009 they have made thousands of research papers freely available to the world via DSpace@MIT. To highlight that research, we’re offering a series of blog posts that link news stories about scholars’ work to their open access papers in DSpace.
