A proposed effort to map brain activity on a large scale, expected to be announced by the White House later this month, could help neuroscientists understand the origins of cognition, perception, and other phenomena. These brain activities haven’t been well understood to date, in part because they arise from the interaction of large sets of neurons whose coördinated efforts scientists cannot currently track.
“There are all kinds of remarkable tools to study the microscopic world of individual cells,” says John Donoghue, a neuroscientist at Brown and a participant in the project. “And on the macroscopic end, we have tools like MRI and EEG that tell us about the function of the brain and its structure, but at a low resolution. There is a gap in the middle. We need to record many, many neurons exactly as they operate with temporal precision and in large areas,” he says.
