Researchers explain the goals of a new brain-mapping project

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 coordinated efforts scientists cannot currently track.

An article published Thursday in Science online expands the project’s already ambitious goals beyond just recording the activity of all individual neurons in a brain circuit simultaneously. Researchers should also  find ways to manipulate the neurons within those circuits and understand circuit function through new methods of data analysis and modeling.
