Inside the brain, an unpredictable race -- like a political campaign -- is being run. Multiple candidates, each with a network of supporters, have organized themselves into various left- and right-wing clusters -- like grassroots political teams working feverishly to reinforce a vision that bands them together. While scientists know that neurons in the brain anatomically organize themselves into these network camps, or clusters, the implications of such groupings on neural dynamics have remained unclear until now.
