Here we argue that for cognition to be embodied and sometimes embedded, means that the cognitive faculty cannot be local-ized in a brain area alone. We review recent research on neural reuse, the 1 ⁄ f structure of human activ-ity, tool use, group cognition, and social coordination dynamics that we believe demonstrates how the boundary between the different areas of the brain, the brain and body, and the body and environment is not only blurred but indeterminate. In turn, we propose that cognition is supported by a nested structure of task-specific synergies, w...
