The cerebral cortex is organized into functional representations, or maps, defined by increased activity during specific tasks. In addition, the brain exhibits robust spontaneous activity with spatiotemporal organization that defines the brain’s functional architecture (termed functional connectivity). Task-evoked representations and functional connectivity demonstrate experience-dependent plasticity, and this plasticity may be important in neurological development and disease. An important case of this is in focal ischemic injury, which results in destruction of the involved representations and disruption of functional connectivity relationships. Behavioral recovery correlates with representation remapping and functional connectivity normalization, suggesting functional organization is critical for recovery and a potentially …
