Carnegie Mellon University research shows how sensory-deprived brain compensates
Whiskers provide a mouse with essential information to negotiate a burrow or detect movement that could signal a predator's presence. These stiff hairs relay sensory input to the brain, which shapes neuronal activity. In a first, studies of this system by Carnegie Mellon scientists show just how well a mouse brain can compensate when limited to sensing the world through one whisker.

Researchers have pinpointed in humans how a "backup" brain region springs into action to compensate for disruption of a primary functional area, as happens during stroke. Their finding offers new insight into how the brains of stroke victims can quickly reorganize to enable the beginning of recovery of movement. Jacinta O'Shea and colleagues at the University of Oxford reported their findi...
