(Futura) – An injury to one brain region rarely stays contained to a single spot. The consequences ripple outward, creating a broader impact that depends on the scale of the injury, the function of the damaged area, and the specific circuits connected to it. For instance, a stroke in a language center disrupts speech, whereas a sudden blow to a motor region impairs physical movement.
Recovery, however, does not rest on the injured tissue alone. Intact regions step in to compensate for losses, helping the brain settle into a new functional balance. In a foundational 2013 review on post-injury neuroplasticity, researcher Dr. Randolph J. Nudo, a neuroscientist at the University of Kansas Medical Center highlighted how this exact compensatory process is at the core of recovery. CONTINUE
