Summary: Rehabilitation is often prescribed after brain injury, but the basis for how training can influence brain plasticity and recovery is unclear. In this study, the authors show that intense rehabilitation training after focal brain injury drives significant structural changes in brain cells located adjacent to the injury. Importantly, a key brain modulatory system, the basal forebrain cholinergic system, is required for enabling rehabilitation to impact brain structure. Rats underwent cholinergic ablations by injecting 192-IgG-Saporin (Cat. #IT-01) into the nucleus basalis (0.2-0.25 mcl of 0.375 mg/ml solution in artificial CSF). Damage to the cholinergic system, which can occur naturally during aging, completely blocks brain plasticity mediated by rehabilitation and significantly attenuates functional recovery. These results provide new insights into how rehabilitation may promote recovery and suggest that brain cholinergic systems may be a possible therapeutic target for influencing recovery.
