Dynamic Recruitment of the of the Cortex-To-Brainstem Pathways (image) Nagoya City University Share Print E-Mail Caption Stroke often destroys the cortico-spinal tract and causes hemiparesis. Nagoya City University researchers have revealed intensive rehabilitaion increases the "cortex-to-red nucleus" pathway and induces functional recovery via the circuit. However, there are some motor-related circuits in central nervous system other than the cortex-to-red nucleus pathway. The researchers clarified that alternative increase of the "cortex-to-reticular formation" pathway occurs when the cortex-to-red nucleus pathway fails to function during rehabilitation. The recruited cortex-to-reticular formation pathway had causal link to functional recovery induced by rehabilitation. Current results indicates that these dynamic recruitment of the cortex-to-brainstem pathways is a key factor for functional recovery in intensive rehabilitation after stroke.
