Changes of brain activity that occur to take over motor functions lost due to brain lesion

March 19, 2015

A research collaborative has revealed the changes in the brain that occur to take over motor functions that were lost due to brain lesion.

The researchers generated permanent lesions in the cerebral motor cortex in model animals and investigated changes in brain activity during the recovery process of motor function through rehabilitation. As a result, they discovered that the activity of the remaining brain areas, the ventral premotor cortex and the perilesional primary motor cortex, was changed and that those areas had taken over the function of the lesioned area. This result could be a key to developing neurorehabilitation, which is a new rehabilitative method based on the mechanisms of brain functions.
