Regeneration After a Stroke Requires Intact Communication Channels Between Brain Hemispheres

Summary:

The structure of the corpus callosum, a thick band of nerve fibres that connects the two halves of the brain with each other and in this way enables the rapid exchange of information between the left and right hemispheres, plays an important role in the regaining of motor skills following a stroke. A study by scientists from the Max Planck Institute for Neurological Research and the Department of Neurology at the University Hospital of Cologne currently published in the journal Human Brain Mapping has shown that in stroke patients with particularly severely impaired hand movement, this communication channel between the two brain hemispheres in particular was badly damaged.
