Intact communication channels between two halves of the brain are vital for regeneration following a stroke, a new study asserts.
Researchers at the University Hospital of Cologne discovered that the structure of the corpus callosum plays an important role in regaining motor skills after a stroke.
A combination of two imaging methods revealed that the corpus callosum of stroke patients is badly damaged and affects an individual's motor skills.
Christian Grefkes, head of the research study, stated: "The increased activity in the healthy brain hemisphere, in particular, points to the impaired processing of motor programs between the two brain hemispheres."
Aging is also thought to contribute to the breakdown of corpus callosum functioning, resulting in slower physical reactions.
A study at the University of Michigan revealed that resting cross-talk in the corpus callosum is not helpful or compensatory for the two halves of the brain to communicate during one-sided motor movements.
When both sides of the brain talk simultaneously while one side of the body is moving, confusion and slower responses occur.
