Adult Brain Repair of Neural Damage

Abstract

Azhar Noor*

The brain is always at risk of injury, whether it is acute or chronic. The capacity for regeneration in the adult mammalian brain has long been thought to be severely limited when compared to other tissues such as the skin, liver, or intestines. As a result, the mammalian brain is unable to rebuild structures that have been lost due to harmful events such as ischemic stroke or traumatic brain injury. With acute or chronic injury, however, there is significant functional restoration due to the ability of surviving brain structures to take up at least some of the functions of destroyed tissues. This is seen, for example, in patients who have left-hemispheric strokes and may initially exhibit motor or sensory aphasia.
