Part 1 (of 3): A Closer Look at Recovery
Aphasia is a communication disorder that can affect a person's ability to use and understand spoken or written language.
It usually results from damage to the side of the brain dominant for language. For most people, who are right handed this is the left side.
To understand recovery processes in the brain, we are attempting to use functional MRI(magnetic resonance imaging) to uncover the anatomical organization of the human brain regions involved in
- understanding spoken and written words and sentences.
I plan to do this by studying people immediately after their stroke and then monitor their brain and language changes over the subsequent months and in some cases follow them up over several years.
This type of research may improve understanding of how brain areas reorganize after focal brain injury.
The results could have implications for both the basic understanding of brain function and the diagnosis and treatment of neurological diseases.
For example: Recent results show that following an extensive left hemisphere stroke good recovery of speech comprehension is dependent on activation in an area in the right hemisphere of the brain
