A team of neuroscientists and bioengineers from MIT’s Department of Brain and Cognitive Sciences and Center for Biomedical Engineering have been able to partially restore the vision of rodents whose visual neural pathways had been severed by injecting them with a tiny, biodegradable substrate on which brain cells were able to regrow and reconnect. The research marks the first time that nanotechnology has been used to heal a damaged brain region and restore lost functionality. The results could lead to major advancements in the treatment of traumatic brain and spinal cord injuries and strokes.

A mouse

It was announced yesterday that in an effort to create better models for studying neurological disorders, a team of scientists from the Salk Institute led by Dr. Fred Gage have successfully bio-engineered mice to be born with a small percentage of human brain cells. The process involves injecting 2-week-old mouse embryos with roughly 100,000 human embryonic stem cells. The mice created could be a valuable asset to scientists as they struggle to understand and combat neurological disorders like epilepsy and Parkinson’s disease.
