Picower Institute for Learning and Memory, a branch of MIT, has recognized an insulin-like growth factor. According to a research, it puts off the natural effects of visual deficiency in the brain.
This insulin-derived growth factor 1 (IGF1) may control links among neurons in the developing brain. It can be possible in the adult brain too. The lost or injured brain cell links can be cured. The disturbed connections among brain cells by the disease like Alzheimer can have a possible cure.
