...latest achievement in this promising field is the work of Dr. Donald Stein and three colleagues at Clark University in Worcester, Mass. As reported in last week's issue of Science, the group attempted to restore mental functioning in 21 rats whose brains had been damaged by removal of large sections of the frontal cortex. This section of the brain is involved in the learning of complex spatial relationships. Typically, rats sustaining such a severe injury would take 18 days or more to master a maze that required them to alternate right and left turns in the correct order...
Before attempting to repair the brain damage, Stein's team waited a week to allow for the natural accumulation of healing proteins called nerve growth factors. Then they implanted a pinhead-size lump of tissue that had been taken from the frontal cortex of normal rat embryos. The researchers used fetal cells because they are rich in growth factors and adapt easily to a new environment. Result of the operation: the brain-damaged rats were able to learn the maze in just 8½ days. While this is still slower than normal, says Stein, "the transplant was clearly producing...
