mmature neurons transplanted into the brains of obesity-prone mice can prevent the animals from becoming so fat, according to a new study. The researchers caution that their experiment was never intended as a step toward treating obesity in humans, but they say it provides an important proof of principle that transplanted fetal cells can integrate themselves into an abnormal neural circuit and help restore its function. Other researchers say the work highlights both the promise and the challenges of developing cell therapies for complex brain disorders.

(Medical Xpress) -- As in broadband information technology, the nervous system transmits different messages simultaneously from one brain region to others. But how are messages retrieved at the other end without confusing them?

In a scientific first that potentially could shed new light on how signals travel in the brain, how learning alters neural pathways, and might lead to speedier drug development, scientists at Harvard have created genetically-altered neurons that...

Scientists have demonstrated for the first time ever that there are fetal brain developments that can be measured using functional magnetic resonance tomography in the womb.

Among the many hurdles to be cleared before human embryonic stem cells can achieve their therapeutic potential is determining whether or not transplanted cells can functionally integrate into target organs or tissues.
