But the effects of using light to control the nervous system so it's not as good because the brain does not respond to light that sent so. Team of researchers turned to genetic engineering techniques (genetic engineering) to help by making genetically modified protein derived from algae, are sensitive to light and then used a virus that has been genetically modified, and then sent a communication to the brains of rats. By altering the proteins are expressed on a cell, the BNST has the nerve signals to the hypothalamus, it only lacks side, La MAS.Afterward, Garret Stuber. transplantation of optic (fiber optic cable) into the brains of rats, the special breed. Researchers can send light through the glass fiber to the nerve ends BNST (BNST synapse) to stimulate the nerve signaling. When the light reached the nerve endings BNST rats began to eat greedily, although previously I would make food by multi-party, high fat diet, rats will be even more greedy. In just 20 minutes, those rats consuming food which provides enough calories for a half day. But when the scientists stopped the light stimulation Turns out that results had little interest in food only. Unlike the previous completely.
