Stanford Scientists Create Implantable Device With Optogenetic Nerve Stimulation For Neuroscietific Research

Scientists at the Stanford Bio-X have developed a fully implantable device that offers optogenetic nerve stimulation. The new device which is powered by movement provides a promising and better opportunities for advance neuroscientific research.

The researchers were able to implant the device inside the mouse after removing the external equipment. The mouse can still move freely even with the implanted device. Light control and monitor neurons are used in optogenetic methods. Experts believe that the new discovery is the best to be used to further study brain functions.

The scientists used optogenetics through the mice to study the mechanics of brain failures and their corresponding psychiatric disorders. They were able to uncover the secrets about the Parkinson's disease, possible stroke treatments and the mechanics of pain.

Through the optogenetic system Ada Poon and from Stanford University her team were able to manipulate the brain of the mouse involved in their study about anxiety and depression. They also get to control the spinal cord including the mouse's peripheral nerve endings.

The authors of the study stated that, "This technology opens the door for optogenetic experiments in which animals are able to behave naturally with optogenetic manipulation of both central and peripheral targets."

Compared to the previous system that the team used in their study, the new device is smaller and easy to use. The small system was made possible through the novel power source. The new invention delivers wireless power for optogenetics. The mouse that is to be studied can still move around during experiments which is also necessary in conducting observations.

The human brain, which is the most complicated structure in biology and in the universe can now be understood with the help of the optogenetic system. Understanding how the brain works can aid scientists find cure for the brain problems that are affecting millions of people.
