Wireless, implantable device stimulates nerves in mice

This method is typically sizeable and can cause problems for the mouse in terms of it’s mobility through its dugout or other closed spaces.



Before people go around thinking they could control other people’s minds, an important point must be done from clarifying that optogenetics is only successful on carefully prepared nerves that now contain proteins that respond to light. Powering the device was.

Using light, researchers will now be able to stimulate a mouse’s brain nerves, which means no long wire hookups allowing mice to move with much more freedom of motion during experiments, or even experiments with multiple mice, or those involving tunnels, according to a UPI report. In these types of experiments, a mouse would move around a relatively large area, and the scientists needed a way of tracking these movements to provide localized power.

Studies of mice using optogenetics have uncovered secrets about Parkinson’s tremors, the mechanics of pain, and possible stroke treatments.

It is these issues that have prevented optogenetics from being used successfully to investigate mental issues, such as stress, depression and anxiety.

Ada Poon, an assistant professor of electrical engineering at Stanford University, said the device’s development is good for research overall because other researchers can use it – the design of the power source is publicly available and the device is easily customized.

This mouse’s own body transmits energy to an implantable device that delivers light to stimulate leg nerves in a Stanford optogenetics project. She and Yuji Tanabe, a research associate in her lab, then travelled to Japan to do the initial assembly and testing.

Earlier this year, Medical News Today reported how an optogenetics method was used to create an artificial link between unrelated memories in mice. So if something like, say, a mouse paw were present, it would come in contact with the boundary of all that stored energy. A honeycomb grid was laid on top of the chamber to counter this, enabling the energy to remain contained inside the chamber. Instead, the mouse becomes a conduit for the energy because of the exact wavelength that resonates within their body. The device is small, and the mouse will have little discomfort added Poon. The device is the first to deliver optogenetic nerve stimulation in a “fully implantable format”.

The team said the device and the novel powering mechanism open the door to a range of new experiments to better understand and treat mental health disorders, movement disorders and diseases of the internal organs.
