A new tool in the fight against treatment-resistant depression could be on the horizon thanks to a Rice University professor.

Jacob Robinson, a professor of electrical and computer engineering and of bioengineering is also co-founder and CEO of Motif Neurotech. Created through the Rice Biotech Launch Pad, Motif Neurotech is focused on developing minimally invasive bioelectronics for the treatment of psychiatric conditions. The company closed its series A round with an oversubscribed $18.75 million earlier this year.

This week, Rice University announced that Robinson has published a peer-reviewed study in Science Advances describing his wireless device called the Digitally programmable Over-brain Therapeutic (DOT). The epidural cortical stimulator is 9 millimeters in width, meaning that it’s easily implantable but is powerful enough to send electrical stimulation to the brain through the dura, the membrane that protects the brain and spinal cord.

“It overcomes challenges by using a battery-free and wireless approach to create an implant that can deliver precise and programmable stimulation to the brain, without brain surgery,” Robinson explained in a press release.

The DOT stimulator is intended to send electrical charges meant to provide neuromodulation for mental health woes including not just depression, but also obsessive compulsive disorder and post-traumatic stress disorder. The treatment could be an alternative to transcranial magnetic stimulation (TMS), a technique that has increased in popularity in recent years.

TMS uses pulsed magnetic fields to stimulate the brain. A typical TMS course includes 36 total treatments and can cause headaches. The DOT stimulator can enact the same timing patterns used in TMS, such as the intermittent theta burst stimulation (iTBS) paradigm, which has been noted to improve mood in patients, but can be achieved at home with far greater ease. Implantation takes just 20 minutes.

So far, the DOT stimulator has been implanted in both a human and a pig. In the pig, researchers noted that the electrical stimulation did not cause any damage to the brain or dura. Just as importantly, it showed stable performance for 30 days in inducing motor responses, meaning it can operate on a longer-term basis.

Motif Neurotech was founded along with Kaiyuan Yang and physicians Sunil Sheth and Sameer Sheth. The Rice Biotech Launchpad brings together local researchers like Robinson and his team with a network of industry executives. With their manuscript, entitled “Miniature battery-free epidural cortical stimulators” freshly published on the Science Advances website, big things could be coming for the bioelectronics company and for sufferers of treatment-resistant depression.
