[Shining light on translational research in deep brain stimulation]

Area of Science:

• Neuroscience
• Neuromodulation
• Translational Medicine

Background:

• Optogenetics has revolutionized neuroscience, enabling detailed circuit characterization in brain diseases such as addiction, depression, OCD, and anxiety disorders.
• Optogenetics has shown promise for novel therapeutic strategies, but direct human application is currently limited.

Purpose of the Study:

• To propose a roadmap for developing novel deep brain stimulation (DBS) protocols inspired by optogenetic findings.
• To bridge the gap between optogenetic research in animal models and potential human therapeutic applications.

Main Methods:

• Reviewing optogenetic studies and their implications for brain circuit modulation.
• Outlining a translational strategy for translating optogenetic principles into refined and novel DBS protocols.
• Identifying potential new indications for DBS based on optogenetic insights.

Main Results:

• Optogenetics provides a powerful tool for understanding neural circuits underlying brain disorders.
• Deep brain stimulation (DBS) offers a feasible intermediate step for human application of optogenetically inspired treatments.
• A framework is presented for developing rational, optogenetically informed DBS protocols.

Conclusions:

• Optogenetically inspired DBS protocols represent a promising translational approach for treating neurological and psychiatric disorders.
• This strategy can refine existing DBS therapies and expand their application to new indications.
• Further research is needed to fully realize the potential of optogenetically guided neuromodulation in humans.
