A new technology called LinCx allows scientists to create custom electrical connections between neurons with high precision. Researchers say it may help treat disorders caused by damaged brain circuits.
Damage to brain circuits plays a major role in many neurological disorders. Researchers at Duke University School of Medicine have developed a custom biological “wire” that could offer a new treatment strategy by creating alternate pathways around damaged brain connections instead of relying on long-term medications or external stimulation.
The research team, led by Kafui Dzirasa, MD, PhD, created a technology called LinCx that allows scientists to build new electrical connections between selected neurons. Unlike many existing methods that affect large groups of cells, LinCx is designed to make targeted, long-lasting changes within specific brain circuits. The study was published in Nature.
“By introducing a way to plug in new electrical connections with cellular‑level precision, our study marks a major step forward in the ability to edit brain circuitry and understand how neural networks give rise to behavior,“ said Dzirasa, the A. Eugene and Marie Washington Presidential Distinguished Professor of Psychiatry & Behavioral Sciences, Behavioral Medicine & Neurosciences.
Instead of repairing damaged synapses, the method creates a new electrical “bypass” between specific neurons, improving communication without altering the brain’s existing connections.
Engineered Proteins Create Precision Neural Links
The system is built using proteins originally discovered in fish that naturally form electrical synapses. Researchers…
