Researchers built a tool called LinCx that uses engineered proteins from white perch to forge electrical synapses between two specific cell types in a living mouse brain. Mutated to dock only with each other and not native connexins, the proteins let scientists connect cell type A to cell type B, something optogenetics and DREADDs cannot do. The work, published in Nature, opens a new way to rewire neural circuits.
