Wiring for Smell (image) Brown University Caption Native neurons (green) that express the odorant receptor MOR28 attach to known glomeruli (above). Neurons expressing engineered MOR28 (red) may attach to other glomeruli. Growing side-by-side, the red neurons could redirect some of the green, but only in the perinatal period. Neuron wiring established early remained stable in adults.
