Netrin is known to help set up the healthy nervous system in an infant’s developing brain by directing brain cells to make appropriate connections with other brain cells.

“A huge step forward in identifying how the brain makes and stores memories. Our research demonstrates that Netrin is critical for changes in the strength of connections between brain cells, and offers a new, previously undiscovered target for diseases that affect memory function.”
