Caption: Two neighboring brain cells "talk" to one another by sending signals across a gap called a synapse. The more active the synapse during development, U-M researchers found, the more a protein called SIRP-alpha is cut loose from one cell, travels to the other, and helps stabilize the synapse for the future.
