Young Neurons Keep Quiet

Posted 12 Nov 2007 at 15:57 UTC by Rog-a-matic Share This

Yale School of Medicine researchers report in The Journal of Neuroscience that newly created neurons use signals from distant brain areas to control growth, programming, and connections before their outputs are used by the network. The purpose might be to prevent young neurons from disrupting function until they are ready to make a positive contribution. It's possible this idea could be incorporated into artificial neural nets to improve performance and to maintain stability during growth phases by allowing neurons to begin learning while their outputs are inhibited. After a certain time, cycle count, or training goal is reached, the cell could be integrated with the rest of the network.
