Some brain areas, such as the olfactory bulb, can decorrelate (that is, separate out) very general inputs. However, the mechanisms enabling such decorrelation are unclear. This study presents a computational model that shows that efficient pattern decorrelation can emerge from a combination of nonlinear input-output functions and recurrent, sparse and strong inter-neuronal connectivity.
