Biomolecular bonsai: Controlling the pruning and strengthening of neuron branches

How neuronal circuits remodel themselves over time, especially during early development, is a major question in neurobiology. Using mice, researchers have uncovered a biomolecular mechanism behind the strengthening of connections from neurons called mitral cells. The team found that the protein BMPR-2 is a key regulator of selective stabilization of neuron branching and that strengthening of a branch happens only when neural signals are transmitted.
