Duke University Medical Center researchers have identified a missing-link molecule that helps to explain the process of plasticity (rearranging neural connections in learning and forming memories) and could lead to new therapies.

The myosin Vb molecule moves new receptors to the synapse via actin filaments so that the neuron can respond more strongly and strengthen connections.

The finding may suggest new therapies for treating memory loss, psychiatric disease, and ways to improve brain development.
