Abstract

Synapse structure in memory: plasticity and stability Connections between neurons are thought to be remodelled when we learn new tasks or acquire new information. However, this plasticity must also occur against a backdrop of stable memory maintenance. In mice, a paradigm of either enhanced sensory experience or specific motor learning produced new putative neuronal connections that remained stable alongside developmentally preserved connections much later in life. This suggests that learning can produce changes in the neuronal connectivity that can be stable for the lifetime of the network.
