Abstract: Memories made with precision Learning and memory tasks are associated with the addition of new synapses in the brain, but the function of this structural plasticity is not clear. A study of the rearrangement of circuits within the hippocampus and cerebellum in response to learning reveals a robust, long-lasting and reversible increase in the number of synapses that trigger feedforward inhibition. This synapse growth has a vital role in maintaining the precision of the memory and the learned behaviour.
