A hormone, IGF-2, known to be a growth factor, improves memory and reduces forgetting. Researchers made the discovery with a discovery study in rats that received injections of the hormone in the hippocampus. The positive role of IGF-2 appears to be limited to a specific phase of memory: the consolidation of memories. This discovery, which remains to be confirmed in humans, paving the way to treatments stimulating the memory. Source: Nature, January 2011.
