Abstract

Long-lasting memories are most efficiently formed by multiple training sessions separated by appropriately timed intervals. A recent study revealed that expression of a transgene encoding an inhibitor of protein phosphatase 1 (PP1) in the forebrain enhanced memory formed during sub-optimal training. Thus, PP1 apparently constrains memory formation in the mouse. Furthermore, the report proposes that PP1 promotes forgetting.
