Abstract: Methods have been developed for alleviating memory problems or psychiatric dysfunctions that have a memory formation component. These methods are based on the finding that a truncated form of an aPKC? protein is intimately involved in memory formation in animals. This finding is also central to methods for determining drugs that will have an effect on memory formation or the memory formation component of psychiatric dysfunctions.
