Motor Skill Consolidation
Motor Skill Consolidation represents the process by which motor skills are transformed from an initial fragile state, in which they are especially prone to being disrupted or lost, to a more solid or permanent state.〔Brashers-Krug T, Shadmehr R, Bizzi E., Consolidation in human motor memory. Nature. 1996 Jul 18;382(6588):252-5.〕 Any newly formed motor skill, such as learning to play a musical instrument or adjusting one's running stride, is subject to a consolidation period. The time course of this period during which new motor skills are susceptible to disruption appears to be on the order of a few hours.〔〔Press DZ, Casement MD, Pascual-Leone A, Robertson EM. The time course of off-line motor sequence learning. Brain Res Cogn Brain Res. 2005 Sep;25(1):375-8.〕
==Distinctions between Procedural and Declarative Memories==
Motor skills, also known as procedural memories, are distinct from declarative memories, which involve memories of events, people, places, etc. Both types of memories are, however, subject to a consolidation period, though the neural mechanisms appear to differ. Some of the earliest evidence pointing to a distinction between procedural and declarative memories came from the famous neurology patient HM. As a treatment for severe epilepsy, portions of HM's temporal lobes, including both hippocampi, were removed. This left him unable to form new declarative memories (anterograde amnesia), while his ability to learn novel motor tasks remained intact.〔Corkin S. What's new with the amnesic patient H.M.? Nat Rev Neurosci. 2002 Feb;3(2):153-60.〕
