Editing Muscle memory (section)

=== Consolidation deficit ===
A recent issue in motor memory is whether or not it consolidates in a manner similar to declarative memory, a process that involves an initial fragile learning period that eventually becomes stable and less susceptible to damage over time.<ref name = "Krakauer" /> An example of stable motor memory consolidation in a patient with brain damage is the case of [[Clive Wearing]]. Clive has severe anterograde and retrograde amnesia owing to damage in his temporal lobes, frontal lobes, and hippocampi, which prevents him from storing any new memories and making him aware of only the present moment. However, Clive still retains access to his procedural memories, to be specific, the motor memories involved in playing the piano. This could be because motor memory is demonstrated through savings over several trials of learning, whereas declarative memory is demonstrated through recall of a single item.<ref name = "Krakauer" />  This suggests that lesions in certain brain areas normally associated with declarative memory would not affect motor memory for a well-learned skill.
