Consolidation in human motor memory

Article Abstract:

Consolidation of human motor skill involves neural processes that continue to encode and store information even after the task is learnt. The consolidation is time-dependent, with disruption being higher for tasks involving no time gap. Consolidation occurs when there is approximately a four-hour gap between the learning of two tasks. Learning and consolidation of motor skills may involve either the same or different synapses. The consolidation process of the motor skills is similar to that involved in the learning of explicit memory tasks.

Motor disorder in Huntington's disease begins as a dysfunction in error feedback control

Article Abstract:

Movement jerkiness, characterizing the smoothness and efficiency of motion, is a sensitive indicator of presymptomatic Huntington's disease (HD) progression.Asymptomatic HD gene-carriers (AGCs) showed elevated jerk, even if more than seven years remained until predicted onset of disease. The findings indicate a dysfunction in error correction, characterizing the motor control deficit in early HD.
