TY - JOUR PY - 2014// TI - A memory of errors in sensorimotor learning JO - Science A1 - Herzfeld, David J. A1 - Vaswani, Pavan A. A1 - Marko, Mollie A1 - Shadmehr, Reza SP - 1349 EP - 1353 VL - 345 IS - 6202 N2 - The current view of motor learning suggests that when we revisit a task, the brain recalls the motor commands it previously learned. In this view, motor memory is a memory of motor commands, acquired through trial-and-error and reinforcement. Here, we show that the brain controls how much it is willing to learn from the current error through a principled mechanism that depends on the history of past errors. This suggests that the brain stores a previously unknown form of memory, a memory of errors. A mathematical formulation of this idea provides insights into a host of puzzling experimental data, including savings and meta-learning, demonstrating that when we are better at a motor task, it is partly because the brain recognizes the errors it experienced before.
