A memory of errors in sensorimotor learning

DJ Herzfeld, PA Vaswani, MK Marko, R Shadmehr - Science, 2014 - science.org
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 …

Modulating locomotor adaptation with cerebellar stimulation

G Jayaram, B Tang, R Pallegadda… - Journal of …, 2012 - journals.physiology.org
Human locomotor adaptation is necessary to maintain flexibility of walking. Several lines of
research suggest that the cerebellum plays a critical role in motor adaptation. In this study …

[HTML][HTML] Reexposure to a sensorimotor perturbation produces opposite effects on explicit and implicit learning processes

G Avraham, JR Morehead, HE Kim, RB Ivry - PLoS biology, 2021 - journals.plos.org
The motor system demonstrates an exquisite ability to adapt to changes in the environment
and to quickly reset when these changes prove transient. If similar environmental changes …

[PDF][PDF] Spatial and temporal locomotor learning in mouse cerebellum

DM Darmohray, JR Jacobs, HG Marques, MR Carey - Neuron, 2019 - cell.com
Stable and efficient locomotion requires the precise coordination of movement across the
limbs and body. Learned changes in interlimb coordination can be induced by exposure to a …

An implicit memory of errors limits human sensorimotor adaptation

ST Albert, J Jang, HR Sheahan, L Teunissen… - Nature human …, 2021 - nature.com
During extended motor adaptation, learning appears to saturate despite persistence of
residual errors. This adaptation limit is not fixed but varies with perturbation variance; when …

Did we get sensorimotor adaptation wrong? Implicit adaptation as direct policy updating rather than forward-model-based learning

AM Hadjiosif, JW Krakauer, AM Haith - Journal of Neuroscience, 2021 - Soc Neuroscience
The human motor system can rapidly adapt its motor output in response to errors. The
prevailing theory of this process posits that the motor system adapts an internal forward …
