Is the homunculus “aware” of sensory adaptation?
Neural activity and perception are both affected by sensory history. The work presented here
explores the relationship between the physiological effects of adaptation and their …

Sensory adaptation
Adaptation occurs in a variety of forms in all sensory systems, motivating the question: what
is its purpose? A productive approach has been to hypothesize that adaptation helps neural …

Minimizing precision-weighted sensory prediction errors via memory formation and switching in motor adaptation
Y Oh, N Schweighofer - Journal of Neuroscience, 2019 - Soc Neuroscience
Humans predict the sensory consequences of motor commands by learning internal models
of the body and of environment perturbations. When facing a sensory prediction error …

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

Asymmetric dynamics in optimal variance adaptation
It has long been recognized that sensory systems adapt to their inputs. Here we formulate
the problem of optimal variance estimation for a broad class of nonstationary signals. We …

[HTML][HTML] Invariant errors reveal limitations in motor correction rather than constraints on error sensitivity
Implicit sensorimotor adaptation is traditionally described as a process of error reduction,
whereby a fraction of the error is corrected for with each movement. Here, in our study of …

Characteristics of implicit sensorimotor adaptation revealed by task-irrelevant clamped feedback
Sensorimotor adaptation occurs when there is a discrepancy between the expected and
actual sensory consequences of a movement. This learning can be precisely measured, but …

Explicit and implicit contributions to learning in a sensorimotor adaptation task
Visuomotor adaptation has been thought to be an implicit process that results when a
sensory-prediction error signal is used to update a forward model. A striking feature of …
