Is the homunculus “aware” of sensory adaptation?

P Seriès, AA Stocker, EP Simoncelli - Neural computation, 2009 - direct.mit.edu
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

B Wark, BN Lundstrom, A Fairhall - Current opinion in neurobiology, 2007 - Elsevier
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

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 …

Asymmetric dynamics in optimal variance adaptation

M DeWeese, A Zador - Neural Computation, 1998 - direct.mit.edu
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

HE Kim, JR Morehead, DE Parvin, R Moazzezi… - Communications …, 2018 - nature.com
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

JR Morehead, JA Taylor, DE Parvin… - Journal of cognitive …, 2017 - direct.mit.edu
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 …

[HTML][HTML] Visual adaptation: Neural, psychological and computational aspects

CWG Clifford, MA Webster, GB Stanley, AA Stocker… - Vision research, 2007 - Elsevier
The term visual adaptation describes the processes by which the visual system alters its
operating properties in response to changes in the environment. These continual …

[HTML][HTML] Perceptual learning

JI Gold, T Watanabe - Current biology, 2010 - cell.com
Magazine R47 since that time, with many studies designed to reveal the nature of the
underlying neural changes. Our understanding of the neural changes responsible for …

Explicit and implicit contributions to learning in a sensorimotor adaptation task

JA Taylor, JW Krakauer, RB Ivry - Journal of Neuroscience, 2014 - Soc Neuroscience
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 …
