Excited to share our lab’s posters at @SfNtweets! Come check them out—covering how explicit strategies handle small motor errors, fundamental sensorimotor processes, computational mechanisms behind motor strategies, and the impact of Parkinson’s disease on motor adaptation.

New preprint!!! @TianHWang shows that attention influences sensorimotor adaption by defining the context for learning. Check it out! 👇 biorxiv.org/content/10.1101/…

Attention defines the context for implicit sensorimotor adaptation

Movement errors are used to continuously recalibrate the sensorimotor map, a process known as sensorimotor adaptation. Here we examined how attention influences this automatic and obligatory learning...

Fundamental processes in sensorimotor learning: Reasoning, refinement, and retrieval

The 3R framework outlines three fundamental processes in motor learning and provides a novel perspective on understanding how we acquire, adapt, and retain complex motor skills.

Differential Aging Effects on Implicit and Explicit Sensorimotor Learning

Deterioration in motor control is a hallmark of aging, significantly contributing to a decline in quality of life. More controversial is the question of whether and how aging impacts sensorimotor...

Motor adaptation is reduced by symbolic compared to sensory feedback

Motor adaptation – the process of reducing motor errors through feedback and practice – is an essential feature of human competence, allowing us to move accurately in dynamic and novel environments....

How should we interpret fMRI signal changes in the cerebellum? Learn about our new approach of how to better understand the relationship cerebellar and neocortical activity! @ivrylab @ladanshahani @MaedbhK @carobellum doi.org/10.7554/eLife.96386 @eLife

Selective recruitment of the cerebellum evidenced by task-dependent gating of inputs

The human cerebellum shows fMRI activity for many tasks – however, the inputs from the neocortex are upregulated in a task-dependent manner when cerebellar computation is required.

New preprint!!! @avraham_guy & @ivryrich address the question of why implicit motor adaptation shows attenuation upon relearning (anti-savings). biorxiv.org/content/10.1101/… Check it out! 👇

Interference underlies attenuation upon relearning in sensorimotor adaptation

Savings refers to the gain in performance upon relearning a task. In sensorimotor adaptation, savings is tested by having participants adapt to perturbed feedback and, following a washout block...

Question: Does the relevance of visual feedback influence how we subconsciously correct for errors in our movement? Answer: Yes! In our paper in @JOCN_Journal, we showed that *implicit* motor adaptation is modulated by the relevance of visual feedback. shorturl.at/jnoGM

Where does the motor bias originate? In this new preprint with @tsay_jonathan @rmhead @ivrylab, we show motor biases arise from the transformation of eye-centered visual information (where is the target) into hand-centric proprioceptive space during motor planning.
