Grip Force Complexity Under Constraint: Evidence from Fractal and Entropy Analyses

This study examines how grip force and load force dynamics change under different task constraints using fractal and entropy analyses, finding increased temporal persistence and local irregularity under constraints.

Time-of-day effects on motor learning

This study shows that evening training leads to better skill consolidation compared to morning or afternoon training, with sleep contributing to this effect.

Visuo-motor rotation influences representational acuity but not space representation

The paper investigates how visuo-motor rotation affects representational acuity and spatial cognition, finding no cognitive after-effects but increased representational acuity after gradual exposure.

Gravity highlights a dual role of the insula in internal models

The paper investigates the role of the insula in processing gravity during movement, finding distinct activation patterns for predictive and reactive mechanisms.

Visual and auditory information shed light on savings mechanisms

The paper investigates how visual and auditory feedback influence motor learning and adaptation, finding that visual feedback leads to higher adaptation than auditory feedback, with transfer occurring through a memory of the learned reaching direction.

Does force-field adaptation induce after-effects on space representation?

The paper investigates whether force-field adaptation induces after-effects on space representation by comparing prism adaptation and dynamic environment adaptation in healthy individuals.

Smart switching in feedforward control of grip force during manipulation of elastic objects

The paper shows that grip force control during object manipulation involves a switch between two feedforward control strategies based on object stiffness.

Grip force adjustments reflect prediction of dynamic consequences in varying gravitoinertial fields

The paper shows participants adjust grip force based on expected gravity changes, using a combination of anticipation, safety factors, and feedback mechanisms.
