How does the nervous system synchronize movements to catch a falling ball? According to one theory, only sensory information is used to estimate time-to-contact (TTC) with an approaching object; alternatively, implicit knowledge about physics may come into play. Here we show that astronauts initiated catching movements earlier in 0 g than in 1 g, which demonstrates that the brain uses an internal model of gravity to supplement sensory information when estimating TTC.

The use of on-line perceptual invariants versus cognitive internal models for the predictive control of movement and action
TLDR
This paper demonstrates how control strategies that rely on first-order, real-time estimates of time-to-contact can be tuned based on a priori knowledge about gravity to provide more effective control with little or no additional computations. Expand
Movement and Numbers: The Mathematics Behind Motor Actions
The scope of this mini review is to show as neuromotor control often applies mathematical principles and properties improving efficiency of movements. We reported four examples: harmony of humanExpand
Representation of Visual Gravitational Motion in the Human Vestibular Cortex
TLDR
It is found that the vestibular network was selectively engaged when acceleration was consistent with natural gravity, demonstrating that predictive mechanisms of physical laws of motion are represented in the human brain. Expand
Actual and Imagined Movements Reveal a Dual Role of the Insular Cortex for Motor Control.
TLDR
The posterior part of the insular cortex was engaged when feedback was processed and the anterior insula was activated only in mental simulation of the action, indicating a dual internal representation of gravity within the insula. Expand
Direction-dependent arm kinematics reveal optimal integration of gravity cues
TLDR
It is shown that the brain uses the internal model to implement control policies that take advantage of gravity to minimize movement effort, resulting in direction-depending kinematics. Expand
Integration of speed and time for estimating time to contact
TLDR
Results indicated that humans rely on both speed information and temporal cues and integrate them to optimize their TTC estimates when both cues are present, suggesting that the brain’s timing mechanisms are actively engaged when interacting with dynamic stimuli. Expand
A cross-species neural integration of gravity for motor optimisation
TLDR
This work analyzes muscular activation patterns during single-degree-of-freedom arm movements in various directions to demonstrate that phasic EMGs present systematic negative phases and reveals that the brain implements an optimal motor plan using gravity to accelerate downward and decelerate upward movements.

What you feel is what you see: inverse dynamics estimation underlies the resistive sensation of a delayed cursor

TLDR
The resistive sensation the authors experience while moving a delayed cursor, perceived purely from the change in visual motion, provides evidence of the inverse computation, i.e., the CNS automatically computes inverse dynamics, using visually detected motions, to monitor the dynamic forces involved in their actions. Expand
Visual gravitational motion and the vestibular system in humans
The visual system is poorly sensitive to arbitrary accelerations, but accurately detects the effects of gravity on a target motion. Here we review behavioral and neuroimaging data about the neuralExpand
Gravity highlights a dual role of the insula in internal models
TLDR
A dual internal representation of gravity within the insula is demonstrated and how they can conceptually be linked is discussed. Expand

This article describes an alternative approach that is based on recent data showing that the information used in judging time-to-collision is task- and situation-dependent, is of many different origins and is influenced by the information-processing constraints of the nervous system. Expand

Activity takes place in a space-time world. It therefore requires spatio-temporal information for its guidance. Where does this information come from? Since activity involves movement relative to theExpand
Sensory and intrinsic coordination of movement
TLDR
Kinematic analysis of hand to mouth movements by human adults, with eyes open or closed, indicated that hand guidance was achieved by maintaining, during 80 to 85% of the movement, the τ–couplings τα–τr and τr–τg, where τr is τ of the hand–mouth gap, τα isτ of the angular gap to be closed by steering the hand and τg is an intrinsic τ–guide.

Latency and gain of the rabbit's optokinetic reactions to small movements.
TLDR
The rabbit's optokinetic reactions to small movements of short duration were measured, using averaging techniques, and may indicate that a minimal displacement of the order of the inter-receptor distance on the retina is required for motion detection. Expand

Visual Timing in Hitting An Accelerating Ball
TLDR
To investigate the timing of actions relative to events in the environment, subjects leapt to punch a falling ball and analysed their knee and elbow angles as functions of time for three ball-drop heights, finding that the differences in the functions could be explained on the basis that the subjects were gearing their actions to a particular optic variable.

TLDR
It is argued that both the anticipatory and the reflex coactivation are centrally preset in preparation for catching and are instrumental for stabilizing limb posture after impact, demonstrating that anticipatory muscle stiffening and anticipatory flexion of the limb are synergistic in building up resistance of the hand to vertical displacement.

Catching balls: How to get the hand to the right place at the right time.
TLDR
Despite empirical support for the assumption that object size can serve as a metric in the perception of passing distance, the present series of experiments reveals that in catching a ball subjects do not rely on such "point-predictive" information. Expand
Weighted combination of size and disparity: a computational model for timing a ball catch
TLDR
A simple model is derived that uses both binocular disparity and optical looming to time hand closure to catch a ball and is sensitive to the relative effectiveness of size and disparity and implicitly switches its response to the cue that specifies the earliest arrival. Expand
