Motor Planning, Not Execution, Separates Motor Memories [PDF]
Neuron, 2016 Recent theories of limb control emphasize motor cortex as a dynamical system, with planning setting the initial neural state, and execution arising from the self-limiting evolution of the intrinsic neural dynamics. Therefore, movements that share an initial trajectory but then diverge might have different neural states during the execution of the ...

Brain Sciences, 2021 In two studies, we examine the test-retest reliability and factor structure of the computerized Tower of London (TOL) and Go/No Go (GNG). Before analyses, raw results of variables that were not normally distributed were transformed.

A switching cost for motor planning [PDF]
Journal of Neurophysiology, 2016 Abstract Movement planning consists of choosing the endpoint of the movement and selecting the motor program that will bring the effector on the endpoint. It is widely accepted that movement endpoint is updated on a trial-by-trial basis with respect to the observed errors and that the motor program for a given movement follows the rules

Upper limb joint coordination preserves hand kinematics after a traumatic brachial plexus injury
Frontiers in Human Neuroscience, 2022 BackgroundTraumatic brachial plexus injury (TBPI) causes a sensorimotor deficit in upper limb (UL) movements.ObjectiveOur aim was to investigate the arm–forearm coordination of both the injured and uninjured UL of TBPI subjects.MethodsTBPI participants ...

End-state comfort effects in adults with intellectual disabilities: A pilot study
Cogent Psychology, 2021 This study investigated the end-state comfort (ESC) effect in adults with intellectual disabilities (ID). The ESC effect represents a tendency to maximize comfortable hand and arm postures at the end of an object manipulation task.

The Importance of Planning in Motor Learning [PDF]
Neuron, 2016 The addition of differentiating follow-through motions can facilitate simultaneous learning of multiple motor skills that would otherwise interfere with each other. In this issue of Neuron, Sheahan and colleagues (2016) demonstrate that it is the preparation, not execution, of different follow-through movements that separates motor memories and reduces

The attraction effect in motor planning decisions
Judgment and Decision Making, 2015 In motor lotteries the probability of success is inherent in a person’s ability to make a speeded pointing movement. By contrast, in traditional economic lotteries, the probability of success is explicitly stated.

The Role of Inertial Sensitivity in Motor Planning [PDF]
The Journal of Neuroscience, 1998 To achieve a given motor task a single trajectory must be chosen from the infinite set of possibilities consistent with the task. To investigate such motor planning in a natural environment, we examined the kinematics of reaching movements made around a visual obstacle in three-dimensional space.

Aging Effect on Visuomotor Adaptation: Mediated by Cognitive Decline
Frontiers in Aging Neuroscience, 2021 The question of whether and how aging affects humans’ visuomotor adaptation remains controversial. This study investigates how the effect of aging on visuomotor adaptation is related to age-related cognitive declines.
