Motor planning under uncertainty. [PDF]
Elife, 2021 Actions often require the selection of a specific goal amongst a range of possibilities, like when a softball player must precisely position her glove to field a fast-approaching ground ball. Previous studies have suggested that during goal uncertainty the brain prepares for all potential goals in parallel and averages the corresponding motor plans to ...

Kinematic Changes in the Uninjured Limb After a Traumatic Brachial Plexus Injury
Frontiers in Human Neuroscience, 2021 Background: Traumatic brachial plexus injury (TBPI) typically causes sensory, motor and autonomic deficits of the affected upper limb. Recent studies have suggested that a unilateral TBPI can also affect the cortical representations associated to the ...

Effect of motor planning on use of motor abundance [PDF]
Neuroscience Letters, 2007 This study examined the hypothesis that the degree to which motor redundancy is used to coordinate joint motions for reaching is influenced by motor planning and enhanced when the task requires greater movement flexibility. Subjects reached at arm's length to the same centrally placed target under conditions where the target location was either certain

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.
