A cortico-cerebellar loop for motor planning [PDF]

Nature, 2018
Persistent and ramping neural activity in the frontal cortex anticipates specific movements1-6. Preparatory activity is distributed across several brain regions7,8, but it is unclear which brain areas are involved and how this activity is mediated by multi-regional interactions.

SPEECH IN RHYTHM OR WHY INTENSIVE AND INTERVAL THERAPY IN SPEECH THERAPY WORKS

Listy klinicke logopedie
Speech, movement, proper ontogenetic development of the individual, cognition, emotions, ability to learn, memory and the list could go on. All of these are directly dependent on balance, which is based on the rhythm realised at an optimal pace with ...

Feedforward control in children with cerebral palsy and association with white matter integrity

Frontiers in Neurology
BackgroundPrecise upper limb movements required for daily activities rely on feedback and feedforward control mechanisms. In children with cerebral palsy (CP), damage to white matter tracts impairs motor execution and sensorimotor control.

The Degree of Modulation of Beta Band Activity During Motor Planning Is Related to Trait Impulsivity

Frontiers in Integrative Neuroscience, 2019
Impulsivity is a prominent personality trait, and a key modulating component of neurologic and psychiatric disorders. How impulsivity is related to the brain mechanisms associated with action planning is poorly understood.

What Is in a Reach? Domain-General Spatial Modulation of Motor Responses by Number Representations

Journal of Numerical Cognition, 2017
Gaze, pointing, and reaching movements are thought to provide a window to internal cognitive states. In the case of numerical cognition, it has been found that the left-right deviation of a reaching movement is modulated by the relative magnitude of ...

Direction-dependent arm kinematics reveal optimal integration of gravity cues

eLife, 2016
The brain has evolved an internal model of gravity to cope with life in the Earth's gravitational environment. How this internal model benefits the implementation of skilled movement has remained unsolved.

Evidence for deficient motor planning in ADHD [PDF]

Scientific Reports, 2017
AbstractWe compare motor planning mechanisms of ADHD and control subjects based on their effect on later observed kinematic characteristics. We monitor hand movement following planning conditions that differ in preparation time, and evaluate the differences across conditions and participants with/without ADHD.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Eliciting End-State Comfort Planning in Children With and Without Developmental Coordination Disorder Using a Hammer Task: A Pilot Study

Frontiers in Psychology, 2021
The end-state comfort (ESC) effect refers to the consistent tendency of healthy adults to end their movements in a comfortable end posture. In children with and without developmental coordination disorder (DCD), the results of studies focusing on ESC ...

Anticipatory Motor Planning in Older Adults [PDF]

The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2015
The end-state comfort (ESC) effect represents an efficiency constraint in anticipatory motor planning. Although young adults usually avoid uncomfortable postures at the end of goal-directed movements, newer studies revealed that children's sensitivity for ESC is not fully in place before the age of 10 years.
