Postural instability in a young dyslexic adult improved by Hebbian pulse-width modulated lighting [PDF]

arXiv, 2020
Postural stability is linked to vision in everyone, since when the eyes are closed stability decreases by a factor of 2 or more. However, in persons with dyslexia postural stability is often deficient even when the eyes are open, since they show deficits in motor as well as specific cognitive functions. In dyslexics we have shown that abnormal symmetry

Mitochondrial DNA disorders in neuromuscular diseases in diverse populations

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Neuromuscular features are common in mitochondrial DNA (mtDNA) disorders. The genetic architecture of mtDNA disorders in diverse populations is poorly understood. We analysed mtDNA variants from whole‐exome sequencing data in neuromuscular patients from South Africa, Brazil, India, Turkey and Zambia. In 998 individuals, there were two definite

Implications of holdfast availability and patchiness on juvenile seahorse (Hippocampus reidi) condition and welfare: Simulations in captivity

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 552-561, December 2022., 2022
Abstract Seahorses (Genus Hippocampus; Family Syngnathidae) are iconic fish characterised by tails with prehensile capabilities, which develop after the transition from planktonic to benthonic lifestyle. As a result, seahorses remain attached to vegetal structures or other elements most of the time, both in the wild and under rearing conditions. In the

Selective Effects of Postural Control on Spatial vs. Nonspatial Working Memory: A Functional Near-Infrared Spectral Imaging Study

Frontiers in Human Neuroscience, 2018
Background: Previous evidence suggests that postural control processing may be more related to spatial working memory (SWM) than to nonspatial working memory (NWM).

Cortical control of posture in fine motor skills: evidence from inter-utterance rest position

Frontiers in Human Neuroscience, 2023
The vocal tract continuously employs tonic muscle activity in the maintenance of postural configurations. Gamma-band activity in the sensorimotor cortex underlies transient movements during speech production, yet little is known about the neural control ...

Cortical control of postural responses [PDF]

Journal of Neural Transmission, 2007
This article reviews the evidence for cortical involvement in shaping postural responses evoked by external postural perturbations. Although responses to postural perturbations occur more quickly than the fastest voluntary movements, they have longer latencies than spinal stretch reflexes, suggesting greater potential for modification by the cortex ...

Amygdala Neurodegeneration: A Key Driver of Visual Dysfunction in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Visual disability in Parkinson's disease (PD) is not fully explained by retinal neurodegeneration. We aimed to delineate the brain substrate of visual dysfunction in PD and its association with retinal thickness. Methods Forty‐two PD patients and 29 controls underwent 3‐Tesla MRI, retinal spectral‐domain optical coherence tomography,

Cervical proprioception, postural control, and pain: unraveling the interconnected challenges in rheumatoid arthritis

Journal of Orthopaedic Surgery and Research
Background Rheumatoid arthritis (RA) is a chronic autoimmune disease that impairs proprioception and postural control, increasing fall risk and reducing quality of life.

Renormalization Group Analysis of a Quivering String Model of Posture Control [PDF]

, 2000
Scaling concepts and renormalization group (RG) methods are applied to a simple linear model of human posture control consisting of a trembling or quivering string subject to damping and restoring forces. The string is driven by uncorrelated white Gaussian noise intended to model the corrections of the physiological control system.

Behavior-Driven Synthesis of Human Dynamics [PDF]

arXiv, 2021
Generating and representing human behavior are of major importance for various computer vision applications. Commonly, human video synthesis represents behavior as sequences of postures while directly predicting their likely progressions or merely changing the appearance of the depicted persons, thus not being able to exercise control over their actual
