Bi‐ and Mono‐Allelic RFC1 Expansion in a North American Cohort With Idiopathic Axonal Neuropathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective RFC1 biallelic repeat expansion is increasingly recognized as a cause of chronic idiopathic axonal polyneuropathy (CIAP), but it remains challenging to know who to test. This study aims to determine the prevalence of biallelic and monoallelic RFC1 expansions and their corresponding neuropathy phenotypes in CIAP patients and identify ...

Factors Associated With the Rising Trend in Self‐Reported Cognitive Disability Among U.S. Adults Aged 18–39 From 2013–2024

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Building on our prior Behavioral Risk Factor Surveillance System analysis identifying adults aged 18–39 as the primary driver of the national increase in self‐reported cognitive disability, we examined factors associated with this rise using 2013–2024 U.S. BRFSS data. Methods We analyzed U.S.

Motor neural networks in the leech

Trends in Neurosciences, 2023
Leeches display robust motor patterns and exhibit a relatively simple nervous system where neurons are unambiguously identified. This brief article focuses on Hirudo verbana and summarizes how research in this organism has contributed to insights in the field of motor control, where networks have been studied from population down to individual neuron ...

Kinesin’s Network of Chemomechanical Motor Cycles

Physical Review Letters, 2007
A general network theory for the molecular motor kinesin is developed that is based on the distinct chemical states of the motor and on recent observations about its mechanical steps. For small concentrations of adenosine diphosphate (ADP), the motor's behavior is governed by the competition of two chemomechanical motor cycles which determine the motor'

Stabilization of motor networks

Proceedings of 1995 34th IEEE Conference on Decision and Control, 2002
In some cases the most important factor limiting the performance of a distributed control system is not the availability of computational power but rather the availablity of time on a shared communication network for communication between the sensors, the control computer and the actuators.

Simulation of a molecular motor based communication network

Proceedings of the 1st international conference on Bio inspired models of network, information and computing systems - BIONETICS '06, 2006
Molecular communication provides a mechanism for the coordination and control of micro-scale and nano-scale devices. In this paper, we describe simulation models to evaluate a molecular communication system that uses molecular motors to transport information molecules over a filament network.

Oscillation in motor pattern-generating networks

Current Opinion in Neurobiology, 1995
Oscillation in motor pattern generators is driven either by pacemaker neurons with inherent bursting properties or through network interactions. In a few examples in invertebrates and lower vertebrates, the mechanisms by which reciprocal inhibition combines with inherent membrane properties to produce network oscillation are beginning to emerge.

Motor network structure and function are associated with motor performance in Huntington’s disease

Journal of Neurology, 2016
In Huntington's disease, the relationship of brain structure, brain function and clinical measures remains incompletely understood. We asked how sensory-motor network brain structure and neural activity relate to each other and to motor performance. Thirty-four early stage HD and 32 age- and sex-matched healthy control participants underwent structural

Plasticity in the Motor Network Following Primary Motor Cortex Lesion

2013
The behavioral deficits following stroke are particularly evident in the fine control of force, movement, and posture of the arm and hand. However, functional recovery continues in the weeks and months after the initial lesion. Various animal models of stroke have been used to investigate the mechanisms involved with this recovery.
