Onasemnogene Abeparvovec in Type I Spinal Muscular Atrophy: 24‐Month Follow‐Up From the Italian Registry

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Onasemnogene abeparvovec (OA) is an AAV9‐based gene therapy for spinal muscular atrophy type I (SMA I). Real‐world outcomes show increased response variability compared to clinical trials, and follow‐up data beyond 12–18 months are limited.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

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

A structural motor network correlates with motor function and not impairment post stroke

Neuroscience Letters, 2017
Combining structural and functional magnetic resonance imaging may provide insight into how residual motor networks contribute to motor outcomes post-stroke. The purpose of this study was to examine whether a structural motor network (SMN), generated with fMRI guided diffusion-based tractography, relates to motor function post-stroke.

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.
