Aberrant axon initial segment plasticity and intrinsic excitability of ALS hiPSC motor neurons
Summary: Dysregulated neuronal excitability is a hallmark of amyotrophic lateral sclerosis (ALS). We sought to investigate how functional changes to the axon initial segment (AIS), the site of action potential generation, could impact neuronal ...

AMPA Receptor Phosphorylation and Synaptic Colocalization on Motor Neurons Drive Maladaptive Plasticity below Complete Spinal Cord Injury. [PDF]
Clinical spinal cord injury (SCI) is accompanied by comorbid peripheral injury in 47% of patients. Human and animal modeling data have shown that painful peripheral injuries undermine long-term recovery of locomotion through unknown mechanisms ...

Excitatory motor neurons are local oscillators for backward locomotion
Cell- or network-driven oscillators underlie motor rhythmicity. The identity of C. elegans oscillators remains unknown. Through cell ablation, electrophysiology, and calcium imaging, we show: (1) forward and backward locomotion is driven by different ...

In amyotrophic lateral sclerosis (ALS) some motor neurons degenerate while others survive. The molecular mechanisms underlying this selective vulnerability and resistance, respectively, are poorly understood.

State Variables of the Arm May Be Encoded by Single Neuron Activity in the Monkey Motor Cortex [PDF]
Revealing the type of information encoded by neurons activity in the motor cortex is essential not only for understanding the mechanism of motion control but also for developing a brain-machine interface.

Visuomotor Transformation in the Fly Gaze Stabilization System [PDF]
For sensory signals to control an animal's behavior, they must first be transformed into a format appropriate for use by its motor systems. This fundamental problem is faced by all animals, including humans.

A role for kinesin heavy chain in controlling vesicle transport into dendrites in Drosophila. [PDF]
The unique architecture of neurons requires the establishment and maintenance of polarity, which relies in part on microtubule-based transport to deliver essential cargo into dendrites.

In patients with motor neurone disease, progressively worsening breathlessness often coincides with deteriorating bulbar function, and this combination may lead to difficulties in swallowing and coughing and a risk of aspiration. Occasionally, chest infections cause life threatening respiratory failure.

Co-occurrence of TDP-43 mislocalization with reduced activity of an RNA editing enzyme, ADAR2, in aged mouse motor neurons. [PDF]
TDP-43 pathology in spinal motor neurons is a neuropathological hallmark of sporadic amyotrophic lateral sclerosis (ALS) and has recently been shown to be closely associated with the downregulation of an RNA editing enzyme called adenosine deaminase ...

Modulation of motor behavior by the mesencephalic locomotor region
Summary: The mesencephalic locomotor region (MLR) serves as an interface between higher-order motor systems and lower motor neurons. The excitatory module of the MLR is composed of the pedunculopontine nucleus (PPN) and the cuneiform nucleus (CnF), and ...
