Common movements, such as reaching and grasping an object or stepping, involve complex neural calculations to select the appropriate muscles and precisely control the timing of their contractions to ...

This study investigates changes in spinal excitability using peripheral nerve stimulation. We use the Hoffman reflex (H-reflex) to assess segmental changes following a neuroplasticity-priming ...

Two types of neurons that enable the spinal cord to control skilled forelimb movement have been found by researchers. The first is a group of excitatory interneurons that are needed to make accurate ...

How did the bodies of animals, including ours, become such fine-tuned movement machines? This paper cuts directly into critical debates about how the ancient spinal cord and the relatively new human ...

One hypothesis for the death of motor neurons in amyotrophic lateral sclerosis (ALS) is that the neurons become hyperexcited, firing overtime and ultimately being poisoned by their own activity (Rao ...

What is the cause of flexor and extensor spasms seen in patients with paraplegia? What is the prognosis in such patients? How do we manage such a problem? In a spinal cord injury resulting in ...

Spinal cord injuries caused by external trauma, such as traffic accidents or falls, often lead to the permanent loss of motor and sensory functions. This is because the spinal cord—the central pathway ...

Silent cells deep in your spinal cord may hold a surprising key to healing after devastating injuries and brain disease. A ...

Spinal deformities such as scoliosis and kyphosis are among the most serious complications of neurofibromatosis type 1 (NF1), a genetic disorder that affects about one in 3,000 people.

How did the bodies of animals, including ours, become such fine-tuned movement machines? How vertebrates coordinate the eternal tug-o-war between involuntary reflexes and seamless voluntary movements ...
