Scientists have detailed how a combination of grafted replacement motor neurons and optical nerve stimulation—using light to activate neurons—can improve muscle function in a highly aggressive ...

Each muscle can have tens or hundreds of encapsulated sensory receptors, and these "sensors" are called muscle spindles. Spindles differ from other sensory receptors as they also receive nerve ...

Motor neurons are cells in your brain and spinal cord that help you walk, talk, and eat. Learn how damage to these cells could affect your movement and what your doctor can do to treat it.

Two genes, SMN1 and SMN2, are involved in production of survival motor neuron protein. SMN1 does most of the work to produce the full-length protein and is vital to motor neuron survival and function.

Symptoms of motor neuron degeneration could start at as early as 3 months of age and lead to muscle atrophy, paralysis and death, often before the child's second birthday.

Progressive bulbar palsy is a motor neuron disorder that involves the lower motor neurons. The first symptoms of progressive bulbar palsy are muscle weakness that affects speech and swallowing. It can ...

Motor neuron disease affects 5,000 adults in the U.K. at any one time and there is a 1 in 300 risk of getting MND across a lifetime. Once the disease progresses, it leads to the death of the motor ...
