In addition to ALS, upper motor neuron degeneration also results in other motor neuron diseases, such as hereditary spastic paraplegia (HSP) and primary lateral sclerosis (PLS).

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.

Primary lateral sclerosis is a rare condition that causes upper motor neurons, which control movement, ... they have gradual onset and progression of upper motor neuron signs, such as spasticity ...

PLS is a rare form of motor neuron disease that primarily affects the upper motor neurons. In contrast, ALS is the most common form of motor neuron disease that affects both the upper and lower ...

Figure 1 | Stimulating a single motor neuron results in different movements depending on the posture of the fly’s head. a, b, The pitch (nodding) movement of a fly head when a motor neuron (CvN7 ...

Thus, the lower motor neuron activity is in part controlled by the upper motor neurons. Ozdinler and colleagues will now complete more detailed toxicology and pharmacokinetic studies prior to ...

The upper motor neuron begins in the brain and ends in the spinal cord. ... and an inability to control movement. Most mutations change amino acids in the TDP-43.

The findings were published in Nature in the paper, “Motor neurons generate pose-targeted movements via proprioceptive sculpting. “This is one of the first times scientists have analyzed in 3D ...
