If you have upper motor neuron lesions, you have damage to certain nerve cells that help you move. Medicines and therapy can help control symptoms like muscle spasms and help you walk and talk more ...

The scientist Stephen Hawking lived with amyotrophic lateral sclerosis (ALS), the most common type of motor neuron disease, ...

A small molecule known as 10H-phenothiazine reduced the loss of motor neurons, the nerve cells that are lost in SMA, in ...

(MEMPHIS, Tenn. – October 29, 2025) Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and hereditary spastic paraplegia (HSP), share physical similarities but have been largely viewed ...

Motor neurons are some of the largest cells in the human body. In particular, upper neurons—extending from the cerebral cortex to the brain stem or spinal cord—average 60μm in diameter. 3,4 These ...

A drug typically used to treat enlarged prostates and high blood pressure has shown promise as a potential new therapy for motor neuron disease (MND) -- also known as amyotrophic lateral sclerosis ...

When triggered by an odor, rapid changes in membrane voltage and intracellular calcium ion levels occur in nematode olfactory neurons, causing membrane voltage sensors and calcium ion sensors to ...

The discovery that tissues use electricity to expel unhealthy cells is part of a surge of renewed interest in the currents ...

Neurons are the specialized cells that allow our bodies to transmit impulses, like factories that process inputs. They send signals that help us catch a ball, recognize a favorite song or pull our ...

Our bodies’ nerve cells are important for transmitting electrical and chemical information between different parts of the brain and between the brain and other parts of the nervous system. One of the ...
