Motor neurons can be subdivided into lower motor neurons and upper motor neurons located in the brain and spinal cord. The ...

Upper motor neurons generally begin in the brain’s motor cortex and interact with spinal interneurons to initiate the neural circuits that generate movement. Lower motor neurons originate in the ...

(Upper motor neurons are those that travel from the cerebral cortex of the brain to the brainstem or spinal cord.) Hyporeflexia involves lower motor neurons that make up the peripheral nervous ...

New research shows that the adult brain can generate new neurons that integrate into key motor circuits, findings that may point to a new way to treat neurogenerative disorders. New research shows ...

Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS. Relay neurons connect sensory neurons to motor neurons. Motor neuron sends electrical ...

The disease process is characterized by axonal retraction and the subsequent loss of upper and lower motor neurons. This animation focuses on the mechanisms that drive ALS pathogenesis.

First described by Charcot over 125 years ago, the primary characteristic of this disease is the selective degeneration of upper and lower motor neurons, initiating in mid-adult life and almost ...

ALS is the most common form, involving both upper and lower motor neurons. It is a terminal degenerative disorder that causes people to lose the use of their limbs and the ability to speak ...

A new study published in the journal Cell Reports reveals that the adult brain can generate new neurons that integrate into key motor circuits—an insight that challenges long-held beliefs about ...
