When humans and other mammals perform voluntary movements, a series of neural processes take place. The cerebral cortex, the outer region of the brain, sends signals to motor units (i.e., neurons) in the spinal cord, which ...
When adult humans and animals severely injure their spinal cord, they become irreversibly paralyzed and are no longer able to move body parts controlled by the section of the spinal cord below their lesion. To counteract ...
(Medical Xpress)—A recent perspective paper published in Science has raised some important, and timely, questions regarding neural diversity. The authors, from Columbia, MIT, and New York University, would simply like to ...
Humans and other mammals can produce a wide range of sounds, while also modulating their volume and pitch. These sounds, also known as mammalian vocalizations, play a central role in communication between both animals of ...
A research collaboration led by the University of Chinese Academy of Sciences, China, investigated the role of CHIT1, a protein associated with microglia, in aging.
Xiang-Dong Fu, Ph.D., has never been more excited about something in his entire career. He has long studied the basic biology of RNA, a genetic cousin of DNA, and the proteins that bind it. But a single discovery has launched ...

The mouse brain contains roughly 80 million neurons, all packed into a space about the size of a hazelnut. Those cells come in a vast assortment of shapes and sizes, and their connections with one another number in the billions—at ...

There is no cure for amyotrophic lateral sclerosis (ALS), a disease that gradually kills off the motor neurons that control muscles and is diagnosed in nearly 6,000 people per year in the United States.

To ensure that a mouse hears the sounds of an approaching cat better than it hears the sounds its own footsteps make, the mouse's brain has a built-in noise-cancelling circuit.

In vertebrates, the term motor neuron (or motoneuron) classically applies to neurons located in the central nervous system (or CNS) that project their axons outside the CNS and directly or indirectly control muscles. Motor neuron is often associated with efferent neuron, primary neuron, or alpha motor neurons.
