Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons. Sympathetic neurons are frequently considered part of the peripheral ...

Once dismissed as “junk,” a group of RNA molecules has been found to help regrow damaged nerves in mice in new research. The ...

Four Fun Facts About Your Peripheral Nervous System ... But did you know that parts of you that you thought were in your PNS—the light sensing retinas of your eyes—are actually brain tissue?

“Our work unveils the ontogeny, evolution, and neuron size regulatory functions of PNS microglia,” said Dr. WU Zhisheng, first author of the study. Reference: Wu Z, Wang Y, Chen W wei, et al.

Glial cells are an integral part of the human nervous system. They help support and nourish nerve cells, or neurons. Several types of glial cells exist. Glial cells are the “glue” of the ...

Unlike the brain and spinal cord, peripheral nerve cells, whose long extensions reach the skin and internal organs, are capable of regenerating after injury. This is why injuries to the central ...

A high-speed, high-resolution 3D imaging system enables whole-body mapping of the mouse peripheral nervous system (PNS) at subcellular resolution. The approach combines in situ sectioning, ...

Neuropathy is when nerve damage interferes with the functioning of the peripheral nervous system (PNS). When the cause can’t be determined, it’s called idiopathic neuropathy. The PNS carries ...

The paper, published in the journal Nature Communications, traces complex biochemical signals leading to peripheral nervous system dysfunction found in people with Down syndrome. Scientists studying ...
