A new study published in the Journal of Allergy and Clinical Immunology has traced how the sympathetic nervous system, the ...

The sympathetic nervous system, which enables the fight-or-flight response, was thought to be present only in jawed vertebrates. Analysis of a jawless vertebrate suggests that this system might be a ...

New research identifies a specific neural pathway (Pdyn+ neurons) that carries stress signals from the brain to the skin, triggering eczema flares by activating eosinophils.

The sympathetic nervous system was thought to have evolved with jawed vertebrates. But lampreys—jawless, parasitic fish that suck out the blood of their hosts—have a simple one, per recent research.

Researchers have created a digital topographical map of the cardiac sympathetic neural network, the region that controls the body's heart rate and its 'fight-or-flight' response. They hope this map ...

Oregon Health & Science University researchers have found that certain nerves that play an integral role in the body's "fight or flight" stress response can support pancreatic tumor growth. These ...

The mystery of how stress exacerbates atopic dermatitis, more commonly known as eczema, may be closer to being understood. A ...

Obstructive sleep apnea promotes whole-body inflammation and weakens the body's immune system. Read about related pathways and health consequences.

For years, researchers have known that the symptoms of Parkinson's disease (PD) result from damage to a specific region of the brain. A new study shows that the disease also causes widespread damage ...

In biology, the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous ...
