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 ...

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 ...

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.

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.

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

The term “sympathetic nervous system overload” sounds daunting, but the root cause is pedestrian: stress. Stress is, of course, something we all experience all the time, but left unchecked, it can ...

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 ...

Late in pregnancy, the human body carefully prepares fetuses for the rigors of life outside the protection of the womb. Levels of cortisol, a stress hormone, ramp up and spike during labor.

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

'In a low-risk group of babies born full-term, the autonomic nervous system and cortical systems appear to function well regardless of whether infants were exposed to labor prior to birth,' says Sarah ...
