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.

The results of a study conducted in Brazil suggest that the sympathetic nervous system - the part of the autonomous nervous system that controls responses to danger or stress - can modulate the action ...

Rutgers Robert Wood Johnson Medical School and collaborating institutions have found that overnutrition leads to insulin resistance and metabolic disorders through increased activity of the ...
