Physiological systems in the human body interact throughout life, exhibiting specific patterns during sleep. These networked ...

The enteric nervous system (ENS) often referred to as our "second brain" has become a hot topic in neurosciences and neuroanatomy both from a fundamental understanding of its physiology and for its ...

In the past two years we have observed 4 patients with manifestations of deranged function of the central nervous system in whom hyponatremia appeared to be related to an abnormal secretion of ...

Nov. 22, 2024 — While it's well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain ...

The peripheral nervous system is the part of the nervous system outside the brain and spinal cord. It consists of nerves that carry information between the central nervous system and the ...
