Sympathetic and parasympathetic nervous systems of the fowl

open access: yes, 1951
A great many studies of the sympathetic nervous system of the fowl have been done. Tiedemann in 1810 exhibited his work on the sympathetic system under the title "Systems da la circulation du sang". He described in detail the anterior cervical ganglion^pointing out the existence of the cervical cord in the vertebral canal and indicating the carotid ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

The Four Pillars of Morality: On the Evolutionary Safe Bets of Right and Wrong

open access: yesJournal for the Theory of Social Behaviour, Volume 56, Issue 1, March 2026.
ABSTRACT In moral psychology, many suggestions have been given regarding the nature of morality as a personality trait and as a biological phenomenon. Discussing both historical and contemporary theories, a bottom‐up genetically influenced theoretical synthesis for morality is proposed.

Relation of Adverse Childhood Experiences to Clinical and Patient‐Reported Outcomes for Adults With Sickle Cell Disease: A Registry Study

open access: yesPediatric Blood &Cancer, Volume 73, Issue 2, February 2026.
ABSTRACT Background Adverse childhood experiences (ACEs) are stressful or traumatic events prior to age 18 that are known to have a lasting impact on individuals’ health and well‐being. There is a gap in understanding the relationship between ACEs and Other Life Stressors and health status for adults with sickle cell disease (SCD).

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

open access: yesThe Anatomical Record, Volume 309, Issue 2, Page 417-450, February 2026.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

RVLM C1 Neurons Innervate Sacral as well as Thoracolumbar Autonomic Preganglionic Neurons in the Rat

open access: yesJournal of Comparative Neurology, Volume 534, Issue 2, February 2026.
Axons expressing the adrenaline‐synthesizing enzyme, phenylethanolamine N‐methyltransferase (PNMT), project widely throughout the spinal cord. Many of these axons are from C1 neurons of the rostral ventrolateral medulla. We confirm that dense arrays of PNMT‐expressing, C1‐derived axons surround thoracolumbar sympathetic preganglionic neurons, many of ...
