In his fiction as well as in his autobiographical writings Rousseau advocated that his heart "transparent as crystal" (Dialogues, II) and eager for sympathetic communication with others, freed from verbal ambiguities and anticipating modern theories of empathy.
Hume needs some trick to fortify the idea of the self, because he will rely on our possession of a lively idea of the self, one that will serve as a source of vivacity, for his account of the sympathetic communication of passions.
"I retreated into a purely imaginary world," he says now, remembering the time he attempted to stop speaking, in the hope of discovering a more intuitive means of communication and a more sympathetic community.
Two mechanisms may help with this local communication: perivascular sympathetic nerves [17], which mostly influence the control of arteriolar tone, and backward communication along the endothelium, mediated by endothelial cells themselves.
We initially examined whether the brain is connected with the immune system via the two different branches of the autonomic nervous system (ANS), or whether it employs only sympathetic innervation for its communication with the spleen.
However, this can change because there likely exists a bidirectional communication between sympathetic nerve fibers and mesenchymal tissue which influences the neurotransmitter phenotype.
Two mechanisms may help with this local communication: perivascular sympathetic nerves [ 17], which mostly influence the control of arteriolar tone, and backward communication along the endothelium, mediated by endothelial cells themselves.
This paper reviews sympathetic-immune interaction, one major communication pathway, and its importance for health and disease.
In addition, DRG neurons express higher levels of Kv1.1, Kv 1.8, and Kv 3.1 than sympathetic neurons (Munns and Koltzenburg, personal communication).
The gastrointestinal tract (GIT) and the nervous system, including CNS and enteric nervous system (ENS), are involved in a two-way extrinsic communication by parasympathetic and sympathetic nerves.
We also showed that metabolites released from a low-frequency (10 Hz) electrically stimulated muscle-activated nerve endings that elicited a reflex increase in blood pressure, sympathetic activity and ventilation, in animals whose humoral communication was abolished.
