Differential responsiveness of RVLM sympathetic premotor neurons to hypoxia in rabbits.
To determine whether differential sympathetic nerve responses to hypoxia are explained by opposing effects of hypoxia upon sympathetic premotor neurons in the rostral ventrolateral medulla (RVLM), the cardiac sympathetic nerve and the renal sympathetic nerve were recorded in anesthetized and vagotomized rabbits. Renal sympathetic nerve was activated by the injection of sodium cyanide solution c...
متن کاملIdentification of sympathetic premotor neurons in medullary raphe regions mediating fever and other thermoregulatory functions.
Sympathetic premotor neurons directly control sympathetic preganglionic neurons (SPNs) in the intermediolateral cell column (IML) of the thoracic spinal cord, and many of these premotor neurons are localized in the medulla oblongata. The rostral ventrolateral medulla contains premotor neurons controlling the cardiovascular conditions, whereas rostral medullary raphe regions are a candidate sour...
متن کاملContribution to sympathetic vasomotor tone of tonic glutamatergic inputs to neurons in the RVLM.
The role of excitatory amino acid (EAA) receptors in the rostral ventrolateral medulla (RVLM) in maintaining resting sympathetic vasomotor tone remains unclear. It has been proposed that EAA receptors in the RVLM mediate excitatory inputs both to presympathetic neurons and to interneurons in the caudal ventrolateral medulla (CVLM), which then provide a counterbalancing inhibition of RVLM presym...
متن کاملTonic drive to sympathetic premotor neurons of rostral ventrolateral medulla from caudal pressor area neurons.
The responses of sympathetic premotor neurons in the rostral ventrolateral medulla (RVLM) to activation or inactivation of neurons in the caudal pressor area (CPA) were studied in urethan-anesthetized rats. Extracellular recordings were made from 32 barosensitive single units in the RVLM, of which 26 were antidromically activated from the cervical cord. Unilateral microinjections ofl-glutamate ...
متن کاملNeuroglial networks: Neurons and glia talk to each other
Recent results show that certain neurons and glia are connected by gap junctions, and that neurons can regulate gap-junctional communication by glia. The findings are inspiring a major reexamination of the role of glia in the regulation of neuronal integration in the central nervous system.
