Amplitude modulation of pulsatile insulin secretion by intrapancreatic ganglion neurons.
Neuron activity and insulin release were measured simultaneously from 33 preparations of intrapancreatic canine ganglia and pancreatic parenchyma adjacent to the ganglia. The electrical activity of single neurons of the ganglia was recorded with intracellular microelectrodes, and insulin release from the attached islets was determined with an enzyme-linked immunosorbent assay. Insulin release w...
متن کاملCarlo Simulations of catecholamine neurotransmitters using cell - attached patch amperometry
Introduction: Catecholamines are charged neurotransmitters found in the neuroendocrine cells called chromaffins. The release of catecholamine, through a narrow fusion pore of a chromaffin cell requires a charge compensation by other ions to maintain an osmotic balance of charges. The aim of this research is to show that the exocytotic catecholamine release is not associated with the cation flux...
متن کاملSpeed of Ca2+ channel modulation by neurotransmitters in rat sympathetic neurons.
We have measured the onset and recovery speed of inhibition of N-type Ca2+ channels in adult rat superior cervical ganglion neurons by somatostatin (SS), norepinephrine (NE), and oxotremorine-M (oxo-M, a muscarinic agonist), using the whole cell configuration of the patch-clamp method with 5 mM external Ca2+. With a local perfusion pipette system that changed the solution surrounding the cell w...
متن کاملAmperometric detection of stimulus - induced quantal release of catecholamines from cultured superior cervical ganglion neurons ( amperometry / sympathetic neurons / synapse formation / stimulus secretion coupling / black widow spider venom )
Amperometry has been used for real-time electrochemical detection of the quantal release of catecholamines and indolamines from secretory granules in chromaffin and mast cells. Using improved-sensitivity carbon fiber electrodes, we now report the detection of quantal catecholamine release at the surface of somas of neonatal superior cervical ganglion neurons that are studded with axon varicosit...
متن کاملModulation of activity in dorsal root ganglion neurons by sympathetic activation in nerve-injured rats.
1. Teased-fiber recordings were made from the axons of dorsal root ganglion (DRG) neurons in rats that underwent transection of the sciatic nerve 4-22 days previously. Many of the neurons had spontaneous ectopic discharge originating from within the DRG. 2. When postganglionic sympathetic efferents ending in the DRG were activated by tetanic stimulation of the T13 and L1 ventral roots (VRs), th...
