The afferent input from splanchnic nerves to the lateral reticular nucleus (LRN) was studied in anesthetized cats. The activity of neurons of the parvi- and magnocellular regions of the nucleus was recorded by means of extracellular microelectrodes. The LRN neurons were stereotaxically located and identified by their response to antidromic stimulation of(More)
The activity of olivary neurons in the caudal parts of the medial accessory olive (MAO) and dorsal accessory olive (DAO) was recorded with extracellular microelectrodes in anesthetized cats. The responses were obtained by electrical stimulation of the contralateral splanchnic nerve and mechanical stimulations of gastro-intestinal and peritoneal receptors.(More)
In anesthetized cats, the unitary activity of splanchnic sensory neurons were recorded from T9, T10 and T11 spinal ganglia by means of extracellular glass microelectrodes. Twelve neurons, generally silent, were activated by perfusion of jejuno-ileum with glucose solutions (10, 50, 100 or 200 g/l). The responses indicated that the corresponding receptors(More)
It was recently well established that the vagal intestinal glucoreceptors are involved in insulin release. In this work we demonstrate that the splanchnic glucoreceptors play a unique role in insulin release: their activation induces a decrease, like strong mechanical stimulation. The physiological meaning of this effect is not clear, it may be a(More)
