Cold-sensitive afferents from the abdomen.
In cats afferent impulses from splanchnic and vagus nerve preparations were studied. In each splanchnic nerve serving the stomach or the adjacent part of the duodenum, cold-sensitive afferents could be recorded. There were also numerous mechanosensitive fibers originating from stomach, intestine, mesentery and the region of blood vessels. No thermal afferents were found in the vagus nerve. The cardiovascular and respiratory myelinated afferents were insensitive to thermal stimuli.
