[Afferent activity in the vagus and sympathetic pathways of the stomach following exposure of its wall to heat].

In alert dogs with electrodes implanted into the stomach branches of the vagus and n. splanchnicus, receptory formations able to respond to relatively fast temperature changes were found in the stomach wall. The most important feature of these thermosensitive structures involves their unadaptability. The fibers responsible for conduction of the thermal information form part of the sympathetic and parasympathetic and parasympathetic nerves. Two zones of high thermal sensitivity, cardica and pyloric those, were discovered.
