The ability of gustatory stimuli to modify the cardiac sympathetic and vagus nerve activities.
The effects of chemical stimulation of the oro-lingual mucosa on the heart rate and arterial blood pressure were studied together with changes in the cardiac nerve activities in the rat. Of four qualities of basic taste stimuli, only HCl and NaCl but not quinine and sucrose were effective in increasing the heart rate and blood pressure. These changes in the cardiovascular system were associated with an increase in the efferent cardiac sympathetic activity and a decrease in the vagal activity, although they were no longer appreciable after transection of the glossopharyngeal nerve.
