Abstract
The summated chorda tympani response to taste stimuli was recorded in rats during repeated occlusion of the blood flow to the tongue. It was then observed that the response diminished and disappeared within a few minutes after bilateral or ipsilateral occlusion of the blood supply. Intravital staining through the lingual artery showed that each half of the tongue was chiefly supplied with blood from its ipsilateral lingual artery. A close relation between the simultaneous variation of the systemic blood pressure and the taste response was also observed and is discussed here.This study was supported by grants from Swedish Medical Research Council grant No B71–14X‐2467.04 and Svenska Maltdrycksforskningsinstitutet.
