Abstract
We have presented certain electrophysiologic observations on taste sensitivity and the correlation with behavioral responses to the same stimuli. An approximate agreement between the concentration ranges for the two responses was noted for the mean response curves, especially for suprathreshold effects. Receptor function was studied under conditions that modify the physiologic state of the organism and with which pronounced changes in preference behavior have been reported. Under these circumstances no change in the gustatory response was noted. It is concluded that changes in behavior under these conditions reflect not a change in the peripheral afferent neural message but changes in its significance for central neural processes.
