Abstract
1. The effect of tongue movement on the chorda tympani nerve responses of cat to taste stimuli was studied.
2. An increase of varying degrees in the taste response associated with tongue movement was observed during stimulation of the tongue by HCl, water, NaCl, saccharin and quinine. The enhancement in the response to HCl and water was found most remarkable.
3. With a given taste stimulus, magnitude of the augmented taste response was found to depend both on the time after the initial maximum of the taste response and on the sensitivity of the receptors to taste stimuli.
4. The rate of adaptation in the taste response was prolonged as a result of the enhancement in taste response.
