| Research Abstract |
It is known that taste can act as a conditioned stimulus (CS) for conditioned food aversion. In the present study, in order to examine whether or not the temperature and hardness of foods can be a CS, we conducted behavioral and neuroscientific experiments in Wistar rats. The results were follows : (1)The rats subjected to aversive conditioning to temperature of distilled water could learn to avoid these CSs, but they did not avoid any taste stimuli. (2)The rats subjected to aversive conditioning to hardness of foods also could learn to avoid these CSs. (3)The rats with bilateral lesions of amygdala could not acquire conditioning to temperature and hardness of the CS. (4)When the rats subjected to aversive conditioning to temperature of distilled water durunk CS,FOS proteins were expressed in their amygdala. These results suggest that rats can be conditioned to temperature and hardness of foods aversion and that amygdala plays an important role for this conditioning.
