| Research Abstract |
In fetus, young, developing and adult stages, effects of stress on the taste sensation were investigated behaviorally in the rat. Relative sensitive basic tastants against stress were sweet and bitter. Sensation of somatosensory irritant (Capsaicin) was also modulated by stress. In addition, stress effects were different among life stages and between sex. Naloxone affected modulatory effects of the stress on the Capsaicin sensation, suggesting that endogenous opioid system is involved in the mechanisms of stress-induced modulation of irritant sensation.
