| Research Abstract |
We identified a series of odorants (fear odors) which has extremely strong activity to induce innate freezing behaviors in mice. We clarified rules of chemical structures ,which is indispensable to induce innate fear emotions. We cloned about 1000 odorant receptors, representing almost all of mouse odorant receptors in the mouse genome, to develop an expression screening system , and analyzed the binding specificity of fear odors and odorant receptors. As a result, we clarified the possibility that, in addition to the specificities of odorant receptors, chemical structures of odorants are also important to induce fear emotions. We identified a number of animal species that specifically respond to fear odors.
