Outline of Final Research Achievements

Considering that pheromonal communication, which is known in animals, is used in psychological exchanges between individual humans, especially mother and infant who has underdeveloped verbal communication, we have studied mother-child interaction via body odour. This year, 1) we are developing a new method using Nano-suit immuno-chromatography and tried to adopt to detect oxytocin and cortisol in saliva. The direction to be applied to accuracy detection was examined. 2) We experimentally demonstrated that "a chemical substance detected in the human body functions as pheromones concerning with aggressiveness", which have hardly been demonstrated, and published an original paper.

Academic Significance and Societal Importance of the Research Achievements

本研究では「母親の羊水の匂い」と「新生児の頭の匂い」の作用を多面的に追究する一方、調香品を用いてその作用を新生児や母親にフィードパックすることで、周産期における母子の不安やストレスの解消を目指す。さらに、その作用が母子に限ることなく、より広範に働くのであれば、あらゆる世代、あらゆる働き手にもポジティブな癒しの効果をもたらし、生きがい働きがいを高めることが期待できる。
