| Outline of Final Research Achievements |
Research has shown that religiosity or spirituality has salubrious effects on mental/physical health. We focused on religious beliefs and behaviors and explored their functional aspects regarding attachment and mental health among older people. In parallel, we longitudinally analyzed volumetric brain areas related to afterlife beliefs. We found inverse association between belief in gods and relational anxiety, and negative relationship between afterlife beliefs and 7-year-later volume of right striatum. Taken together, these suggest a biological substrate of beliefs in life after death based on attachment-related neuronal circuits.

| Academic Significance and Societal Importance of the Research Achievements |
来世信念は来世，霊魂等に対する様々な考えで構成される宗教的信念である．来世信念と，線条体体積あるいは人間関係不安との関連は，来世信念が愛着に使用される脳回路を利用していることを示唆している．来世信念が愛着の回路を介して健康の維持に役立つのなら，我が国の伝統的・宗教的習慣である仏壇，墓参り，あるいは先祖供養等は生物学的に意味があることを，ひいては文化や習慣を伝えていくことの重要性を科学的に補強してくれる．
