    Abstract

    Context

    Wisdom is a unique psychological trait noted since antiquity, long discussed in humanities disciplines, recently operationalized by psychology and sociology researchers, but largely unexamined in psychiatry or biology.

    Objective

    We discuss recent neurobiological studies related to subcomponents of wisdom identified from several published definitions/descriptions of wisdom by clinical investigators in the field – i.e., prosocial attitudes/behaviors, social decision-making/pragmatic knowledge of life, emotional homeostasis, reflection/self-understanding, value relativism/tolerance, and acknowledgement of and dealing effectively with uncertainty.

    Design

    Literature overview focusing primarily on neuroimaging/brain localization and secondarily on neurotransmitters, including their genetic determ

    List of Nobel laureates

    The Nobel Prizes (Swedish: Nobelpriset, Norwegian: Nobelprisen) are awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institutet, and the Norwegian Nobel Committee to individuals and organizations who make outstanding contributions in the fields of chemistry, physics, literature, peace, and physiology or medicine.[1] They were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. An additional prize in memory of Alfred Nobel was established in 1968 by the Sveriges Riksbank (Sweden's central bank) for outstanding contributions to the field of economics. Each recipient, a Nobelist or laureate, receives a gold medal, a diploma, and a sum of money which is decided annually by the Nobel Foundation.[2]

    Different organisations are responsible for awarding the individual prizes; the Royal Swedish Academy of S
