Abstract 書いてみた。
In this paper the author examines current problems in
understanding and conceptualizing “personalities” of the individual with DID (dissociate
identity disorder). In seeking biological correlate of these personalities, he
attempts to give a second look at the understanding of this issue. He first
delineates current theoretical ambiguity and potential problem about how we
understand the personality, by examining current international diagnostic
criteria and views proposed by leading experts on the topic. The general trend
is to not to acknowledge each personality as having independent sense of self,
but rather partial and fragmentary, which the author does not think matches
well with the clinical manifestations of individuals with DID. Then the author
proposes that each personality has its independent neurological correlate, a
neural network which is proposed with the notion of Dynamic Core by G. Edelman
and J. Tononi. Although their theory is not designed to explicate personalities
of DID, it can be applied to personalities of DID based on the superimposed
nature of these networks, which is partially exemplified by the brain functions
in the so-called split-brain experiments. The author then draws on current
understanding of mirror neuron system (Giacomo Rizzolatti, G., Vittorio Gallese, V. et
al.) which forms a basis for the understanding of how our sense of self is
formed. He proposes that potential dysfunction of mirror neuron system in a
traumatic and critical situation might explain how different personalities are
formed. The author then discussed how this neurological understanding might be
reflected on our understanding and treatment of individuals with DID.
