Style, Identity, Free Association, and the Brain

(1/1)

KenR:
Artists and readers demonstrate persistent styles. Previously, I have explained this phenomenon by a general model of humans' functioning. A theme-and-variations identity unique to an individual sets standards for physiological and cultural feedback loops common to many or all biologically normal humans. Identity governing feedbacks would explain how an organism maintains its unchanging inner nature while negotiating a constantly changing world. Recent brain research suggests a brain basis for such an identity in "task-induced deactivation." Some midline regions of the brain become less active when subjects perform tasks. Researchers explain the decrease as the interruption of a central, continually active brain system. To perform tasks, its energy goes to peripheral systems for particular actions. Such a central brain system fits the model of a persistent identity theme. The diversion of energy fits the activation of lower-level feedback loops directed by an identity theme.
