The author lets familiar information integrate with the association areas of the frontal cortex (thoughts, planning, and decision), the temporal cortex (hearing) and the occipital lobe (eyesight) and wrote the novel from the perspective of a member of the geriatric patient’s family. Custom and familiar information are activated by the left frontal cortex, while unexperienced problems such as originality are related to the right hemisphere. The right frontal cortex is activated as a result. There is a 2ｘ2 rule to adjust the macro balance. I will resolve the problem by the use of dichotomy because the L format of the synergic metaphor consists of an ensemble.
The writing brain of Commentaries of My Mother is that of the adaptive decision-making based on the narrator’s priority to avoid the risk of the breakup of his family. The male author prefers the dependent type of adaptive decision-making and his left hemisphere is utilized to deal with language information in conjunction with the activity of the left prefrontal area, which is activated off and on. When I consider the type of memory displayed in the novel from the database, while there are many long memories described, the narrator’s decision-making is the adaptive type based on his priority. Therefore, the operative recall is related to his working memory.
