The narrator’s mother turns the advanced old age of 89 years in the third part. In one incident, she wakes up, turns on a flashlight, and enters the room. She whispers to her granddaughter Yoshiko, that “she can’t go out anymore.” She thinks she is confined to the room. Immediately after she has had her breakfast, she assumes evening has come. The family is also pulled into her increasing wandering episodes. Her dementia becomes very serious and the life of her family is brought to the brink of collapse.
The neuron nerve fibers in the brains of patients with dementia atrophy and the information cannot be transferred smoothly. In time, the neurons of the receptors will be damaged and information cannot be adequately communicated. The dietary intake of acetylcholine essentially becomes insufficient and communication areas and other symptoms of the disease manifest themselves. The type of dementia suffered by the author/narrator’s mother is Alzheimer’s disease. This is the most common form of dementia and the memory defects of not being able to remember experiences is often accompanied by abnormal behavior.
If the output of the reading brain “dementia and adaptive ability” is put together with “memory and balance of association cortex” seen as the writing brain, the resulting synergic metaphor would come into effect. I will consider how to balance the brain as in the section that follows.
The balance of the brain is portrayed in various colors like the writing style and the idea of life and work also becomes training. The steering of neuron networks to combine the association cortex is dealt with by the frontal cortex. If I could find the general brain activity near the balance of the brain of Yasushi Inoue, I can assume a synergic metaphor such as “Yasushi Inoue and balance of association cortex.”
