"According to the results of this experiment, when the brain operates at 3.2-3.5 times speed, it generates excessive heat, leading to overheating and oxygen deprivation. The heart rate also increases accordingly, causing some operational issues. If this continues, a large number of neurons will prematurely age and die, and if these problems are allowed to expand, it will result in catastrophic consequences."
"... Premature aging, brain strokes, memory loss, high blood pressure, or drastic personality changes, all these are possible."
This is the nature of the neuronal brain; no matter how much it's modified, it cannot break through the limits.
