In “exhalation,” why had no other anatomist tried a brain dissection before the narrators attempt?

A. Because brain disection meant certain death for the specimen

Explanation: In "Exhalation" by Ted Chiang, the reason why no other anatomist had tried a brain dissection before the narrator's attempt is because brain dissection meant certain death for the specimen. The brain is extremely delicate to be studied, it has been seen that in fatal accidents when the skull is pierced the brain erupts in a cloud of gold. So the narrator decides to be the one to dissect his own brain, because any other scientist would reject even the idea of doing it.
