Most of the crystal brains were divided into two halves, one left and the other right, like human brains. Looking through the transparent crystals, one could vaguely observe the structure of the brain, such as the brain margin and the brain stem.
Since it was carved out of crystal and emitting glamorous colors, although the details such as the cerebrospinal canal were vivid, it did not give the feeling of disgust or evilness. Instead, it was filled with the holiness of thinking.
As for the other crystal brains, not only were they much larger than normal human brains, they were also in various forms.
Some brains were made of three different parts connected by thick clusters of crystals.
Some brains were like abnormal tumors with irregular bumps on the surface.
Some of the brains did not have ditches at all. Instead, they were full of dense holes that looked like delicate honeycombs.
