[CW: Medicial, Brains] Split-Brains are fascinating.

SO! Split-Brains are when for reasons the left and right hemispheres are not connected. Most common is from surgeries designed to eliminate severe seizures. Surprisingly, it actually works as intended, and unlike a lobotomy the person is generally the same

in personality, intelligence, and memory.

But the brain does a weird thing, where because the brain is split, it does not properly transmit information to each other.

So a split-brain person could in fact draw two entirely different objects at once because the data isn't being transmitted - there's nothing to force the hands to focus on one thing.

And there's the HE ART experiment, where the word HE ART is put up, with HE on the left side of the eye (where it transmit to the right hemisphere), and ART to the right part (it transmit to the left). When asked to tell what word they saw, the split-brain only sees ART.

But when asked to point out the word, the left hand points to HE

confusing the subjects.

Or if they flash a picture of a spoon to just the right hemisphere, the patient is unaware of it, but if asked to feel objects for what the scientist is asking for, the left hand again automatically selects a spoon.

I've read about this, it is utterly fascinating and a bit spooky too

Brains are weird!

Hasn't there been evidence of the two halves of the brain having their own preferences for different things with this condition? Am I recalling that correctly?

But man yeah brains are SO weird and complex and there's still so much we don't know about them

yeah, there's some mention of it in the text book.
