Reply to comment by CoffeeFox in If each side of our body is controlled by the opposite brain hemisphere, how do we blink in sync? by killians1978

You just conduct brain surgery without anesthesia. Touch one part of the brain with an electrode and then query the patient, Doctor: What's that do? Patient: I smell rainbows! Do it long enough and you've mapped the brain. No biggy. The purest essence of science is to poke and shock stuff.

Either that or find people with injuries to specific parts of the brain and see what's wrong with them.

Yesss like the people with “blindsight” - a lot of people with damage to a particular area of the brain (I forgot the name of the region. I want to say occipital lobe but I don’t know for sure) were consciously blind, but their brain could “see” what they couldn’t unconsciously. We then figured out this part of the brain was like the middleman between the eyes and your conscious self, IIRC.

Absolutely crazy to me. Imagine that. You can’t see anything, but you can TELL something is there. You know how it’s moving. You know how close it is to you. You know how it makes you feel, but you dont know you’re seeing anything.

Yeah, philosophers and neuroscientists have long struggled with the problem of why consciousness exists. But an equally deep problem is why our human consciousness seems to be aware of such a small fraction of what is actually going on in our brains.

Do you really think you need root privileges, man? You can really hose up a system quick.

See also Hemineglect where someone has absolutely no concept of the left side of anything including the world around them. Refusing even to acknowledge their own left arms or legs.

Bruh what?? Continue…..

Also, keep these coming people. I’m a healthcare clinician & have never even heard of these things. Just fascinating.

Please reply to me if they do!

I don’t deal a lot with human stuff, I mainly specialise in plants, but the brain has always fascinated me.

That barrier between unconscious and conscious processes has always been so intriguing to me.

Man it's not that easy haha. That's primitive data. To really know what's going on, we try and understand the molecular and cellular processes going on which is honestly like previously said, "going down a rabbit hole"
