Split-Brain?

Whether one sees the world as God's creation
Or as a secular mystery that science is on the way to figuring out,
There's no denying
The beauty and majesty of everything.
There are no seven wonders in the eyes of a child,
There are seven million.

i know, i'm posting so many youtube videos these days and no pictures whatsoever :\ but i've been catching up on my psyc100 readings lately, and this chapter on Consciousness has really made me marvel at just how intricate and mysterious the human brain is. this guy, V. Ramachandran, is honestly so cool. like, i've actually begun to love reading my psyc textbook (well, at least this chapter) because of him, haha. he's a neuroscientist known for his studies on individuals with certain neurological syndromes, including the phantom limb and the one this video is on, split-brain.

split-brain describes someone whose corpus callosum is severed. this is a part of the brain that allows our two hemispheres to communicate with each other. in these patients, it's as if the left side of their brain thinks differently than the right side - which gives us some fascinating interpretations of consciousness. for instance, when you display an image (say, a triangle) on the right visual field of a split-brain patient, they'll be able to verbally tell you what they saw. but, if you display the same image to their left visual field, they'll say they see nothing - interestingly though, when their left hand is given a pencil, they're able to draw what they "didn't see" (the triangle).

amazing right? or maybe i'm just in a nerd state right now :) hehe.
