What is the purpose of the cortex in the human body?

Deepak Chopra
Alternative & Complementary Medicine
The cortex assembles the mass of raw data (continuous signals about body's state of chemical balance, temperature, and oxygen consumption, along with a crackling stream of nerve impulses) into complex arrangements of electrical and chemical blips. The cortex doesn't inform us about this never-ending data processing, which is all that is happening inside gray matter. Instead, the cortex tells us about the world -- it allows us to perceive sights, sounds, tastes, smells, and textures -- the whole array of creation. The brain has pulled an enormous trick on us, a remarkable sleight of hand, because there is no direct connection between the body's raw data and our subjective sense of an outside world. The cortex assembles the mass of raw data from the body.
