Quadrant 2.
Quadrant 2 is the left back part of the brain. This is this area that looks at very fine detail. It wants order and structure. Like the Quadrant 1's organ connection is to the heart, the Quadrant 2 part is connected with the cerebral, thinking part of the brain. When we're using the Quadrant 2 part, we're using our brain's computations based on known 'facts' from the past.
It's a learned brain. It's the brain that goes after content, it goes after detail, it wants to know 'WHAT'. It's the part of the brain that's always seeking the information associated with a current idea. It wants a qualification. It asks, "What is the evidence?"
