What divides the brain?

Answer 1

The meninges and cerebrospinal fluid separate the brain from the skull and provide protection and cushion for the brain. The meninges are composed of three layers which surround not only the brain but the entire central nervous system. From the topmost layer closest to the skull to the bottommost layer closest to the brain, the meninges consist of the dura mater, arachnoid and pia matter. The cerebrospinal fluid fills the region between the arachnoid and pia mater and within the skull the brain, in essence, floats within this fluid.

Answer 2

Stress Divides the brain

When we cross the stress line and enter into the stress zone our brain reacts. The highest control centre in the brain (right frontal pre-cortex) becomes overwhelmed by the level of stress we are encountering and it shuts down. When it shut's down the 2 halves of the brain become de-synchronized and we revert to 4 basic emotions; we are driven to food, operate out of fear and anger and use sex as a weapon of control and self satisfaction.
