Glad you brought up the Pituitary gland.

The brown part of the brain system in the picture bellow, is to me the top of the pillar coming out of the Sea of Binah in the picture I posted before.

The demons (Asuras) on one end would be Binah (Saturn often associate in history to Satan) and gods (devas) on the other sides Chokmak.

But all this is dissection , nothing like feeling it while living.
