The amygdala. Another bit of neuroscientific information. If the pineal is, as Descartes said, the seat of the soul, then perhaps the amygdala is the entry point of hell, or the origination of the ego. *shrug* I can't claim to have read enough about it to really make a comment. But it determines how we respond to fear (as well as anger).

Learning something new every day is fun, and profitable.
