Control that darkly wandering mind

Dragons of Eden by Dr Carl Sagan does talk about some

Pre historic lizard brain neo-cortex : i'm confused about your lizard core brain whether it's the same concept as Dr. Sagan was pushin' ?

Okay, my scientific lady

The first part was scary but great message. I don't think I like things cascading through my axons - do I?

The lizard brain...the Amygdala‎...the same one we share with lizards...this part of the brain was the first to develop. Evolution spent many years building brain structures to control those base urges.

You love things cascading through your neurons, that's the problem...these chemicals are like a drug, you feel them and you need more. Brains evolved to reward these chemicals of fear because you're more likely to survive if you fear.

Okay, fine, if you say so

But it still sounds like something we good kids avoided in the sixties...
