The reptilian brain controls much more of our behavior than we realize. Use the power of the reptilian brain to optimize your counseling. "The reptilian-lizard brain is an ancient beast. It was developed over 100 million years ago. The higher brain or the neocortex came along a mere 40,000 years ago. So, when the reptilian brain is on alert, it's pretty hard for a youngster like our neocortex to tell a 100 million year old brain to behave!2"
