We all have a lizard brain. It is part metaphor and part science. Scientifically speaking, it is two almond-shaped amygdala located deep in our heads that form a sort of mini-brain.
This mini-brain seems to take over when we are afraid, mad, aroused, hungry or out to get someone. It is very primitive. It has served to keep us alive as a species for a long time, but our lizard brain can also work against us.
