Grey Matter in the Cortex is far more complex than the hard wired ganglia at the base of the brain...
So Grey Matter liberals may be more flexible and prone to risk taking and experimentation and creativity....
The base of the brain has been fixed for millions of years...its hard to effect it with drugs or therapy...
Republicans are clearly more prone to "protect their eggs"...at all costs...
....which is a very Reptilian Basal Brain response to the environment...
