In terms of plasticity and all this stuff is what the brain   Energy Complex  really wants to do is also pass as much of what it does off to reflexive behavior as possible So when we're talking about focus I think it can get a little bit vague but it might be useful to think about like what exactly is focus and what triggers plasticity? So the brain loves to be able to just do things pick up coffee cups and drink and walk and talk and do things and not put much energy into it When we decide to focus what the brain really does is it switches on a set of circuits then.
