The New Human Brain

I don't remember if the GF talked about this in previous episodes but, if they could explain how the human brain will redevelop as we breathe life into the 5d and since the solar flash is supposed to elevate us in many levels... what will happen to the brain considering its split between left and right? Will it slowly start to merge and work in more of a unison fashion and or just become one brain? Why is it split between left and right anyway? If they could talk about how different things would be if the brain was one whole instead of split and if this will change sometime along the way... that would be great! Any thoughts?

Peace & love!
