All activity in the brain is driven by other activity in the brain, in a vastly complex, interconnected network.

Who we can be begins with our molecular blueprints - a series of alien codes penned in invisibly small strings of acids - well before we have anything to do with it. We are a product of our inaccessible, microscopic history.

Just like a good drama, the human brain runs on conflict.

It turns out your conscious mind - the part you think of as you - is really the smallest part of what’s happening in your brain, and usually the last one in line to find out any information.

This is the hallmark of a robust biological system: political parties can perish in a tragic accident and the society will still run, sometimes with little more than a hiccup to the system. It may be that for every strange clinical case in which brain damage leads to a bizarre change in behavior or perception, there are hundreds of cases in which parts of the brain are damaged with no detectable clinical sign.

Vision is more than looking.

Who you are depends on the sum total of your neurobiology.
