the ideas that our appetite are part of our lizard brain, they are deep inside the brainstem of our brains and then wrapped around that is a system which evolves to represent emotion so this is for emotion circuits are supposed to be in that the hypothesis and then controlling all of that is our highly involved neocortex which is where cognition lives or rationality lives. rationality is controlling these other parts of the brain. that's a great story and the story that is very popular. it's popular in industry and the media and everybody loves that story but the problem with the story is that your brain didn't evolve, no brain evolved with sedimentary layers in the cortex didn't evolve like icing on an already baked cake. people have known and evolutionary biology has been known for almost a century that brains did not evolve that way and they don't gray that way and not organize that way. brains are like companies, to use a phrase from the neurobiologist george streeter, as they grow they reorganize. they reorganize to become efficient. there's actually is highly debated still -- for the

the scan showed a tumor-his brainstem. braylon had surgery just yesterday.s. along with braylon's little sister and parent, the town every westhampton new jersey has embraced braylon, the deputy mayor started a go fund me page to support the family with all of the medical bills. it is called braylon's warriors. which is a fitting name, as braylon wears a superman necklace. >> because he is superman. so we have braylon's mom, jennifer here with us now, along with her sisters, jessica and jamiement and we have the westhampton's deputy mayor, abe lopez, and we have braylon's best friend, fernando. do you want to wave to the camera? there are so many, the entire town has coming it, first we mention just had surgery yesterday. give us a update. how is braylon doing this morning? >> he is good. he is stable. he is a fighter. he's had a little couple of setbacks, but progressing. and we're going to get him better. >> how is he feeling? have you had a chance? is he awake? >> essay wake, talking, a little tired. i mean, did he just go under, you know, undergo surgery

a relatively simple technique called deep brainstem relation to give up heard of this involves inserting electrodes into the brain to emit regular pulses like a pacemaker for the brain that allows some patients the parkinson's disease and some kind of epilepsy and certain kinds of dyskinesia to find relief from trimmers and some other symptoms. for amputees including no small number of veterans of our recent wars on recent advances in no electronics and robotics have led to new kinds of prosthetics with impressive functionality and control like arms and hands with fully articulated fingers. several degrees of freedom and responsiveness to electrical impulses sent to muscles and nerves. they're been advances in artificial sight and hearing as well, and for handful of patients suffering from locked in syndrome, that is patient can move just and i were just an eyelid orbit even less control over their bodies, brain computer interfaces allow even very slow and minimal communication have offered at least a partial escape from the greatest state of dependency and awake and sound mind a human b
