all of the swelling and my cortex was completely dysfunctional. that is why i was behaving in some aspect like a mentally ill person and i didn't realize it because i needed my frontal cortex, so the part just behind the 4 head to understand i was missing one, but mine was not functional and i couldn't believe it was a catch 22 situation. i was treated with high doses of steroids to reduce inflammation and targeted therapies. my doctor agrees with me in my altered state that immunotherapy helped me, a strong response that i might lose it if we don't go to the hospital and swelling wasn't reduced, my brain would stop working altogether, i would not be able to breathe or function at all. so over the next few months, i was going back to reality and it was a small process. it was as if through my broken brain the light started getting in very slowly. i remembered some of the time, many i did not remember but what i didn't remember mostly was emotion associated with the facts so i could remember i was walking with my son but didn't know what he was thi

one is bleeding in the visual cortex. the bleeding strongly suggests that it is melanoma. so that is melanoma that i had on my neck spread to my brain. so what did we do? i couldn't go to montana, unfortunately. i cancelled the trip. went to boston instead to do surgery, radiation, and we knew that all of us knew that i basically got a death sentence. there's not much to do if you have brain tumors, melanoma brain tumors or breast cancer brain tumor. same thing. either extremely hard to survive it or rather people do not survive it. melanoma in the brain at the time was predicted to give me four to seven months to live, and i was prepared for this. i actually was absolutely sure i will die. i was even more sure because in my life, it already happened. my first husband died of melanoma in his brain. so i had already this experience, and it was pretty terrifying. so we go to boston instead of montana, and we check out into the hospital and i have surgery, and then what? we have to enroll in something very new and hopefully something that will have a potential, at least to sa

in severe epileptic cases half of the cerebral cortex is removed and children are actually still able to live their lives. of course they are paralyzed from the opposite side. many of you know that this site controls the side but these are children that cognitively our normal and that have a sense of humor. there was a group of these kids who are operated on at johns hopkins and doctors there wrote about their experiences and were just amazed by the normalcy of these kids that grew up with this very severe deficit in the number of neurons and the size of the brain and so on. .. >> are not the organisms like whales or elephants imagine that scale but we think we are smarter but they have big long -- bigger brains but what i want to point out that is looking at a bunch of rodents. and it is about as big as a pig or large dog it is called a pygmy mouse and the brain 50 times smaller than a capybara. but these animals are part of the same family in the animal kingdom and operate in the similar ways in terms of behavior this all similar tasks in nature it's hard to give them the iq test.

there are a lot of the cortex that really concentrate on the quartet repertoire you guys decided you had to be something different i think we we might be different i'm not sure if we decided. to get going you know i think it's just a reflection of all of our interests because we like somebody things and and we want to kind of experience the world through the string quartet and it turns out to be a vehicle where you really can do that very easily because. you know our tradition really is a world. that i think. of us having technical boundaries that there are any crazy pieces where you sit on the i'm not doing enough for you because i know violins are quite expensive things and at the rehearsal yesterday you were getting some incredible sounds out there isn't that is there anything is there other than the boundaries or do you guys still i think you know we are we always get you know asked to do things that you know we haven't done before it's definitely part of the tradition right do you think about leaving les peterson string quartets people so they were unplayable at the time people

the pituitary releases this thing called another hormone that acts on the adrenal cortex that interimreleases a hormone called cortisone. you probably heard of it and it's part of what sort of induces our bodies stress response to does what it is most famous for. in laboratory studies we often measure the cortisol levels in the blood as the kind of surrogate for whether an animal distress because they can't tell you. i'm stressed. we just measure their cortisol and that knows better. anyway, so cortisol exerts all kinds of body wide activities. it's part of what makes you breathe faster, your heart pumps faster. it dilates your blood vessels. it makes you flush. this all looks superficially like a top-down regulation system. because i said it starts out here in the hypothalamus in the brain and goes down to this other place and you get a fix. looks like at that than kindle ms. mcsally put that arrow back in. that's because when you are a body into the brink, your brain is attuned to things that are going on in your body, that your body actually influences what's called interception. y

initially an action requires our full concentration which takes place in the brain's prefrontal cortex its cognitive control center. but once an action has been performed over and over we get stored in deeper brain regions associated with automatic behavior. but it's a very clever arrangement one that frees up our conscious mind for new and more important tasks. like filtering information. and making decisions. if we didn't have automatic behavior our brains would be constantly overwhelmed. thanks to routine though we can switch to autopilot so to speak and just get on with our day. so without the need to pay too much attention to basic repetitive tasks we can concentrate on more important things allowing us to perform complicated tasks correctly and safely. ten of mt put trade in walt disney's famous animated film the jungle book is not just the stuff of stories again and again there have been reports of children actually raised by wolves or dogs. and in fact human and wolf social structures have a number of things in common both live in family units for example but wild dogs are ofte

during deep sleep phases slow brain waves a rise in the cerebral cortex and propagate to the hippocampus an interim storage space for information absorbed during the day. in deep sleep the positive wave patterns reactivate the information during this process it's transferred to the long term memory where it's stored in a more permanent form acoustic stimulation reinforces the slow brain waves. that encourages deep. sleep and the subsequent formation of long term memories this is certainly conceivable that devices like these could be developed for daily use in the near future and you can imagine a scenario where the sleepers may be wearing an amplifier on a band around their forehead that's able to detect slow oscillations of doctors and that would then be linked for example to a smartphone which would play the right acoustic signals to the sleeper at the right times. for through. with their successful study the researchers have opened the door to new methods of influencing memory and the quality of sleep. this week our viewer's question takes us under the sea there's a whole world there

the left side of the cerebral cortex. stalls general knowledge including speech. here. even though peter hails from england he can communicate easily with anna who learned english in school. what's called perceptual memory is located in the cerebral it helps you recognize patterns. allowing anna to identify an apple as an apple. and letting pizza pick anna's face out of the crowd. the more you exercise your brain the better you can recall memories. that's why peter has dedicated himself to rehearsing this song but his singing group. is good . but what really sticks in the memory of powerful emotional moments because peta tries so hard to please her and i remember every new dish he's ever cooked. the birth of their first baby is another experience peter and i will no doubt always remember but what if they never have children studies show that spend counts are falling dramatically among men in the west and won't it's an alarming trend with potentially catastrophic consequences. are humans a threatened species. for now our cities are densely populated but the western indus

in my brain the control room where the boss sits so to speak is the pre-frontal cortex it's where i decide yes it's worth getting motivated or pass. the boss has upped the ante the raise has been raised from twenty to fifty euro's we might be approaching the threshold where motivation kicks in yes this is starting to sound more attractive let's go for it. a reward is in the offing my brain is starting to release chemicals i'm high on dope i mean like sugar for the brain. mind you clear circumvents only comes to life when the motivation is great enough so it thinks the reward is worth it now. i'm all revved up in case you hadn't noticed workers are not machines they have feelings and emotions which are generated in the limbic system it's those emotions that spur us on but we need for riot to keep us satisfied. the same thing over and over will not do. we have individuals after all and each of us is motivated by different things. so boss you need to find out what flies my kite it will begin your own interest. the message through manages but how does it really work in the corporate sector pay

modern jazz cortex. chip by coal these people they all wore ivy league it's not just poor well of the musicians suggs from madness to turn band is on and he says he kind of brushes it off quite quickly that skinheads obviously adopted the hiring joe that it was associated with he was a little bit about some of the right wing politics and the race itself do you think where they came with us you know well the scary and we didn't get skinheads we had what you call suede heads which were sophisticated skinheads and they were less racist whether they were just i wouldn't. want to say that but it was modified but but gradually that element did come out of it and. the west indian guys come in where in outlook and they were really happy in the shop they come along on a saturday and they say i want to parody blockbusters they're big heavy shoes you're used to so a parody that was a nickname from the blockbusters what size are you going to go no i got take that. take that you know i don't seem to have many to imes

and can pass through tissue more easily, so they can target just 4% of the brain, in the prefrontal cortexin areas affected by depression. >> lisanby: okay, so this is the magnetic coil. >> cooper: dr. lisanby showed us how the magnetic coil can pinpoint a specific area of the brain. >> cooper: so what is on the monitor? >> lisanby: okay, so on the monitor, we're looking at a brain scan showing us-- in real time as we move the coil around on your head-- it's showing us where on the brain surface we're targeting. >> cooper: so, so this allows, allows it to be more precise, in terms of where you're stimulating the brain, as opposed to e.c.t., which would have a larger area of the brain. >> lisanby: that's right. we can focus the magnetic field more precisely than we can with e.c.t. for example, we can even find just the right spot in your brain to make your thumb twitch, but not the rest of your arm. >> cooper: okay. >> lisanby: so, shall we try it? okay, so i'm going to go ahead and put the coil on your head, and you're going to hear a clicking noise and feel a tapping on your head. are you

so it's the utter misuse and the ultimate misuse of the prefrontal cortex. but we all do it.nd trump does it in extremus. >> and again, to me, if somebody on the staff apologizes, he views that person as weak? >> not only that he'd view them as weak, and everyone in trump's mind is either weak or strong, is either rich or poor, is either tough or wimpy. but it's also that that person is always reflecting on him, because the only person trump sees at any given moment truly is himself. so everybody is a reflection of him for better or for worse. in this case, if there were to be an apology, it would be for worse. >> tony schwartz, fascinating. thanks very much. appreciate it. >> thank you. >>> coming up, president trump today at a memorial for fallen officers talked about a border patrol agent who died in the line of duty. some republicans have been saying that he was attacked. we'll have the latest on what investigators now believe happened. >>> also the new reason why meghan markle's father will reportedly miss the royal wedding. it has nothing to do with some paparazzi photo
