mdma reduced actively in the amygdala where fear is processed and it increases activity in the frontal cortex where people put things in association, in context. so people are able to look at traumatic memories, the fear is reduced, and then they're able to separate out it was happening then and not now. and then they don't have to be triggered so much when they have the memories. >> so if they're going through counseling, for example, it could make that counseling more effective, they're not as paralyzed if you will by the memories that are being brought up? >> yeah, we're saying that mdma itself is not the medicine, it's mdma assisted psychotherapy. >> there is other research, historical research, including some of it done in the army as we saw there in the clip we just watched, some of it's crazy to watch, some of that footage, it looks nuts. but did we learn something from that we're now applying? >> oh, absolutely. from the time that albert hoffman discovered lsd and started sending it around to labs around the world, it became the most studied psychoactive drugs in history. and it was c

then finally when you become an adult by the frontal cortex at the front of the brain develops. so we can now test old wives tales by looking at the living brain. what old wives tales has that their teenage kid suffers from brain damage. it's true. you can show as it develops on the back to the front, teenagers do not have a well formed for tax. it's another old wives tale when a man talks to a pretty girl he starts to act stupid. [laughter] it's true. when a man talks to a pretty girl, blood literally drains from the cortex and he becomes mentally retarded. [laughter] you can measure this but it's absolutely true. all of these old wives tales cannot be systematically analyzed looking at the scans. then we have two hemispheres. the one on the left and the one on the right. normally the hemispheres talk to each other but in epileptic get out of control and have seizures so they have to cut the connection between the left and the right. the two brains that are now cut begin to create two different personality. it's amazing and documented cases one man comes home and greets his wif

let's go back to the cave person tending to the fire is using this part of the head of the pre- frontal cortex it's the thing that makes us most human and we are responsible for architecture, civilization. but essentially signal up from here the reptile parts of the brain are much more permanent survival mechanisms and in the case of the lion it says to lie and run. in this part of its kind during the high-level task must listen to that lower part of the brain because if it isn't, guess what, you get eaten. so now let's go back in time to start to understand these limitations of our brains. we cannot ignore, first of all, that reptile sound. i mean come if you can view it is actually have to have eyes in the back of your head. so, going back to probably the mid-19 hundreds by after world war ii, scientists in britain were wrestling with the question of why was it that the pilots in airplanes fighting the battle over britain why was it the radar operator could have trouble with these screens and cockpits and with what they were looking at? why was was it they couldn't focus on a life and death

i shouldn't be driving in the snow in the dark and the dave predator priests frontal cortex isn't fullyformed it lacks the message to fend off that reptilian signal even more. they are at the most risk and susceptibility. >> host: which is a very powerful, very very powerful problem in society right now. let's talk a little bit again about the wider sociological trends. you mentioned the messages that we are getting. multitasking is great and you can do it anywhere and this is the picture of success etc. but let's talk a little bit more about those messages. it has everything to do with how we see technology and what technology gives us. >> guest: how to find us and there's a matisse mode associated with it. on a practical level there's a study in the book that shows especially on people but it would be true of all of us the value of the text falls sharply literally with each minute that passes. it makes common sense so let's say you're the team or the employee or whoever driving in a text comes in and the text is party at jane's house in 15 minutes and you don't look. he missed the par
