processed visual. but he needed the help of electrodes to. the neuroscientist got the opportunity to carry out a test on epilepsy sufferers who had had electrodes temporarily implanted in their brains to treat that disease. one group had electrodes in their prefrontal cortex is. the prefrontal cortex is in front here traditionally it s associated with your higher cognitive functions for example how you concentrate how you retain things in memory those are the functions typically associated with this part of the brain not perception. but we suspected that the region does play a role with this filling in effect such as when you blink. to question much from. the electrodes read just a neural activity while the test subjects look at two images one after another showing lattices of dots. they have to decide whether the dots are oriented
vertically horizontally or die acne harder than it sounds as the arrangement of the dots is ambiguous. picture vertical horizontal or dark no using the green point the subject selects diagonal to the upper right. second picture. again diagonal to the upper right. most of the patients showed a kind of memory effect. the image of the lattice they saw first had a strong influence on what they said they saw in the next image in the scene between. those who chose vertical in the first picture and nearly always chose vertical in the second picture two at that moment the nerve cells in the prefrontal cortex were highly active even though the images aren t stored in this part of the brain. only one patient made decisions at random in her case
thousand times a day we should be seeing this but we don t so what s going on in our brain. wanted to find out the neuroscientist at the german primate center in putting in studies perception. that we don t notice the darkness when we blink is odd because the i actually reacts extremely quickly to change. it can perceive a black image lasting just ten milliseconds and the dark face of a blink is much longer about fifteen times longer. so we want to notice it. for this grooms and for the brain one hundred fifty milliseconds are an incredibly long time when you close your eyes during a blink the brain isn t getting any input so it fills up that gap food and gives a look of. as a result you don t notice the one hundred fifty milliseconds of darkness but what fills that gap. to find out shit sick how to watch the brain in real time as it
your brain isn t fully developmental age 25, almost ten years after pelosi wants a young person to start voting. some students don t take government glasses until their senior year of high school and we expect them to stop eating tide pods long after cast a ballot for president. i think you have to be clear i did an end both sides, which means there will be a lot of hurdles to get this change because it will take a constitutional amendment, two-thirds of the house and senate as well as three fourths of the states. beyond that, i think there is something to be said about what congressman ayanna pressley is saying. it had front of the thought of these movements, the pro-life movement, a majority of those kids out there are 16 and 17-year-olds. if you go to the enough is enough movement, the gun rights movement, a lot of folks out there are young people, same with black lives matter. on both sides of the aisle, young people really seem to be the folks moving the issues forward. sure t
professional careers. i m not really a baking advocate of going out there and tackling and putting your face and hitting helmets when your skull hasn t even hard wered yet. brian, see, eric is talking about the choice he made for his family. well, that s what a parent should be able to do. let the government make that decision or legislation make that decision? that, to me, is a grotesque error is if you do that if you want to think about you just talked about when the brain is fully developed, the brain isn t fully developed until age 25. so tell me why the brain is less important at age 14 at its development than it is 7 to 11 especially when the impacts are more severe. when people talk in those terms, they are not educated. they are not informed. going to go back to don t let legislation or government tell you when you can allow your son or daughter to be active in sports. that s why we need to make sports better and safer which we are doing at all levels. brian: merrill, you sto
