jackson pollack painting. every piece here is a u little piece of the neuron. but to his trained eye, this diagram is going to help us explain why we do what we do. and this is the mesh is the entire core of the nervous system. it is a symbiotic relationship, and cardona s maps help to teach and intercept each pathway. and piece by piece across this system, we are putting together a comprehensive picture of how the brain works as a whole, which has never been p s possible before. reporter: the current map is the mapping involved in learning. we are manipulating the circuit elements and at the same time recording the outputt at the same time and the firing of
winner-take-all computation, because a nervous system cannot afford be indecisive. it cannot give confusing commands, and you cannot sit here and walk at the same time. reporter: her team teaches which neurrons kcorrelated whic which response and then reverse engineered the experiment, and activating the neurrons to perform one way or the other. we go through thousands of neurron s neurrons in this way, one neuron at a time, and ask, what happens if we activate this neuron? you would not think that a common fruit fly would be so completion, but a few years of the experiments in, they have only mapped 2/3 of the brain. everything that we do is in a very close collaboration with the lab of al carbondona and they are experts of mapping the wires. these maps look like a
response. these recordings are helping them to map the galaxy of neurons that produce behavior. it is the first step of understanding how the nervous systems work across the animal kingdom. i have always been fascinated by behavior and by the way in which the nervous system works. how can neural circuits generate, well sh, everything t we are, our personalities, our decisions, our thoughts and our ability to be creative. it is believed thathe adult brain contains sol 86 billion neurons, and at birth many of the neurons are not fully connected to each other. as we are growing and learning new skills, new neural pathways are created in our brains. it is estimated that one neuron may connect with thousands of oother neurons and the connections allow things like walking and typing and reading and other things to become second nature. each of these have a pattern or computation made up of specific
w winner-take-all computation, because a nervous system cannot afford be indecisive and it cannot give confusing commands and you cannot try to the both sit here and walk at the same time. the team discovered which neurons correlated with which response and then engineered the experiment and enacting the neurons to perform one way or another. we go through thousands of neurrons in this way, and one at ime and ask, what happens if we activate this neuron? you would not think that a common fruit fly would be so complex, but a few years of experiment experiments in, and they still only mapped two-thirds of the brain. everything that we do is in a very close collaboration with the lab of the experts in mapping the wiring die grabs,
again. ambassador haley very strong today. she said the u.s. would seek an emergency session at the u.n. to express support of the people there in neuron. that s a position supported by the trump white house. bret: warns with the panel. what do you think? do you think the president s pressure on iran lead to change and should it? let me know on twitter @bretbaier. use the hashtag #specialreport or on facebook at facebook.com/bretbaiersr. senator orrin hatch, longest-serving republican in the senate and former boxer is throwing in the towel. every good fighter nose went to hang up the gloves. for me, that time is soon approaching. that s why, after much prayer and discussion with family and friends, decided to retire at the end of this term. bret: the announcement from 83-year-old hatch, seven term senator from utah, could set up a run by very familiar face, one president trump has seemingly wanted to give out of
