#Fokus nzt mood enhancer driver
The eyes are fundamentally the most powerful driver of what we think, what we feel, and ultimately what we can do, because they set the basic level of alertness or sleepiness. Just like at a factory, not all the cells are going to do the same things at the same times, but they need to know when to do what they need to do. And so the eyes are responsible for instructing the brain, and then the brain is responsible for instructing all of the cells of the rest of the body, when to do their respective jobs. That’s a 24 hour rhythm or very close to it, so called circadian rhythm. If you take out a cell from your liver and put it in a dish, it will have a rhythm in activity, a rhythm in metabolism. And so, every cell in our body has that 24 hour clock. We’re a diurnal species, we’re not a nocturnal species. How does your brain know when to be awake or when to be asleep? Well, it knows, based on when the sun is out or when the sun is down. Eyes were designed, first and foremost, to set the overall arousal state, the alertness or the sleepiness of the rest of the nervous system. But that’s actually a late stage evolution of what eyes were designed for. We think of the eyes as for seeing, for seeing objects, where they move, et cetera. I thought it was a cool project so that’s what I did for my senior thesis. I’d never been to a rave, I’d never done MDMA.
And back then there was a big rave culture. Actually, my senior project was looking at how MDMA, ecstasy, leads to shifts in body temperature. I was really interested in the biology of addiction. But I took a course that got me really excited about thermal regulation, how we regulate body temperature, as well as addiction. What we now call neuroscience was fractured into neurochemistry and neuro genetics and psychology and bio-psychology, and now it’s this unified naming thing we call neuroscience. I went off to college, I took a class in bio-psychology because back then there wasn’t a field called neuroscience. And why do some people go down the path of depression and suicide, violence, and others just focus on their sport or their craft? It was clear to me in those years that people were showing up with different genetic makeups, different propensities for success. Questions about, why do some kids take a sip of alcohol and become alcoholics? Whereas I didn’t feel that. I had all these questions that eventually I took to my scientific career. “The eyes are fundamentally the most powerful driver of what we think, what we feel, and ultimately what we can do, because they set the basic level of alertness or sleepiness.” In This Episode:
In this conversation we discuss the influence of vision and respiration on human performance and brain states such as fear and courage. He is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award in 2017, which is given to the scientist making the largest discoveries in the study of vision.Īndrew is also actively involved in developing tools now in use by elite military in the US and Canada, athletes, and technology industries for optimizing performance in high stress environments, enhancing neural plasticity, mitigating stress, and optimizing sleep. He has made numerous important contributions to the fields of brain development, brain function and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills and cognitive functioning.
