In the past 20 years, brain research has been greatly influenced by functional magnetic resonance imaging (fMRI) technology. This technique allows researchers to study brain activity while individuals are performing psychological tasks. This has allowed psychologists to gain more insight into psychological constructs and create a more comprehensive understanding of the human mind. Transcript: "How has psychology in the study of our brain changed in the past 20 years? Well, this is a really big question, but I want to start by saying, you know, we've known for a very long time that specific regions of the brain are related to specific psychological function. So for instance in the 1800's Paul broca and Carl Wernicke showed that patients who had very specific lesions and parts of the brain, show different patterns of impairment in language processing. So this type of research Has been around for a very long time, but what's changed in the last 20 years, really? The last 30 years is a technique called functional. Magnetic resonance imaging has come to dominate, human brain research. So fmri was introduced about 30 years ago and what it does is it uses a standard MRI machine but allows you to look at brain activity changes when people perform psychological tasks. So this so for instance, I could take A healthy individual and undergraduate, put them in an MRI scanner. Ask them to do something like a memory task and try to say, you know, what's going on in the brain. When they perform that memory task, this technique has exploded and it's used in Psychology. It's not the only Technique we have for studying the brain and of course, like all techniques, we have for studying the brain or psychology, there are pluses and minuses to this technique, but it makes studying the brain readily available to the point where now psychology Miss routinely have MRI machines. So there's an MRI machine here in the basement of my office building at Harvard that I can use to study the brain function of individuals while they perform psychological tasks. So, I would say, brain research has started to really influence and become an integral part of how we understand psychological function. We can still think about them as different levels of analysis. I can understand the behavior of their mental constructs. Yes. But if I can also understand the brain function, I can get more information about those psychological constructs and produce a better more, complete science."
I'm highly optimistic about entrepreneurship because of its potential to deliver better results at lower costs, as well as the global capital and purchasing markets that have been developed. This process has already proven to be transformational in places like Brazil, despite economic and political challenges. Transcript: "First of all to me entrepreneurship is like a religion. So I'm all in on the possibilities particularly in those situations. For example where you can deliver Better Health outcomes at lower cost, better educational outcomes at lower cost or supply energy with fewer externalities. So I'm highly optimistic about that process and think it's in fine form around. The world, it's been transformational. So in a place like Brazil, which is a large economy. You see people creating financial institutions, that weren't there that we all take for granted. And even in spite of all the political chaos, that we observe or some of the economic problems that place, like Brazil is having you see entrepreneurs creating and capturing customer value at a scale that is astonishing to behold. So I think in every country in the world that same process is going on and we have developed Capital markets. We have developed purchasing markets ways to get customers and so I'm really quite optimistic about that."
To get ready for a workout, warm up, have a plan of what you will do, dress appropriately, be in a comfortable environment, and make sure to have proper footwear and stay hydrated. Transcript: "Other than warming up, getting ready for a workout, you need to have a plan. You need to know what you're going to do. Obviously, you need to be dressed appropriately, and you need to be in an environment that is environmentally. It's not too hot, not too cold. And again, you're dressed appropriately, you have proper footwear, and you're properly hydrated. Other than that, there's really not a whole lot else to do to get ready for a workout other than warming up and getting your body mentally and physically prepared for more intense physical activity."
My dynamic warm-up before a workout consists of 5 minutes on an assault bike, leg swings, arm swings, and gradually increasing the load with body weight or empty bar exercises. Transcript: "My dynamic warm-up before a workout consists of five minutes on an assault bike and then I'll do some leg swings and then leg swings and arm swings and that's really about it and then whatever exercises that I start out with I usually start out with body weight or empty bar and then gradually increase the load to my to my training weight."
Start out with a goblet squat to get the feeling of a front squat, holding either a kettlebell or a dumbbell to your chest with both hands while you perform the exercise. Have somebody supervise just to make sure that you're performing the exercises correctly. Transcript: "If looking to add front squats into a routine, brand new with front squats, then again I recommend having somebody supervise just to make sure that you're performing the exercises correctly. Otherwise, I would recommend that you start out with a goblet squat, which would be holding either a kettlebell or a dumbbell to your chest with both hands while you perform the exercise. That will give you the feeling of a front squat. Similar movement, the load is on the front of your body, but it's a little bit easier to maintain the weight and handle the load rather than trying to balance the load on the front of your shoulders."
Humans share a last common ancestor with chimpanzees and bonobos, two million years ago their lines split, and humans are the closest living relatives to both. Transcript: "We actually have two closest living relatives, which are equally close related to us, the chimpanzees and the bonobos. We share a last common ancestor with them about 10 million years ago and they kind of continue this as one species from that point. And about, let's say, two million years ago, their lines split again in what we know by now today are the chimpanzees and the bonobos. And interestingly also for them, humans are their closest living relatives. People think gorillas. No. So if you ask a chimp or a bonobo who is your closest living relative besides each other, for them, it's humans."
