A Quote by Shelby Harris
When it comes to the reason why we have nightmares, we're still debating that. It's a new area of research, nightmares. And the way I like to think about it is, our brain - we have stress during the day and our brain needs to learn to process this stress.

There are people who have repetitive nightmares. And what happens is their brain is trying to process the stress and help their brain actually deal with what happens if this stress happens again, so their brain's preparing them to deal with it in case the stress happens again, but it's so scary that they awaken from it.
Brain cells create ideas. Stress kills brain cells. Stress is not a good idea
We are not carelessly designed creatures. Everything about us has purpose, logic and intelligence built into it, including how and why we become ill. The emotional, psychological and spiritual stresses present in our minds travel, like oxygen, to every part of our bodies. When stress settles is a particular area of the body, it is because that part of the body corresponds to the type of stress we are experiencing.
My lab looks at the ability of stress hormones to kill brain cells, and basically we are trying to understand on a molecular level how a neuron dies after a stroke, a seizure, Alzheimer's, brain aging, and what these stress hormones do to make it worse.
There are no genes or areas in the brain devoted uniquely to reading. Rather, our ability to read represents our brain's protean capacity to learn something outside our repertoire by creating new circuits that connect existing circuits in a different way.
I went to an arts school as a kid. We had to take dance every other day, along with drama, music and visual arts. However, wearing black tights was something I dreaded... and still have nightmares about it to this day. I think I was a pretty good dancer. I suppose that training helped me land parts in musicals... or has just given me nightmares!
There's a lot of research that indicates the brain rewards us for multi-tasking by giving us a shot of neurochemicals whenever we start a new task. Our brain rewards us even as our performance in every task degrades. We don't even notice that our performance is bad. We don't care. We feel like masters of the universe because our brain is chemically rewarding us for multi-tasking.
There is a lot of new research about how stress hormones affect your body and how you can work on giving your body as much of the good hormones as possible, because that heals your body. I am quite a rational person - so when someone could show me that there was a rational way of seeing fear in terms of stress hormones, it was easier for me to understand. I think all autoimmune diseases are very sensitive to stress. It is typical that the flares come after a period of emotional stress. The connection is quite clear.
It would be ill-advised to compare war and a sport, but I don't think the brain knows the difference. With post-traumatic stress and traumatic brain injuries in blasts with veterans, we see a very similar and somewhat unique issue with repetitive brain injuries in football.
The pace at which science has progressed has been too fast for human behaviour to adapt to it. As I said we are still apes. A part of our brain is still a paleo-brain and many of the reactions come from our fight or flight instinct. As long as this part of the brain can take over control the rational part of the brain (we will face these problems).
The most necessary task of civilization is to teach people how to think. It should be the primary purpose of our public schools. The mind of a child is naturally active, it develops through exercise. Give a child plenty of exercise, for body and brain. The trouble with our way of educating is that it does not give elasticity to the mind. It casts the brain into a mold. It insists that the child must accept. It does not encourage original thought or reasoning, and it lays more stress on memory than observation.
The research shows that if you meditate, the mind becomes still, and they can see the functionality and gray matter in the brain increase, the nervous system calm, the immune system improve and a reduction in stress.
Neurobiological research has shown that in people with chronic PTSD, both stress hormone secretion and areas of the brain connected to memory function, such as the hippocampus, appear to be affected, although exactly how and why remains controversial.
Because it is a 'use it or lose it' brain, when we develop a map area [in the brain], we long to keep it activated. Just as our muscles become impatient for exercise if we've been sitting all day.
We're as clever as we think we are, but we'll be a lot cleverer when we learn to use not just one brain but to pool huge numbers of brains. We're at a level technologically where we can share information and think collectively about our problems. We do it in science all the time - there's no reason why we can't do it in other endeavors.
We have to remain humble about our understanding of the brain, because even our most powerful tools remain pretty blunt instruments for decoding the brain. In fact, we still do not know how to decipher the basic language of how the brain works.
