A Quote by Sam Kean
A long iron rod rocketed straight through the very forefront of Phineas Gage's brain. It's kind of an unusual part of the brain: you can suffer pretty severe injuries to it and often walk away from the injury. It's not a part of the brain that's necessarily vital for your biological self. But it is very important for personality.

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).
You love the person for who they are, flaws and all. You can't help who you love, either. It comes from a different side of your brain than the logic part that tells you that this person is horrible for you - "You should walk away!" While you're walking away, the other part of your brain is trying to gain control of your bodily functions. "Turn around! She's the one!"
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.
It turns out that this part of the brain is one of the first areas that's attacked by Alzheimer's disease. So we can now use some of the basic understanding of this part of the brain to ask the simple question, 'What is going wrong with these special cells in the hippocampus at the very earliest stages?'
I think we've reached that point where we understand medically what we are doing to ourselves with these sports. In football, it's kind of hard to get the access that you want for the story and, of course, it's very long-term: the effects of the repeat concussions really don't hit until decades afterwards, whereas the traumatic injuries in extreme sports are very immediate. I realized Traumatic Brain Injury was a fascinating and important story that not had been told very much. I wanted to know more.
A scary dream makes your heart beat faster. Why doesn't the part of your brain that controls your heartbeat realize that another part of your brain is making the whole thing up? Don't these people communicate?
It's not just professional athletes and soldiers who are at risk from traumatic brain injury. More than 1.7 million people a year sustain a traumatic brain injury, and about 50,000 of them die each year, according the Centers for Disease Control. There are both emotional and financial costs from these injuries.
As many know, brain injury comes in many forms. The two most prevalent brain injuries - stroke and trauma - affect more than 2.2 million Americans, and these numbers are expected to grow.
Everyone uses the brain at every moment, but we use it unconsciously. We let it run in the background without realizing the power we have to reshape the brain. When you begin to exercise your power, the everyday brain, which we call the baseline brain, starts to move in the direction of super brain.
The amygdala is like a point guard in the emotional part of your middle brain. When it is overwhelmed, it hijacks you away from being able to access your upper rational brain and think and assess what to do. It essentially disables your ability to think.
In the field of consciousness research-and also in physics and astronomy-we are breaking past the cause-and-effect, mechanistic way of interpreting things. In the biological sciences, there is a vitalism coming in that goes much further toward positing a common universal consciousness of which our brain is simply an organ. Consciousness does not come from the brain. The brain is an organ of consciousness. It focuses consciousness and pulls it in and directs it through a time and space field. But the antecedent of that is the universal consciousness of which we are all just a part.
All we can do now is try to prevent secondary damage by relieving pressure on the brain caused by the initial injury. There is no reparative treatment for traumatic brain injury.
Because we do not understand the brain very well we are constantly tempted to use the latest technology as a model for trying to understand it. In my childhood we were always assured that the brain was a telephone switchboard...Sherrington, the great British neuroscientist, thought the brain worked like a telegraph system. Freud often compared the brain to hydraulic and electromagnetic systems. Leibniz compared it to a mill...At present, obviously, the metaphor is the digital computer.
Just as an informal, nonscientific observation, most people's personalities don't seem to change very much during their lives. There are exceptions in the case of people who go through hugely traumatic events or suffer from brain injury or disease. Some would argue that religious conversions can have deep personality-altering effects. But these are all exceptions to the rule.
The hallmark of addiction is that it changes your brain chemistry. It actually affects that part of your brain that's responsible for judgment.
Since functional brain imaging first emerged, we have learned that there aren't very many brain regions uniquely responsible for specific tasks; most complex tasks engage many if not all of the brain's major networks. So it is fairly hard to make general psychological inferences just from brain data.
