planned to have a baby, but now there was this set back. He only suffered a bump to the head, but he had damaged his hypothalamus. With that damage done, his brain couldn’t preform the necessary steps in order to secret the hormone to the pituitary gland to have the urges for sex. So they tried to fix it. Dr. Crowley was called in, he had preformed magnificent work on the 3 way system involving the hypothalamus. The doctor designed for Mitch a sort of portable hypothalamus. It was a small box that can be carried around your waste that contained a syringe with the hormone that is normally secreted by the hypothalamus. Then an injection is made into the abdomen, and at regular two hour intervals the hormone is injected. At first, Mitch couldn’t stand the thing. He felt each

injection as it went in and it was uncomfortable to carry around. But it did help. Almost right after the first injection, he had a change in his libido, and after about 5 days, he was completely used to the device. When he got home, he had the sudden urge to go and have sexual intercourse with his wife and he felt great altogether. The two main reasons for him having this done to him were these: one, he wanted to have children; and second he wanted to live like a normal male. He was happy to note that after having this happen to him, he and his wife have had a healthy baby girl, and it was all thanks to modern science. So what have we learned, well, the human brain has changed and has been enriched throughout the years of our existence. We also have learned that we carry the

baggage of animal behavior, and it affects the way we think, feel, act, and love. “Stress and Emotion” Everything that we feel in our bodies is produced by the brain. Our emotions, personality, love, and hate, they are all mediated by the brain. Since emotions do not have there own separate parts in our brain, it has been very difficult to pinpoint where emotions come from. There is only one emotion so far that we know of that we can locate where it originates from, and that’s anxiety. One of anxieties chief byproduct is nervousness. Nervousness is the imbalance between the frontal cortex and the limbic system. The way that we found this emotion in our brain was completely accidental. Phineas Gage was an intelligent, well balanced man. He was a modest and good, hard worker.

He was part of a team that laid out tracks for railroad cars. One day, as he had a fight with another worker over his girlfriend, he got into a terrible accident. A steel rod had been driven through his cheek and up his skull. He suffered damage to the part of the brain that is between the limbic system and the frontal cortex. So now, he is unable to have controlled emotions. You see, the brain is like a group of good railroad layers, everyone works together to get one thing accomplished. The limbic system passes information to the frontal cortex, and normally the two systems keep thought and emotions on an equilibrium. But after his accident, Phineas was unable to control any of his thoughts or emotions. His limbic system was free without any restrictions that the frontal cortex

might have given. The reason why he might have felt very little pain during his accident was because normally, pain is sent up the central nervous system to the brain, and Substance P is then passed through the synapses of neurons if enough pain has passed through the brain. There are endorphins that lessen pain in our bodies, they are released as soon as our brain senses any sort of pain. We can also sort of “block out” pain by thinking that something makes it better. For instance, we may think that drinking water eases pain, when in actuality it has no medical purposes what so ever. There is also a drug called morphine that blocks out the Substance P from ever reacting in our brains. Edward Williams was Phineas’ doctor when he came to town that day. After examination, Dr.

Williams had stated that he had severely severed the frontal cortex from the limbic system. The wound was so bad that the doctor was able to touch his two hands while they were inside of Phineas’ skull. This completely changed his life. After recovering, he faced many new changes altogether. His words were pathetic, he slurred when he spoke, he was wild and uncontrollable, he cried often and he also screamed intensely. Basically, he let all his feeling out at any given moment. What happened to him? Well, once the connection between the limbic system and the frontal cortex is gone, the limbic system then allows information and emotions to pass through the brain freely, and everything is basically uncensored by the frontal cortex. Beating all the odds he survived, but only
