though she had a type of lump in her esophagus that felt like she couldn’t swallow. She received drug therapy, and as much as it helped, she still suffered from minor panic attacks. Soon after she was off the drug therapy, she went into rehabilitation that taught her brain how to resist the attacks. This helped her greatly, but she still had the same stressful job and she was still surrounded by stressful situations. She was also suffering from exacezbated anxiety. This type of anxiety is felt by everyone at all the time, just some of us have it in a more profound level. People that suffer from this consider everything they do in life to be extremely stressful, they try to avoid most things in life. Valium is most often prescribed for this anxiety, and it does a great job in

curing it. Anna also developed a few phobia’s, or fears of things. She was afraid to ride the metro or afraid to be in a large crowd. Her panic attacks have greatly shortened, now they last a minuscule one to two minutes. Her first day off of any medications was a bit shaky. She has just learned new techniques to try to conquer the attacks, and she has also returned to work. She now has stayed drug free, and her chances are constantly improving because of the fact that she does vigorous exercises in order to get rid of unnecessary stress. Different types of things you may also do to get rid of stress are yoga, faith, and even prayer. Our understanding of the changes that occur in our brain has improved immensely. All advances do have the possibility to be misused in a

controlled way, but the positive outcomes out weight the negative ones. As for the air traffic controller, his wife had another child. This is another stressful situation that must be dealt with care. During labor, she was given a spinal tap so that she wouldn’t feel any pain what so ever, but there was a problem. She had too much stress, her blood pressure rose, she felt bad altogether, too many messages were getting sent from the limbic system to the frontal cortex. After a few minutes of this, equilibrium was restored, and her vital signs returned to normal. There was a minor problem with the delivery, and the child had to be surgically removed, but it came out in perfect health. So the question remains “Do we have the knowledge to control all parts of life?” All we

really have to remember is that behavior is a simple part of our brains’ function, and we will have to find the rest out later. “Learning and Memory” We are just now beginning to understand exactly how the brain works in respect to the way we memorize things. There are two basic approaches that we have developed to learn about the way memory works: 1) we view neurons through microscopes and then try to determine the way they function; 2) we look at other human beings, the way they act, especially amnesiacs. We are faced with one of the many questions about memory, and that is “Where are our memories started?” Karl Lashley is a scientist that in the 1920’s preformed experiments to decided where the memories we remember are stored in our brain. He removed different

parts of the brain from different lab rats and then studied the rats to decide if the part he took out had any affect on there past memories. He trained the rats to remember a certain type of maze, and after the rat could walk through the maze without any difficulty, he surgically removed part of that rats brain. After the rat had time to recover from the operation, he put that rat inside of the same maze and tried to see if the rat’s memory was at all altered by the operation. Through his many experiments, he concluded that our memories were stored in the temporal lobe of the brain. Dr. Donald Hebb helped and also studied with Mr. Lashley. He stated that if more then one fifth of the frontal cortex is removed, that it then starts to have a negative effect on memory; but if

less then one fifth of the cortex is removed, the no real loss of memory is experienced. He disagreed with Mr. Lashley, however, because Lashley stated that memory can be localized into a certain part of the brain. Dr. Hebb stated the complete opposite, that memory cannot be localized in any real part of the brain. Dr. Hebb also proposed the idea of cell organization. Wilder Peafield, who was also accompanied by Dr. Hebb, was fascinated on how the brain actually remembered what we do. He stated that memories were stored in the temporal lobe, and he concluded experiments to support this. He had a female patient in which he operated on her temporal lobe. Before any operation, he always did stimulating exercises on the part of the brain he was going to work on so that he could
