I underlined some eye-catching information, in Chapter 4. First I was surprised at the idea of a heart kept alive outside of a body. A heart specifically used to scientific experimentation, but would not belong to any physical body. Experiments were conducted on the heart to make it beat faster or slower. Ultimately it became a question of chemicals vs. wave of electromagnetic signals. The two challengers had the same affect. This reminds me of the different methods doctors use when someone is in cardiac arrest or having a heart transplant. Adrenaline can be used to jumpstart a heart, as well as a deliberator; this is an example of chemical vs. waves. Also, electroconvulsion shock treatment (ECT) is similar, but it is waves used on the brain.
The concept of searching for where specific memories are located in the brain was interesting. I found it especially intriguing when scientists could actually trigger certain memories and flashbacks. Considering that color and incredible details could be catalyzed, by stimulating the brain, really amazes me. Recently, I fell and hit my head. As result, I was referred to get a catscan taken of my brain. The test showed that I have an abnormal growth inside the left side of my skull and therefore, need to get an MRI. Since discovering the (hopefully slim) possibility of a tumor or something that needs to be removed, this concept caught my attention. Yesterday I was discussing brain surgery with a friend and she was explaining that during mot brain surgeries an individual is awake, but numb. In order to check a patient’s status, during surgery, a doctor can stimulate movement by stimulating different parts of the brain. For example, by stimulating a certain part of the brain it can cause a patient’s foot to twitch. Overall, the brain is an incredible phenomenon.
