On May 27,2009, Sydney Cash had a research about whthaens in the human's head while they are in a deep sleep. According to it, neourons take breaks as a persontkesa deep sleep. It pauses to keep people frm sleeping, even if the condition is noisy. Sydney Cash, a neirlogist in Boston, and his team found out the way to study our inside and outside of our brain. Scientist use many tools for their experiment, and one of them is called the EEG. The EEG is also called as electroencephalogram. It shows us the graph that looks like sifferently shaped graphs that represents brain's activity. The height,width and closeness of this wave give scientists a idea of what is happening in person's head. Even though they use those patterns in their study, scientist didn't know what helps that wave to form. According to result of cash's study, the found a inteestinf EEG pattern that is allled k-complex. Scientists found out that k-complex shows up on an EEG when the sleeping person hears a noise or a sounf while they're sleeping. It helps scientist's study because it shows a significant change in th electrical activity in the brain. howevr, EEGs only measure electric signals. In the study, scientist found a better way to see the brain. They studied patients with epilepsy, a msdical condition that can cause by overactive neurons. The people with I had had tiny electrons implanted deeper inside their brain. Electrons areused to a study elecrical currents, and doctoer had hoped that these devices would help them identify the source of the epileptic sizures. Cash found out that those same electrodes could be used to study electrical activity deeper inside the brain. By comparing two set of the information, EEG and Electrones, the scientists thought they could better understand brain activity. They did the experiment about it, and the result came out to be positive. While the patient slept, Cash and the eam collected the data from both EEG and rom the electrodes. They found out that, the k- comple was a sign on the utside that neurons on the inside were taking break, which helps and keeps people from sleeping. They also found out that only some neurons take a break at any given time.
It was very interesting that our braincan form a wave that represents what they are doing. When the article said that the scientist doesn't really know what forms those waves, I was kind of depressed because i figured out that out medication and science techonologies are still very poor to truely understand how our body works by reading this article. But still I think the scientists are doing a good job and it's amazing that we had developed thid far. While i was about half way through the article, I wondered, how do they use the data when they don't know how it's formed? It was a interesting topic, and i was glad that the result came out to be positive. After i finished reading this, I promied myself that I would do my very best at studying this topic, about the brain, because I thought it was a pretty interesting topic.
