Douglas Fields  

I chose this activity because I am very interested in both biology and mountain climbing. The adversity that climbers overcome on the mountains intrigue me, and I enjoy reading about different mountain climbing experiences. From those books, I have learned that climbers face psychological issues afterwards, which directed my interest to the psychological impact post climb. In this article, I learned that the height of the mountain doesn’t necessarily affect the severity of brain damage, which surprised me. Many pro-climbers and even more amateurs are affected by brain damage after climbing, caused by fast descent and not being properly acclimated to hypoxia (lack of oxygen). I originally thought the pro-climbers would have more severe brain damage because they have climbed more and higher, but amateurs actually experience more brain damage because they are not used to the oxygen levels. The brain will also not heal itself, and damage from climbing will stay forever.

Podcast from NPR's program 'All Things Considered' 

I chose this activity because I have always been interested in dreams, especially my own. Sometimes, I vividly remember my dreams while other times I don’t remember a single thing. I think it is very interesting how real life potentially impacts what we think about subconsciously, and how our brains create situations while we are sleeping. This podcast explained a study done by Siclari, a researcher of Lausanne University Hospital in Switzerland. Siclari conducted a sleep study, in which an alarm woke up the subjects every 30 minutes during their sleep. She found that there is a region in the back of the brain that tends to be more active than other regions when we are dreaming. Brain activity patterns in this region also shows whether the dream included a face. I originally thought that the whole brain was working when dreams occurred, and it is very interesting that different parts recognize different things and can work by themselves.

In this documentary, 3 experienced climbers team up to face Meru; a mountain that has not been scaled before. Each climber had his own background, and faced different challenges along the way. For example, one climber dealt with a bad skiing accident, and a huge obstacle he had to overcome was the PTSD from that event, and strengthening to be able to climb again. This interested me because it was a real life account of what happens on slopes even more dangerous than Everest, and how the climbers take life or death risks. Before watching this documentary, I had an idea of some of the challenges climbers face on the mountains, but had no idea how intense it is. There were parts where the climbers were stuck in a tent strapped to the side of the mountain for a week, and also parts where they climbed straight up with barely any ice to pick in to. From this documentary, I learned that being a good climber takes both physical and mental strength.]]> 2017-11-20 22:29:25 UTC https://padlet.com/lr1002534/imgvlq06v05f/wish/208913075 lr1002534 https://padlet.com/lr1002534/imgvlq06v05f/wish/208933272 Blog Post by Dr. Michael J. Breus for the Huffington Post 

This blog post provided an introduction to how dreams work and recording methods that have developed with the advancement of technology. I chose this because I am very interested in dreams and how they work, but I don’t know much about them. From personal experience, I know that dreams last a short time after waking up, and the chance of remembering details decreases rapidly within a matter of minutes. Before I looked at the more complicated dream research, I used this blog post to create a strong foundation of knowledge. This blog post confirmed what I experienced; that the chance of remembering a dream after waking up decreases quickly. However, it also taught me potential dream recording methods, such as EEG. EEG reveals detailed data about activity in the brain while it is dreaming. With EEG (electroencephalography), scientists have been able to identify different stages of sleep and activity in specific parts of the brain during a dream. ]]> 2017-11-21 01:11:48 UTC https://padlet.com/lr1002534/imgvlq06v05f/wish/208933272 lr1002534 https://padlet.com/lr1002534/imgvlq06v05f/wish/208944171 Article from Scientific American by Sander Van Der Linden  

In this article, I learned about research done both recently and long ago which has generated theories about how we dream. Recent research conducted by Marzano have shown that most dreaming and the most intense dreams occur during the REM sleep stage. Research has also shown that the neurophysiological mechanisms we use while dreaming are the same as when we are recalling memories awake, therefore the same part of the brain is used. This article was very helpful because it provided many basic but important studies that have advanced dream research. Before reading this article, I didn’t realize that certain brain injuries can prevent dreaming while providing useful information for determining where dreaming takes place in the brain.
