Very, very interesting presentation! First of all the presenter was very enthusiastic and very fond of what she was researching. She had a lot of different voices and made the presentation more enjoyable than I was expecting. She made a brain presentation really fun to watch. Her power point had a lot of interesting tools and different kinds of animations that made her presentation even better.
Even though her presenting was very well done, her information was also very good. She had a lot of good information that will help college students in the future. She talked a lot about how the brain develops and how we should act to keep our brains in the best shape it can be in.
One thing she really addressed was that alcohol kills brain cells. When a healthy brain learns a new task, it shows a lot of activity, which is what we want to see throughout the teen years. When people drink alcohol the brain slows down a lot. Alcohol is a suppressant drug; it slows-down brain activity throughout the brain. In the teen brain, the Hippocampus and PFC are altered, making it hard to learn and form new memories for a long time. Because it is the formation of new memories that develop us, problems don't show up right away. Alcoholism increases the younger a person starts using it. Teens are 5 times more at risk of having alcoholism. Research shows that during adolescence the brain is changing at such a rapid pace that any interruption in brain activity can have major consequences. The faster the brain is supposed to be going, the more interruptions cost, because it is NOT mature. The teen brain is more vunerable to toxins. Teen brains are so vunerable to addiction that the NIDA has declared alcoholism and other addictions to be developmental diseases, the risks are reduced as a person gets older.
The presenter also showed us a table of brains where it showed how the brain develops. The more yellow and red a brain is the less developed it is. When the brain is purple and blue it has matured and developed. The parts of the brain for safe driving develop last. The basic hand-eye coordination needed to drive develops in childhood, but the parts devoted to expanded attention and focus, judgment, identifying risks and forecasting consequences, risk management, and the complex visual-spatial calculations needed to drive safely develop in late teens and early 20s.
Overall the presentation was very well done. I learned a lot about the brain that I did not know before. There are so many changes that can happen to a brain that I am so amazed by. I did not know that the brain did all of those things.
