The ted talk I chose for this week’s post titled “The real reason for brains” by Daniel Wolpert. The reason why I chose this ted talk is that the basic information of a brain such as how the brain work is necessary for me to learn neuroscience in psychology class and the title caught my attention and interests.
The speaker talks about that brain evolved to control movements with some examples and own study results. Firstly, he asked us the basic question that “why do we and all animals have brains?”. He also gave an audience the answer that the only reason to have a brain is not to feel something and think, but “to produce adaptable and complex movement”. Robots cannot act like human dexterously although technology is developed because of human control movement by the brain. He suggests that the signal which makes movements from the brain is corrupted by noise. What is difficult for robots is to minimize negative consequences by this noise. The real reason of brain is to control movements which looks simple but so complex as conclusions.
His examples are really helpful to understand his theory easily. For example, he proved this idea that the role of the brain is to move with the example of the humble sea squirt which digest its own brain when it attached the rock and does not need to move. The chess’s example to support his belief that movement is the most important use of brain is also interesting. Robot can beat human when they play chess. However, the robot cannot win five years-old kid in terms of movements of dexterous.
His presentation is trustworthy because he is professional with enough experiences of experiments. There are some steps to support his theory. He clarifies that the brain works for movements at first. Next, the method of combination between several information as belief is explained with Bayes’ rule. He also focuses that people improved movements. These facts which is also trustworthy make his suggestions strong.
The research idea based on the information presented is that how the movements will work better by developments of the brain in the future, and how will it help medical technology developments. We would research how to minimize noise and assume the situations which technology has the skill like a human.
