Chemical Control of Brain

In the lecture this week we continued with the neurotransmitters that we also addressed last week. The topic was chapter 15, which nicely combined what we have learned so far and how it concretely affects the brain. There was also an introduction to the mechanisms behind Parkinson’s disease and Alzheimer’s disease, which was very interesting. The videos could be broadcasted through Zoom this time, unlike last week, which was nice. Getting concrete examples of how the brain works makes it easier to stay motivated when studying.

Since there are so many new details, it is hard to remember them all. This could also be a problem later, affecting the learning, if the information from previous chapters is forgotten. In order to remember the information better, one of the group members tried to draw some of the pictures in the book by herself. This could make it easier to remember the details better.

There was an interesting question during the lecture, about the duration of dopamine in the body. When dopamine is secreted, how long does the effect last? And what about adrenaline? Do we know anything about its duration in the body? We also wonder how the change between the parasympathetic and sympathetic nervous system happen? Is it possible that one of the systems affect one part of the body and the other affects another part of the body at the same time?
