Week 45

This week I focused on learning chapter 9 as I didn’t have time to study it before. I study computer science and it was interesting to find how eyes are similar to pixels or RGB values on a monitor. – Kyösti

  • Write your thoughts about the lectures, exercises and laboratory visits.

I had a fever this week and couldn’t participate in the exercise session and couldn’t study much during the week. The hybrid lecture was nice and the sound quality was good and I hope hybrid lessons continue. One wish that I have is that the lecturer would repeat the question that was asked in class as it can’t be heard in the stream. -Kyösti

I didn’t attend lectures or exercise sessions this week. -Martti

  • Present questions you would like to ask from the experts.

I didn’t quite understand why the eye evolved in a way that the photoreceptors are inside-out – they are “behind” ganglion cells and bipolar cells. – Kyösti

How exactly do cells know what kind of cells to be when they evolve? How do they know to be neurons? -Martti

  • Make observations, and introduce new ideas that are based on what you learned.

I was reading about autism in the book (Box of special interest “The Mystery of Autism”) and learned a lot of new interesting stuff about it. I knew some of the symptoms like social awkwardness but didn’t know that at the most severe end of the spectrum autistic people may never even develop language. This made me broaden my understanding about autism. -Martti

  • Tell how what you learned is related to what you already know.

I studied lots of physics in upper secondary school and it was really interesting to see how both the actual topic of this week (sound / audition) and the topic I mostly studied this week (optics / eye) are “transformed” from the physics way of thinking into our brain. – Kyösti

  • Discuss conflicts with what you already knew, and possible problems in the learning experience.

I didn’t have time to study the whole chapter before the lecture so the parts that I hadn’t read about before were hard to follow during the lecture. – Kyösti

  • Ask the ‘so what?’ question: Why is this important, and can I apply it somehow?

I also studied cell death this week. Why is it important to know how and why neurons die? The answer has probably something to do with tackling Alzheimer’s or other diseases that devastate the brain and its cells. If the cause of death of neurons is known more clearly, diseases like that might be able to be prevented more easily.
