Period 2 week 3
Unfortunately, I was not able to be present at the lecture so the amount of questions that arose was much more significant. Even though subplate neurons “disappear”, they are still connected to various diseases/injuries and this is deemed to be quite selective which cause negative effects in cognitive and motor functions. Is this an effect of direct injury or the effect of “injury spreading”?
The figure on cats developing neurons in layers was very interesting – again a perfect example of general functionality adaptation. No need to create something that is not deemed “useful” and the other way around.
Neuroplasticity, of course, plays an important role in the development of the brain. If we can find the principles of plasticity, I think they could be leveraged for people, for whom the critical period has already ended. Inducing plasticity would open up a door to both treat brain damage and give us a way to develop, for example, the teaching methods at schools.
Dr. Huberman, a neuroscientist at Stanford, recently talked at an educational event by Logitech about leveraging the current knowledge in brain plasticity to make learning easier. This is especially interesting for young adults such as us, who have (probably) recently seen a shift in their learning. Back in primary school I remember things just sticking into my head, whereas now, learning needs more effort. One important aspect of learning is focus, which I suppose we will learn more about next week, when we talk about mental illnesses, in case ADHD will be one of the topics.
