Introduction to neuroscience

Welcome to our first post of the blog series on the journey of learning about human brain. This blog is written by three students as a part of a course called ‘Structure and operation of the human brain’. In our group of three students we have varying prerequisite knowledge on the topics, but share the same motivation for learning more from each other.

The first week of the course included introduction to the neuroscience in general, and some topics about neurons and glia. As this weeks writer, I didn’t have much prerequisite knowledge about the previously mentioned topics. These topics, however, are introduced clearly in a book called ‘Neuroscience: Exploring the brain’ by Bear, Connors & Paradiso. This course most likely requires a lot of anatomy studies at least on my part, but the book has seemed to be easy to read and to grasp concepts.

The most interesting thing to me was how ions are passed through the neuronal membrane and the selectivity filter. Its fascinating to think how minuscule the reactions are but how important role they nonetheless play in the well being of a human. For example, in the book it was noted that some forms of epilepsy are explained by mutations of specific potassium channels. Fine detailed example like this shows how complex and delicate system brain really is, and I’m more than curious to see what new things we discover next week!
