Structure and function of neurons

The introduction to neurons included both familiar and new information based on the previous studies in Bioinformation Technology. The structure and the basic functions of the neurons were already familiar but the information about the differentiations of neurons and function of glia cells were new. The history behind how all this information has been found is really interesting. I am constantly amazed by how the scientists have been able to develop the research and methods this far.

I had some difficulties understanding the ion channels and pumps, or more like why the cells will always have the resting potential less or more than zero. Why the body wants to use ATP and extra energy to maintain imbalance between different sides of the membrane. I understand how in the book it is stated that the cell needs this in order to survive, but the basic idea behind this is still a bit unclear.

One other thing I was wondering, why it is predicted that the scientists might not be able to find a treatment solution for Alzheimer’s disease? Why it is so difficult to find a solution that would prevent the building up of amyloids? Science has reached so much during the past decades so it surprises me that there might not be an answer to this problem.

I felt that the exercise session was well designed to encourage us to connect the theory and practise. For example the assignment to think what would happen without cilia cells really pushed us to use these new learnings of their functions and what would happen if they did not exist, what would happen without these functions.
