For many years, neuroscience has been an exciting field of Biology for various reasons. One of the major reason is, very little is known about the brain and its functions.
Brain is a complex organ with billions of cells, and they make zillions of connections.
Despite these conceptual and semantic difficulties, comprehending the brain is feasible - if some basic facts, and terminology are understood. That is exactly what we are going to start with in this course. Neurons are specialized for electrical signaling over long distances. Glial cells are not capable of electrical signaling - their main function is to support neurons. In most respects, the structure of neurons resembles that of other cells.
