The nervous system is a vast network of cells that controls almost everything our body does. Many of the nervous system's functions are not yet fully understood. This is why neuroscience is growing. Neuroscientists study how the nervous system functions and how it affects the body's biology, behavior, sensory systems, thought processes, diseases, and much more.
Neuroscience has been around for several thousands of years. The ancient Egyptians believed that the brain did not control intelligence; rather, intelligence was concentrated in the heart. This explains why the brain was usually removed before mummification. Much later, Greeks and Romans began theorizing that the brain was responsible for processing senses and thought. In the 1890's, single neurons began being observed due to the development of the microscope and staining procedures. Even though neuroscience has taught people quite a bit about the nervous system, there is still a large amount that people do not fully understand. There are several subgroups of neuroscience. For example, behavioral science studies physical behavior, the effects of chemicals, and sensory processing. In addition, psychology is a small portion of cognitive neuroscience, and studies social behaviors, learning, emotions, and many more functions.
Neuroscience is a broad field of study that encompasses many aspects of the human body. It seems that each individual section of neuroscience has a special way of observing it. The study has come a long way from the views of the Egyptians. In a few thousand years, there is a good chance that people will look at what we know today as rudimentary.
