There is nothing that we do that doesn't require the use of our brain. We need it to smell the flowers outside and would need it at that worst moment when we are asking ourselves "what am I doing with my life"? Neuroscience is the study of the brain and the nervous system. This includes not only the brain but also the spinal cord, the senses and neurons. A neuron is a nerve cell and the human body is made up of more than one hundred billion of them. There are many different reasons why people choose to get into this field but they all believe that this is a fascinating subject worth devoting their lives to.
The nervous system is divided up into a few different parts that all need to function together to work properly. If you're painting some art then your central nervous system will be functioning by telling your hands what to do. They will do this through messages from your eyes. This is just the start of how your brain and nervous system works. While there was a time when scientists thought that we only used about ten percent of our brains, we now know that we need to use it all to do all of the things that we do in life.
While humans might be a lot smaller than other creatures, it is not too difficult to believe that in relation to our body size that our brains are quite large. We are, after all, living in buildings rather than in trees or in holes in the ground like many other species. The human brain takes up about two percent of the body whereas an elephant's brain is only about four times larger in size. That means that in relation to the size of the elephant it is quite small.
There have been amazing discoveries in the world of neuroscience over the past few decades and researching are still finding new things all the time. While you might not think that it is that important to understand how we get around our loft Toronto or how we learn, this research can actually lead to things like cures and treatments for different diseases. This is still a relatively new science and there is much that we can still get out of it.
