Neurology: All in your Head

Space is 92 billion light years in diameter and ever growing. Despite it’s size, there is more knowledge about this massive area, miles outside the atmosphere, than there is about the cluster of tissue and nerves that is called the brain. With the immensely complex structure of the human brain, it is not surprising that from conception to old age many things can become faulty or even just fail to develop correctly in the first place.

Separating the brain into the three main parts gives a much better idea as to how the brain functions. These three parts are the cerebral cortex, the brain stem and the cerebellum. The brain stem is the terminal from the brain to the body. This is where the brain will receive information from the body and then send out signals back to the body to tell it the correct response. When it comes to everyday reaction and natural bodily functions, the cerebral cortex will kick in, made up of pretty much all “grey matter.” The cerebral cortex is the hub for most of your reactions and memories. The cerebellum is mainly responsible for regulating the levels in the body, organizing the information and memories the brain receives and it also controls with the “thought process.”(brains and interactions, NP BBCsci.)

Coming in at an average of three pounds, the human brain is made up of a grouping of fats and proteins. The brain works by firing “trains” of the almost 100 billion neurons it has in it so it can put together large electrochemical signals, which in turn will be sent out of the brain stem and the body will react how it is told to by the signals. Neurons are made up of five parts, the soma, dendrites, axons, the axon terminal and the neurons itself, information is received by the dendrites w...

...re, innovation to speculation, the human brain is a jumble of nerves and tissue like no other. It has not only brought humans to the front of the world stage in comparison to all others, it has given us the ability to do so much more than think it gave us the ability to be human.
