The nervous system is made up of cells called neurons. Working together, neurons are responsible for all of your thought and consciousness. Structurally speaking, neurons are made of the same components as other cells, but their complex connections and active nature give us a sense of self. A very famous canadian neurosurgeon names walter graves penfield is actually responsible for the mapping the brain using a technique now called the montreal procedure . He was an american born canadian neurosurgeon. He was responsible for figuring out how epileptic seizures worked. The patient was given a local anasthetic in the head, and the skull was cut open, exposing the brain: the brain was probed in different areas while the patient was awake. This is possible because the brain itself contains no pain receptors: the patient said he smelled burnt toast before his/her seizure, which allowed dr. Penfield to examine and locate the region of the brain causing the seizures.
