Have you ever been lost in a location foreign to you? Typically, a person who is lost will use a map to gather their bearings before heading off in the correct direction. A similar approach can be used to discuss recent brain mapping technology, the primary research of Dr. Allen Jones. Dr. Allen Jones is a brain research whose ultimate goal is to unveil a complete map of the human brain, using recent brain imaging and histological techniques. In his TED talk entitled, A Map of the Brain, Dr. Allen Jones discusses a brief overview of the anatomical structures of the brain, as well as, the methods and conclusions of his brain research. A fresh human brain does not resemble the stereotypical fixated human brain typically seen in textbooks or diagrams. Instead, a fresh human brain is rich in vasculature, extending across the entire surface of the brain. The brain, in a sense, is greedy, requiring twenty percent of the oxygen coming from the lungs and twenty percent of the blood pumped by the heart. Recently, the brain’s greediness has led to advances in medical brain imaging technology. The PET scan maps the amount blood flow through specific areas of the brain, allowing researchers to localize particular functions to precise areas of the brain. In the TED talk, Dr. Allen explains the function of the cerebellum, temporal cortex, and frontal lobe – areas of the brain whose functions were determined using PET scan. However, brain imaging only gives an anatomical representation
