Because most of the brain is storage space for a life time of memories, (imo).
Some people suffer encephalitis at birth reducing there brain size, yet lead normal lives.
She is missing most of the left side of her brain which controls all out motor skills and a majority of how we function
There is a misconception that everything to do with being analytical is confined to one side of the brain, and everything to do with being creative is confined to the opposite side, Anderson said. In fact, it is the connections among all brain regions that enable humans to engage in both creativity and analytical thinking.
"It is not the case that the left hemisphere is associated with logic or reasoning more than the right," Anderson told LiveScience. "Also, creativity is no more processed in the right hemisphere than the left."
Anderson's team examined brain scans of participants ages 7 to 29 while they were resting. They looked at activity in 7,000 brain regions, and examined neural connections within and between these regions. Although they saw pockets of heavy neural traffic in certain key regions, on average, both sides of the brain were essentially equal in their neural networks and connectivity.
"We just don't see patterns where the whole left-brain network is more connected, or the whole right-brain network is more connected in some people," said Jared Nielsen, a graduate student and first author on the new study.
The myth of people being either "left-brained" or "right-brained" might have arisen from the Nobel Prize-winning research of Roger Sperry, which was done in the 1960s. Sperry studied patients with epilepsy, who were treated with a surgical procedure that cut the brain along a structure called the corpus callosum. Because the corpus callosum connects the two hemispheres of the brain, the left and right sides of these patients' brains could no longer communicate.
Sperry and other researchers, through a series of clever studies, determined which parts, or sides, of the brain were involved in language, math, drawing and other functions in these patients. But then popular-level psychology enthusiasts ran with this idea, creating the notion that personalities and other human attributes are determined by having one side of the brain dominate the other.
The neuroscience community never bought into this notion, Anderson said, and now we have evidence from more than 1,000 brain scans showing absolutely no signs of left or right dominance.
