Despite the reduced brain matter, the man lived a relatively normal life; he was a married civil servant with two kids. He also scored an IQ of 75 which is considered low but not disabled.
It is also highly unlikely that a brain with so much redundant matter would have evolved in the first place; given the historical risk of death in childbirth associated with the large brain size (and therefore skull size) of humans, [18] there would be a strong selection pressure against such a large brain size if less than half of it were needed.
The human brain requires nutrients obtained from the diet to develop and sustain its physical structure and cognitive functions. [1] [3] [4] Additionally, the brain requires caloric energy predominately derived from the primary macronutrients to operate. [1] [4] The three primary macronutrients include carbohydrates, proteins, and fats.
The concept of "right-brained" or "left-brained" individuals is considered a widespread myth which oversimplifies the true nature of the brain's cerebral hemispheres (for a recent counter position, though, see below). Proof leading to the "mythbuster" of the left-/right-brained concept is increasing as more and more studies are brought to light.

In humans, 90% of the cerebral cortex and 76% of the entire brain is neocortex. [12] For a species to develop a larger neocortex, the brain must evolve in size so that it is large enough to support the region. Body size, basal metabolic rate and life history are factors affecting brain evolution and the coevolution of neocortex size and group ...
Reverse brain drain is a form of brain drain where human capital moves in reverse from a more developed country to a less developed country that is developing rapidly. These migrants may accumulate savings, also known as remittances , and develop skills overseas that can be used in their home country.
According to a study done by Jordan Grafman, chief of the cognitive neuroscience section at the National Institute of Neurological Disorders and Stroke, "the most anterior part [of the brain] allows [a person] to leave something when it's incomplete and return to the same place and continue from there," while Brodmann Area 10, a part of the ...
