Evolution Shapes the Brain's Form

A study by the Medical University of Vienna examined 3D surface models of the brains of 90 species of Euarchontoglires, including humans, macaques, mice, rats, squirrels, and hamsters, to analyze the diversity of brain forms and their relationship to function, behavior, and ecology. The study found that the shape of the brain has developed in parallel with its function throughout the course of evolution. The brain adapts to its environment by first expanding its visual attention areas before other areas involved in higher cognitive functions, such as language and memory. The research outcomes could aid in better understanding the common and different characteristics between animals and humans.
