Researchers at the University of Michigan have used the anesthetic drug propofol to identify the intricate brain geometry behind the unconscious state, offering an unprecedented look at brain structures that have traditionally been difficult to study.
The study identifies two common forms of variation in human brain networks: border shifts and ectopic intrusions.
Border shifts involve changes in the borders between functional areas, while ectopic intrusions are shifts in brain organization at remote locations.
Both forms of variants are heritable but differ in their location, network associations, activations during tasks, and prediction of behavioral phenotypes.
