«Our data suggests that, during development, relative brain parts change their size in response to environmental cues without affecting overall brain size: increasing certain parts forces others to decrease concurrently.

Arnold Kriegstein, a neuroscientist at the University of California, San Francisco, also argues that though the scientists found inhibitory interneurons strikingly depleted in the brains of the oxygen - deprived piglets, this alone can not account for the dramatic shrinking of the animals» overall brain size and the diminished number of cortical folds «The interneurons are part of the story but not the entire story of how the brain is affected by this kind of [lack of oxygen].»
