Quite right. My comment was too flippant. Yours provided the detail I left out. Without question, it is a worthwhile study and very interesting. But, losing a lobe in infancy and then having the brain compensate is much different, I would think, than having a brain develop in the womb without a lobr. The sibling’s missing lobe, to my mind, is far more indicative of some genetic abnormality as opposed to some acute event in infancy. But, who knows? Either way, she’s a useful data point and hopefully will advance our meager knowledge of the brain.
