Introversion and Neurodicism - Isaac, Gray, and Andnd

Isaac identified extraversion and intraversion, or extraversion and neurodicism. He was a master of the animal experimental literature. A lot of that's being phazed out of universities because regulations for animal experimentation have become so onerous they're easier to not bother with. And we've learned very little about the br an from pet scans and amorai scans in humans. We can learn unbelievable amount by studying animals. So anyways, back to isaac, and then back to geoffrey gray.
