@lobotomize-me interesting, thanks. There are good points, but there are also some things I disagree with or want to add nuance on.
It would be wrong (depending on context) to say that there's increased right hemisphere activity, but I don't think it would be wrong (although not the whole picture) to say that there's increased access to (or reliance on) right hemisphere functions. There's a difference there.
While the left hemisphere is often thought of as analytical and logical, the right hemisphere is also involved in reasoning, including in deductive reasoning and some types of mathematical reasoning.
This is a better summary of the main differences between the hemispheres:
@NoeticJuice said in Quotes from books:
"If one had to encapsulate the principal differences in the experience mediated by the two hemispheres, their two modes of being, one could put it like this. The world of the left hemisphere, dependent on denotative language and abstraction, yields clarity and power to manipulate things that are known, fixed, static, isolated, decontextualised, explicit, disembodied, general in nature, but ultimately lifeless. The right hemisphere, by contrast, yields a world of individual, changing, evolving, interconnected, implicit, incarnate living beings within the context of the lived world, but in the nature of things never fully graspable, always imperfectly known — and to this world it exists in a relationship of care. The knowledge that is mediated by the left hemisphere is knowledge within a closed system. It has the advantages of perfection, but such perfection is bought ultimately at the price of emptiness, of self-reference. It can mediate knowledge only in terms of a mechanical rearrangement of other things already known. It can never really 'break out' to know anything new, because its knowledge is of its own representations only. Where the thing itself is 'present' to the right hemisphere, it is only 're-presented' by the left hemisphere, now become an idea of a thing. Where the right hemisphere is conscious of the Other, whatever that may be, the left hemisphere's consciousness is of itself."

There's of course much more detail to be added about the differences, which is why there's an entire book (or half of a book) about it.
