I've recently read a very interesting and, while intuitive, very indepth book on the subject of brains, and brain evolution/commonalities. It covers reactions, active choices, responsibilities, creativity, memory, sleeping patterns, learning and much more.
It's written by a famous Danish brain surgeon, and unfortunately written in Danish.
It's called "Dr. Zukaroffs Testamente" (an intertwined story following the books 500 pages explanations, making it easier to digest), by Peter Lund Madsen.
Why am I commenting even though it's in danish? Because it truly is an amazing book, and one I would've loved to read back when I was deciding which path to choose in life (medschool or other), and in the hope that we may be able to push for an English translation.
If you have any means of reading a Danish book, it's genuinely worth it.
