We live in the 21 century. Computers are everywhere, but our own live neurocomputer is still " a mystery " . Not for all. Science collected impressive material and many questions are already answered. The problem is that different schools used their own approach. Interdisciplinary consideration is needed.

For useful human-like applications, one homogeneous net is not enough. You need to implement a number of them and link properly. How? Read this book. The human brain definitely has memory, but does it have a processor? This edition adds the chapter about the limbic system.
