Understanding Genetics: A Primer for Couples and Families Book

It's very odd that after playing the computer adventure game "Gray Matter" I suddenly get hold of a book dealing with neuro(psyscho)logy. The consequence of this is that inside my head all the text was read to me by Steven Pacey, who does the voice of the character David Styles in said game.

The book makes me think of the version of Sherlock Holmes played by Benedict Cumberbatch, where he often retreats into his "mind palace".

This book talks about how a biologist, a physicist and a philosopher try to explain how the human brain stores everything we see, hear and do, in such a way that we can retrieve them sometimes even decades later. Intriguing, but the book dates from 1991, and I wonder how far science has advanced since then, and what we are capable of today, as well as in making it easier to remember, as in blocking bad memories.
