Looking for a title to scifi book ? - Help

I recently started reading a book that my son had brought home from school.
It was quite interesting, but half way through reading, it disappeared. ( Went back to school)
I had a search, but can not find the book, or its title.

Storyline
Earth has been in a region of space which slows down human thinking.
As it emerges from the cloud/area people start to get smarter.
Clever people become genius.
Dumb people become very clever.
Even animals get smarter.

The book cover may have an image of a layered human head on.
ANY IDEAS?

No, never read that book, but good luck. I've been in that situation before a couple of times - remembering the story of a book I've read and even the cover, and resorting to asking people on DV.

Wouldn't the easiest thing just be to ask your son?

If you remember a sentence with some not so common words in it, have you tried googling for that sentence? It may show you hits from Google Books or some pdfs.

Good idea
I will have a go.

Is it Brain Wave by Poul Anderson?

And the "ORIGINAL POSTER" does it again.
Thanks mate.
Have you read the book, or just a Google search specialist ?

I'd heard of it before, it's on my reading list.

You will love the bit about the addict, sitting in a doorway, depressed, pondering the meaning of life.

Let me know, when you have read the book. Your opinion would be most welcome, as you seem to be one of the smarter peeple on here

Whoa, I am reading "Call me Joe" by Poul Anderson, which Avatar ripped off even worse than any other item. If you like his style, check that out.
