Not a teenager? Not to worry! It turns out that surfing the web is just as good for everyone else, too.
Each volunteer underwent a brain scan while performing web searches and book-reading tasks.
Both types of task produced evidence of significant activity in regions of the brain controlling language, reading, memory and visual abilities.
However, the web search task produced significant additional activity in separate areas of the brain which control decision-making and complex reasoning - but only in those who were experienced web users.
Yay for not ending up like this guy!
