Neuroscientist Susan Greenfield cited evidence that digital technology is having an impact on our brains:

• A recent paper, Microstructure abnormalities in adolescents with internet addiction disorder, in the journal PLoS (free access).
• Increase in people with autistic spectrum disorders.
• The rise in the appeal of Twitter.
• A review by the cognitive scientist Daphne Bavelier (Children, Wired: For Better and for Worse) in the journal Neuron, in which she says that this is a given, that the brain will change. She also reviews evidence showing there’s a change in violence, distraction and addiction in children, linked to the pervasiveness of technology.
• People are spending most of their waking hours using technology, mostly in isolation.

“We should be planning a 3-D environment for our children [to enjoy] instead of putting them in front of a 2-D one,” she advises.
