The Guardlian - Subliminal messages do leave a mark on the brain, say scientists.
Using brain scanners, they found we often record images we are not even aware of having seen.
The study shows how subliminal advertising, banned in the UK but still legal in the US, might work.
But Bahador Bahrami, a neuroscientist at University College London, who led the work, also found a way to get around the messages, showing that the brain's susceptibility to subliminal messages alters as it works harder. "If the brain is busy ... it can filter out those subliminal things," said Dr Bahrami, whose research is published today in Current Science. His study challenges an assumption of psychology - that attention and consciousness go hand in hand. "We knew the brain responds to subliminal messages but we don't know whether that response is automatic or is affected by whether the brain pays attention."
