Neurologists at the University of California started by matching patterns of activity with static images as seen by a volunteer. Now the scientists say their research has evolved to the point where it is possible to ‘decode’ the signals in the brain.
The experiment then used functional magnetic resonance imaging (fMRI) technology to scan the brains of two patients as they watched videos. The neurologists then linked the patterns of the activity in the visual cortex of the brain with the movement and colours of the footage.
This information was used to program software that was able to display a blurry 'mind's eye' version of the footage of the films the patients were watching.

Longer limbs 'mean less risk of dementia'
Leggy women and gangly men are less likely to develop Alzheimer's, according to a study that suggests a healthy upbringing protects against the degenerative disease. Researchers took limb measurements of 2,798 men and women with an average age of 72 and monitored them for five years. At the end of the study 480 had developed Alzheimer's or other types of dementia.
Leading thinkers predict technologies that will turn the world upside-down
Flying cars, personal jetpacks, holidays on the moon, the paperless office – the predictions of futurologists are, it seems, doomed to fail. The only thing predictable about the future is its unpredictability.
