A bit of pop-sci for anyone interested in recording and replaying dreams.
Writing in the journal Nature, researchers said they have developed a system capable of recording higher-level brain activity.
“We would like to read people’s dreams,” says the lead scientist Dr Moran Cerf.
The eventual aim of Dr Cerf’s project is to develop a system that would enable psychologists to corroborate people’s recollections of their dream with an electronic visualisation of their brain activity.
“There’s no clear answer as to why humans dream,” according to Dr Cerf. “And one of the questions we would like to answer is when do we actually create this dream?”
Dr Cerf makes his bold claim based on an initial study that he says suggests that the activity of individual brain cells, or neurons, are associated with specific objects or concepts.
The researchers will only be able to identify images or concepts that correlate with those stored on their database. But this data base could in theory be built up – by for example monitoring neuronal activity while the volunteer is watching a film.
In the Nature study, the researchers obtained their results by studying patients who had electrodes implanted to monitor and treat them for brain seizures.
While it certainly would be cool to implant electrodes in the brain for replaying dreams how much of our subconscious are we prepared to visualize linearly?
What is experience, what is memory and what is illusion?
Replay comes in scent pellet dream-recall capsules.
