It's so easy for us that most of us don't notice, but there are really a lot of processes going on in our heads when we activate our imaginations. And it has always been mind reading or even mental control, man has always wanted to understand how to manipulate (and record, and retransmit) someone's imagination.
The phenomenon of imagination and its functioning have been under the lens of Science for decades now: at present, we are still trying to understand which and how many parts of the brain are exactly involved.
Above all, the realm of imagination: us. One of the few truly private things, at least today. In the future this may no longer be the case. In a recent study published in the journal Biology Communications , researchers from Osaka University they developed a way to interpret an individual's imagination by reading their brain waves.
What do we really know about imagination?
In any case, there have already been some discoveries. For example, a recent study found that the visual cortex it is certainly part of the imagination process, because it allows people to "see" things.
It is not the only party involved, it was said. And we don't know them all, this has also been said. But at least others 11 parts of the brain are activated when a person is told to imagine something. For this reason, researchers at Osaka University have hypothesized that a neural network or a sort of "mental office" is involved. And they tried to draw on the strength of this neural network to try to "read" someone's imagination.
Brain wave reading
Researchers at Osaka University studied epileptic patients with electrodes implanted in their brains to try to "read" thoughts. With these electrodes exposed, the researchers worked to develop a new system for recording and reading the electrocorticogram. For friends: brain waves.
Participants were shown one image while asked to imagine a completely different one. The results show a clear difference in brain waves between viewing an image and imagining.
According to the study's lead author, Takufumi Yanagisawa, “The findings clarified the link between brain activities when people look at images and when they conceive them. The electrocorticogram readings of the imagined images were distinct from those produced by the actual images seen by the patients.”
We know when someone is imagining something
Although the researchers were unable to identify what a particular person was thinking when imagining something, the study revealed that scientists could tell whether someone was simply looking at an image, or imagining it.
We are still far (but I can't tell you how much: maybe it depends on which branch of research we consider, including the military one) from reading and mind control. However, it is clear that, albeit slowly, science is advancing in that direction.
You will certainly be better than me at listing all the possible negative implications of this research, but I also see something good: it can be useful for patients recovering from brain trauma, or amnesia.
