A research to visualize the image of "human face" drawn on the head is underway at Yale University

It is often awkward to not be able to convey the image drawn on the head well to others, but the day when the image in the head can be reproduced in the image may come. At Yale University, "Researching the image of" human face "that remains in memories" is proceeding.

Alain Cohen, majoring in cranial neuroscience at Yale University's master's course, maps the image drawn in the head by examining what kind of reaction is occurring in the brain when a person distinguishes the face of others I am studying technology.

Research on discriminating images drawn on the head by analyzing the human brain so far has been conducted, and as a result of research on the part of the brain that is activated when viewing the image and its reaction, for example, see It is already possible to judge whether something is an animal or a building. However, for example, concrete images such as the "human face" envisioned on the head are extremely difficult to distinguish and map accurately as individual faces are very similar to each other.

Therefore, the joint research team of Cohen and co-researcher Blythe Kool of New York University divided the face of the person into six kinds according to its characteristics, and the image of the face of a total of 300 people was taken as a subject I showed one after another to the brain's reaction at that timeFMRIIn real time to make a database of which parts of the brain are reacting to which features of the faceMachine learningBy mapping and scoring using algorithms, we attempt to reproduce the image of the face from the reactions occurring in the brain using a large amount of mapping data collected.


Although the precision of reproduction seems not to be high yet, the research team believes that accuracy can be improved by gathering more data, and by applying this technology, for example, I think that it may be possible to know the state in the patient's mind.

Research to realize the image drawn on the head has just begun and the reactions occurring to the brain by individuals are also different, so there are many problems. It is expected that it will take a long time to be able to visualize the image of the head accurately, but someday it may be possible to make images of the events in the mind as images.
