Progressive technology has allowed us to delve into great possibilities that are unattainable in the beginning. Now, it has provided us with ways to read minds. Yes, it is possible to read minds. With the help of brain scanners, it is now possible to detect and recreate the faces of people we are thinking of.
A study has proven that by using brain scans, images of the faces that were previously viewed can be recreated. An fMRI brain scanner can determine brain activity by measuring blood flow in different parts of the brain. Participants are given photos of different individuals. After that, they will be hooked to the fMRI brain scanner.
The 30 brain readings resulted to blurry yet fairly accurate images. Skin color was quite accurate and about 80% detected if the person in the viewed photo was smiling or not. 50% detected the correct hair color and two-thirds determined the gender.
Scientists have admitted that the technology needs more improvement. However, if the technology is perfected, then recording dreams, solving crimes, and understanding mental disorders will not be an issue anymore. The reconstructions are actually based on how the image is perceived by the brain of an individual. Therefore, an autistic person’s reading will be quite different from the perception of a normal person.
Currently, the fMRI brain scanner can only read active parts of the human brain. Scanning for memories are still unattainable since it is in the passive part of the brain. Memory scanning involves very fine details of the brain structure. It might take 2 decades before we can have the right technology to do that.
