OBS: We Can Soon Be Reading People’s MINDS As Scientists Invent Software That Uses Brain Scans To Identify Exactly What People Are Looking At…

Test yourself with simple IQ Questions


From lie detectors to mind reading software, it seems scientists will soon be able to tell what exactly we are thinking in our heads—-and that will be the end of our privacy.

Who wants someone to know what he/she is thinking about? It is thought for a reason…

According to MailOnline;

Researchers are a step closer to being able to read people’s thoughts after creating a computer program that can identify what someone is looking at using brain scans.

A team from Radboud University Nijmegen in the Netherlands used image and shape recognition software and a specially designed algorithm to assess changes in a person’s brain activity using functional magnetic resonance imaging (fMRI) technology.

During tests the scientists showed participants a series of letters and were able to identify exactly when, during the scan, they were looking at which letters.

Functional MRI scans are traditionally used to measure changes in overall brain activity, yet the Dutch researchers used the technology to zoom in on smaller, more specific regions, known as voxels, in the occipital lobe.

These voxels are around 2x2x2 millimetres big and the occipital lobe is the part of the brain which reacts to visual stimuli and processes what the eyes see through the retina.

Each participant was wired up to an fMRI scanner and shown the letters B, R, A, I, N and S on a screen in front of them.

The scientists were able to create a database of the specific changes that occurred in each person’s brain after each letter was shown, which highlighted how the brain visualised the different shapes.

These changes were run through a bespoke algorithm that had been designed to work in a similar way to how brains build images of objects from the sensory information it receives.

This algorithm was able to convert the voxels, and their relevant changes, into image pixels, making it possible to reconstruct a picture of what the person was looking at, at the time of the scan.

The model has been designed to compare letters, yet could be expanded for other imagery.

Marcel Van Gerven, co-author of the study ‘Linear reconstruction of perceived images from human brain activity‘ said that the algorithm is also capable of becoming more accurate the more times it is used and more data it processes.

This experiment used information obtained from a selection of 1,200 voxels, yet van Gerven claims the algorithm could also be used to reconstruct any image and his team is working on building more advanced machines that can build images from 15,000 voxels.

This could include complex imagery such as a person’s face.

During an interview with Wired, van Gerven did warn that this isn’t exactly the same as reading a person’s thoughts and more work and understanding about how the brain processes internal images would need to be carried out before being able to decode thoughts.

Yet he added that if its discovered the brain reacts to imagination in the same way it reacts to physical visual stimuli then mind-reading would be possible, potentially leading to so-called telepathic computer programs.
