The human brain is able to “predict” what your eyes will see before watching it live , has shown for the first time a team of neuroscientists at the University of Glasgow (United Kingdom), describing in the Scientific Reports of Nature how this works mechanism.

The experts used the Functional Magnetic Resonance Imaging (FMRI) procedure to better understand how the brain anticipates the information it will see , even before our eyes move and directly contemplate the object or situation.

The new research, led by Professor Lars Muckli of the University of Glasgow, used magnetic resonance imaging along with a visual illusion to analyze the “constant bidirectional dialogue” of the human brain with a group of participants.

We move our eyes about 4 times per second, which means that our brains have to process new visual information every 250 milliseconds , however, despite all these developments, our world seems stable. Experts believe that the reason we perceive that the world is stabilized is because our brains are able to think about the future.

Experiment with visual illusions

In the experiment, the illusion was composed of two fixed blinking squares that looked at the observer as a square moving between two locations. During the flashes, the experts instructed the participants to move their eyes.

The researchers took images of the visual cortex, the human brain larger part, discovering what and predicting the movement to a new position in space was updated with eye movement, detecting a difference in processing only 32 milliseconds, much faster than you thought.

“Visual information is received through the eyes and is processed by the visual system in the brain.We call visual information ‘direct feeding’ information.At the same time, the brain also sends information to the visual system, this information is called ‘feedback’ Feedback information influences our perception using expectations based on our memories of similar events, both of which interact with each other to produce the visual scenes we perceive every day, “explains Gracie Edwards, co-author of the paper.

Possible help against mental disorders

“This study is important because it demonstrates how FMRI can contribute to this area of ​​research in neuroscience, in addition to that, finding a feasible mechanism for brain function will contribute to computer brain inspiration and artificial intelligence, and will help our research on disorders mental”, concludes Lars Muckli.

The study “Predictive feedback to V1 is updated dynamically with sensory information” has been published in the journal Scientific Reports.
