How brain controls vision and what we miss to see


The frontal cortex is often seen as our “thinking cap,” associated with thinking and making decisions. But it’s not commonly connected with vision.

“Some people believe that the frontal cortex is not involved. The new research adds to previous evidence that it is,” said Dobromir Rahnev, psychologist at Georgia Institute of Technology.

“The ‘thinking cap’ of the brain controls and oversees the whole process, making it as essential to how we see as those other areas,” Rahnev explained.




Sometimes the frontal cortex is not expecting to see something so although it’s in plain sight, it blots it out of consciousness, said the team that involved researchers from the University of California-Berkeley.

The frontal cortex sends a signal to move your attention onto the object you select.

“It does some of the combining with other information, and then it’s probably the primary evaluator of what you think you saw,” Rahnev noted.

The findings were published in the journal of the Proceedings of the National Academy of Sciences.
