Study Suggests Our Brains Have a ‘Sixth Sense’

Scientists may have discovered a “sixth sense” that relates to something called numerosity, which involves the ability to rapidly assimilate the number of objects within one’s field of vision. The team behind the study used fMRI scans to highlight the activity of a key area of the brain, which seemed to alter its response based upon the number of objects perceived.

Dubbed a “number sense,” the phenomenon is believed to manifest in a part of the brain called the posterior parietal cortex, situated around the crown of an individual’s head. The study’s lead researcher, Ben Harvey, who works at the Utrecht University in the Netherlands, explained that most people don’t need to methodically count a small number of objects presented to them, “… we just know how many there are straight away.” This has led many people to maintain that a person’s numerosity powers represent something akin to a “sixth sense.”
