Forget about the possibility of developing a sixth sense! We’re taught from our earliest years that we have five senses, but according to a recent study published in the Journal Current Biology, we may actually only have one. Neuroscientist, Don Katz, of Brandeis University suggests that smell, hearing, taste, sound and sight may all spur from one central system. In the study, Katz demonstrated what happened when a rodent’s sense of taste was shut down. Not only did he see an instant impact on the transmission of neurons involving smell, but he also discovered that the impact was so great that the rat could no longer identify once familiar odors. These findings indicate that human senses may all be connected to a single system. Perhaps everything really is an illusion!
