Groundbreaking Research Shows That Everyone’s Tongue Is Unique!
Recent discoveries using Artificial Intelligence (AI) and 3D images of the human tongue have revealed that each person’s tongue has a unique surface. This offers unprecedented insight into the biological makeup of our tongues and how our sense of taste and touch differs from person to person.
Experts believe that this research has the potential to revolutionize the way we discover individual food preferences, develop healthy food alternatives, and diagnose oral cancers at an early stage.
Our tongues are incredibly complex and sophisticated organs. They are covered in hundreds of small buds, known as papillae, that play a crucial role in our ability to taste, talk, and swallow.
It has long been known that the mushroom-shaped fungiform papillae hold our taste buds, while the crown-shaped filiform papillae give the tongue its texture and sense of touch. However, little was known about the differences in shape, size, and pattern of these papillae between individuals.
A team of researchers from the University of Edinburgh’s School of Informatics, in collaboration with the University of Leeds, trained AI computer models to learn from three-dimensional microscopic scans of the human tongue, revealing the unique features of papillae.
By feeding the AI tool data from over two thousand detailed scans of individual papillae, taken from silicone molds of fifteen people’s tongues, the researchers were able to gain a better understanding of the individual features of the participants’ papillae and predict their age and gender.
Incredibly, the papillae were found to be distinctive across all fifteen subjects, and individuals could be identified with an accuracy of 48 percent from a single papilla.
This groundbreaking research, published in the journal Scientific Reports, was funded by the United Kingdom Research and Innovation (UKRI) CDT in Biomedical AI and the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation program.
Senior author, Professor Rik Sakar, Reader, School of Informatics, University of Edinburgh, said, “This study brings us closer to understanding the complex architecture of tongue surfaces. We were surprised to see how unique these micron-sized features are to each individual. Imagine being able to design personalized food customized to the conditions of specific people and vulnerable populations and thus ensure they can get proper nutrition whilst enjoying their food.” » …
