Of these numerous projections, the mushroom-shaped fungiform papillae hold our taste buds whereas the crown-shaped filiform papillae give the tongue its texture and sense of touch.

The taste function of our fungiform papillae has been well researched but little is known about the difference in shape, size and pattern of both forms of papillae between individuals.

This enabled the AI tool to predict the type of papillae to within 85 per cent accuracy and to map the position of filiform and fungiform papillae on the tongue's surface.

“Those are the fungiform papillae!”

This sensitivity is genetically based, research has found, and is related in the number of mushroomlike structures on the tongue called fungiform papillae, on which taste buds are perched.
