Think of all the wonderful sensations taste can impart to us - the delicious Thanksgiving turkey and gravy, mashed potatoes, cranberry sauce and pumpkin pie! Coffee, chocolate, lush strawberries - the list goes on and on! Receptors on our tongues bind to chemicals in our food and relay the information about the chemicals to our brain. Surprisingly, all those wonderful tastes are transmitted to our brains through only four types of receptors on our tongues - those for sweet, sour, salt and bitter. How can this be so?
