Document Summary
How receptor cells in your tongue are organized. Two transduction mechanisms of how they transfer chemical signals into action potentials in your tongue. Neural pathways and how taste related reward signals are organized in the brain. When you think about tasting anything, you do not think of it as being just salty, sweet or bitter, the taste of every food that you experience is a mixture of these multiple dimensions. Must understand how the overall experience of taste from combined primaries, how that really works. Sodium ions in food:your tongue chemo sensors can detect sodium chloride- used for salting most foods. Acids-the key component in sour foods is acidity, the acids can be detected by the chemosensory- important primary sense. Meatiness. -do not consider one of the primaries but it is, the taste called umami- present in lots of meats, some vegetables like mushrooms, has its own sensation, it bitters.
