How Do We Taste?

The video explores the science of taste, known as gustation, and how it is a chemosensation that interprets chemical signals from food and drink. It explains the role of taste buds and receptors in detecting five major flavors: sweet, salty, bitter, sour, and umami. The video details the mechanisms behind each taste, including the role of G-protein coupled receptors and ion channels. It also discusses how taste signals are transmitted to the brain and the potential for future research in understanding the subjective nature of taste and its connection to pleasure.
