PSYCH 202 Lecture Notes - Lecture 37: Olfactory Bulb, Olfactory Receptor, Amygdala
Document Summary
Our chemical senses: toothpaste: decreases sweet receptors, increases bitter receptors, toothpaste then orange: bitter orange. Taste: how many basic tastes can you name, sweet, sour, bitter, savory (umami, salty. Flavor = sensory integration: taste + smell + sight + touch (+thoughts!) Sour is on the two sides of the tongue. Salty/sweet are on the tip: bitter is on the back, not many taste buds in the middle. Why tongue map: 1901 drawing; densities of dots = relative intensity of taste - not across taste type! Correct tongue map: bitter, salty, sweet, umami, and sour receptors and cells all overlap, taste bud, collection of taste receptor cells (trc, nestled into the sides of papilla. Labeled-line model: each neuron only receives information from one set of taste receptor cell (following the color). Mice study: they are given plain water and chemical water.
