Sensation and Perception 9th Edition by Bruce Goldstein

Exercise 1

Consider the kinds of food that you avoid because you don't like the taste. Do these foods have anything in common that might enable you to explain these taste preferences in terms of the activity of specific types of taste receptors?
Figure The blue lines show how two neurons in the rat NST respond to a number of different taste stimuli (along the horizontal axis). The neuron in (a) responds strongly to compounds associated with salty tastes. The neuron in (b) responds to a wide range of compounds. The purple lines show how these two neurons fire after the sodium-blocker amiloride is applied to the tongue. This compound inhibits the responses to salt of neuron (a) but has little effect on neuron (b).
