FETID:

A． illustrating the extent to which the physiological principles behind taste mirror those behind vision
B． contrasting the available evidence for the labeled-line and across-neuron theories of taste
C． describing the evolution of theories concerning the neurological mechanisms which determine taste
D． demonstrating the superiority of holistic models over component models in analyzing neuron function
E． showing that individual neurons play a negligible role in the physiological mechanisms of perception

A． A group of taste neurons is found which only responds to sweet taste when stimulated by sweet foods.
B． A brain-wave analysis of a rat genetically engineered to lack a sense of sweet tastes is nevertheless found to have a sense of sour tastes.
C． Most tastes are found to have strikingly different neurological effects on humans they do upon animals.
D． A brain-wave analysis of a hamster demonstrates a similar pattern of activity in a given neurological area for both sour and ,sweet stimuli.
E． A group of taste neurons is found which provides insufficient information for taste discrimination.
