right (after Retzius), showing terminal fibers.

s, gustatory cell; r, sustentacular cell; n, nerve fibers.

then revealed that a single papilla might respond to one taste, all tastes, no 

 taste, or a combination of tastes. It was not, however, until electrophysiological 

 techniques were developed that it became at all possible to determine to what 

 extent each single receptor was sensitive to the hundreds of compounds which 

 are adequate stimuli for the tongue as a whole. And even now the situation is 

 far from clear, because a single fiber may innervate more than one receptor cell. 

 Where a fiber is seen to respond to either of two substances placed on the tongue,
