主　　题：Neural code Taste quality Chorda tympani responses Matrix pattern 

摘      要：The 80 chorda tympani single fibers were selected following the rate of appearance of each response type of units for four taste stimuli in arbitrarily selected 400 fibers in the rat. These 80 fibers were distributed in the matrix with 80 squares in order of the units with sucrose, NaCl, acid and quinine sensitivities from left to right, and also with the intention to make the monotonic function for each quality accomplished by putting the units in appropriate columns. Thus, we could satisfactorily demonstrate the possibility to represent the pictures of across fiber response patterns quantitatively as bar graphs in the matrix. As the matrix patterns for 0.01 M to 0.1 M NaCl were almost the same, the matrix pattern is considered to represent only the taste quality. The matrix patterns obtained for DL-alanine, Na-saccharin, MSG and AgNO 3 were well consistent with results of electrophysiological, behavioral and psychophysical studies.
