Taste response profile A: Heat map showing responses of 178 PbN neurons to taste stimuli. Response profiles of PbN taste neurons by heat map. Taste neurons were grouped into best-stimulus categories and arranged within those categories in descending order of response magnitude to the best-stimulus [n = 178; 76 sucrose (S)-best; 59 NaCl (N)-best; 24 citric acid (C)-best; 19 QHCl (Q)-best]. Taste responses are presented as net responses (i.e. responses to stimulus - responses to water). B: Mean net taste responses of each neuron type. C: Dendrogram showing neuronal grouping. Each symbols indicate the neuron type based on neuron’s best stimulus (circle) and umami synergism (star).
