Topographic organizations of taste-responsive neurons in the parabrachial nucleus of C57BL/6J mice: An electrophysiological mapping study

Highlights • The majority of sweet-sensitive neurons possessed an umami synergistic response. • Sucrose elicited greater response in the medial and BC than in the lateral division. • Neurons in the lateral division possessed the greatest response to quinine. • The proportion of neuron types in the medial vs. lateral divisions was different. • PbN neurons appear to be more narrowly tuned when estimated by noise-to-signal (N/S) ratio than by entropy ( H ).
