Heatmaps depict z -score-normalized fluorescence traces from IL-10-responding TRPA1 vagal neurons. Each row represents the activity of a single cell over 15 min. The experiment was carried out using intraperitoneal injection or perfusion with similar results. n = 6 mice. Pro: IL-6, anti: IL-10. A total of 27 of 189 imaged TRPA1 neurons responded to IL-10.
