Is is often the case... [in mice] The team anesthetized mice, perfused sucrose or sucralose directly into their guts, and then analyzed the response of neurons that make up the vagus nerve using calcium imaging. On average, 40.7 percent responded to sucrose only, 22.2 percent to sucralose only, and the remainder to neither stimulus, explaining how the vagus nerve is able to react differently to the two substances.
