"We originally aimed to look at how sense of taste works with thermal sensation in this study to better understand how taste is connected to food preferences, health and well-being. Taste is also closely tied to emotion and understanding how the brain processes different tastes is significant on several levels," said Christian Lemon, principal investigator on the grant and associate professor in the OU Department of Biology, OU College of Arts and Sciences. "What we found was a surprise because temperature signals were converging with taste near the mid-brain, but so were neural messages for taste and pain."
Lemon and Jinrong Li, OU research associate, used a molecular biology and physiology technique to understand how taste and thermal pathways might be converging with pain. What OU researchers learned...
