Herzog LE, Pascual LM, Scott SJ, Mathieson ER, Katz DB, Jadhav SP (2019), “Interaction of taste and place coding in the hippocampus”, Journal of Neuroscience, 39(16), 3057-3069.
This study reported the discovery of taste-responsive place cells in the hippocampus. A subset of place cells with weak spatial responses discriminated between tastes based on palatability. The hippocampus thus overlays existing mental maps with information about the hedonic values of tastes, providing a mechanism by which animals can use past experience to locate food sources.
