Taste Coding In The Hippocampus

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.
