Refinement And Reactivation Of A Taste-Responsive Hippocampal Network
Herzog LE, Katz DB, Jadhav SP (2020), “Refinement and reactivation of a taste-responsive hippocampal network”, Current Biology, 30, 1306-1311. This study followed up on the discovery of a taste responsive hippocampal sub-network to examine changes in this network during novel taste experience. Our results showed that taste responsiveness is associated with initially larger spatially responsive place …

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 …
Hippocampal-Prefrontal Network For Memory-Guided Decision Making
Jadhav SP*, Rothschild G*, Roumis DR, Frank LM (2016), “Coordinated excitation and inhibition of prefrontal ensembles during awake hippocampal sharp-wave ripple events”, Neuron, 90(1):113-27. doi: 10.1016/j.neuron.2016.02.010 This study showed that awake SWR replay during quiet waking states (when animals are inactive) corresponds to mental replay of ongoing spatial experiences. The hippocampus, the brain’s memory hub, communicates …

Coherent Spatial Coding Mediated By Theta Oscillations
Zielinski MC*, Shin JD*, Jadhav SP (2019), “Coherent coding of spatial position mediated by theta oscillations in the hippocampus and prefrontal cortex”, Journal of Neuroscience, 39(23), 4550-4565. This study established that theta oscillations mediate a temporal coordination mechanism for coherent coding of spatial position in hippocampal-prefrontal networks during memory-guided behavior. We found that ensemble activity in the …

Awake And Sleep Replay
Tang W, Shin JD, Frank LM, Jadhav SP (2017), “Hippocampal-prefrontal reactivation during learning is stronger in awake as compared to sleep states”, Journal of Neuroscience, 37(49): 11789-11805. This study that revealed a surprising difference between awake and sleep replay. Despite the dogma that sleep replay is primarily responsible for reactivating memories of our experiences for permanent …
