| Nakul Yadav, Andrew Toader, Priya Rajasethupath. Beyond hippocampus: Thalamic and prefrontal contributions to an evolving memory. Neuron. 2024-01-25. PMID:38272026. |
by synthesizing studies across the rodent and human literature, we suggest that as memory representations initially form in hippocampus, parallel traces emerge in frontal cortex that cue memory recall, and as they mature, with sustained support initially from limbic then diencephalic then cortical circuits, they become progressively independent of hippocampus and dependent on a mature cortical representation. |

our model revealed an elegant circuit mechanism that mediates an affective "inverted u" phenomenonv: there is an optimal level of amygdalar input that enriches hippocampal context representations, but on either side of this zone, representations are impoverished. |

| Justin D Shin, Shantanu P Jadha. Cortical ripples mediate top-down suppression of hippocampal reactivation during sleep memory consolidation. bioRxiv : the preprint server for biology. 2024-01-03. PMID:38168420. |
consolidation of initially encoded hippocampal representations in the neocortex through reactivation is crucial for long-term memory formation, and is facilitated by the coordination of hippocampal sharp-wave ripples (swrs) with cortical oscillations during non-rem sleep. |

here, we record from single neurons in the human amygdala and hippocampus and find a greater neuronal representational distance between pairs of familiar faces than unfamiliar faces, suggesting that neural representations for familiar faces are more distinct. |

empirical evidence shows that memories that are frequently revisited are easy to recall, and that familiar items involve larger hippocampal representations than less familiar ones. |

these changes can reflect increased (integration) or decreased (differentiation) overlap; previous studies have posited that the amount of coactivation between competing representations in cortex determines which will occur: high coactivation leads to hippocampal integration, medium coactivation leads to differentiation, and low coactivation is inert. |
