| Justin D Shin, Shantanu P Jadha. Prefrontal cortical ripples mediate top-down suppression of hippocampal reactivation during sleep memory consolidation. Current biology : CB. 2024-06-04. PMID:38834064. |
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 slow and spindle oscillations during non-rem sleep. |

| Edmund T Rolls, Alessandro Treve. A theory of hippocampal function: new developments. Progress in neurobiology. 2024-06-04. PMID:38834132. |
key new computational developments include the capacity of the ca3 attractor network for storing whole charts of space; how the correlations inherent in self-organizing continuous spatial representations impact the storage capacity; how the ca3 network can combine continuous spatial and discrete object and reward representations; the roles of the rewards that reach the hippocampus in the later consolidation into long-term memory in part via cholinergic pathways from the orbitofrontal cortex; and new ways of analysing neocortical information storage using potts networks. |
