Topic: thalamo-cortical spindles

Memory consolidation is assumed to rely on fine-tuned communication within and between hippocampal and cortical neuronal circuits during offline brain states. Sharp-wave ripples (SWRs) have been proposed as the pivotal signature for consolidation, triggering hippocampal replay and information transfer to cortical sites. Critically, although SWRs are precisely coupled to the cardinal NREM sleep-related mesoscopic brain rhythms (i.e., cortical slow oscillations and thalamo-cortical spindles), evidence for a link between SWRs and directed information transfer is scarce. Here, we leveraged the rar
