How transient neural representations become integrated and stable enough to function as internal neural models remains incompletely understood. Grounded in efficient coding, Bayesian and predictive frameworks, recurrent and attractor dynamics, neural state-space models, and systems neuroscience, the Principle of…

Intrinsic neural timescales (INTs) index the temporal decay of neural activity and form a hierarchy from fast sensorimotor to slow transmodal regions. Although altered INTs have been reported in autism spectrum disorder (ASD), it remains unclear whether this hierarchical organization is preserved and how individual…

Detecting novelty is fundamental to adaptive memory, yet the neural comparisons that allow new events to be distinguished from prior experience are not fully understood. Hippocampal novelty signals are often framed as associative comparator responses that register violations of learned relationships. However…

All statistical analyses were performed using IBM SPSS Statistics version 25.0 (IBM SPSS Inc., Chicago, IL, USA). The statistical significance threshold was set at p < 0.05, and all tests were two-tailed. Normality of data distribution was assessed using the Shapiro-Wilk test in conjunction with histogram inspection.…

A fundamental challenge for animals and humans is resolving competing survival demands under naturalistic threat, yet circuit-level mechanisms remain poorly understood. We developed a paradigm recapitulating a predator-prey encounter: Long-Evans rats emerged from a nest to forage in an open arena, choosing between…

REM (rapid eye movement) and non-REM (NREM) sleep stages contribute to systems memory consolidation in hippocampal-cortical circuits. However, the physiological mechanisms underlying REM memory processes remain relatively unclear compared to NREM memory reactivation. Here we report, in rodents, the existence of…
