Sleep-dependent memory triage: Evolving generalization through selective processing

The brain does not retain all the information it encodes in a day. Much is forgotten, and of those memories retained, their subsequent evolution can follow any of a number of pathways. Emerging data makes clear that sleep is a compelling candidate for performing many of these operations. But how does the sleeping brain know which information to preserve and which to forget? What should sleep do with that information it chooses to keep? For information that is retained, sleep can integrate it into existing memory networks, look for common patterns and distill overarching rules, or simply stabilize and strengthen the memory exactly as it was learned. We suggest such 'memory triage' lies at the heart of a sleep-dependent memory processing system that selects new information, in a discriminatory manner, and assimilates it into the brain's vast armamentarium of evolving knowledge, helping guide each organism through its own, unique life.

Sleep for cognitive enhancement (2014, background): “Sleep actively promotes the reprocessing of fresh memories as well as their integration into the pre-existing network of long-term memories (Diekelmann and Born, 2010; Lewis and Durrant, 2011; Stickgold and Walker, 2013).”
Sleep and the Price of Plasticity: From Synaptic and Cellular Homeostasis to Memory Consolidation and Integration (2014, background): “Simulations of hierarchically organized networks indicate that down-selection can also account for gist extraction—a prominent feature of memory that appears to be facilitated by sleep (Inostroza and Born, 2013; Lewis and Durrant, 2011; Rasch and Born, 2013; Stickgold and Walker, 2013).”

The Biology of Forgetting – A Perspective (2017, background): “…sleep enhances the process of consolidation (Cipolli et al., 2013), and perhaps plays an active role in selecting the memories to be consolidated (Stickgold and Walker, 2013), an alternative and recent suggestion is that sleep suppresses intrinsic forgetting, leading to enhanced memory…”
Biologically inspired sleep algorithm for increased generalization and adversarial robustness in deep neural networks (2020, background): “It has been hypothesized that in the mammalian brain sleep helps to create generalized representations of an input learned during the awake state (Stickgold & Walker (2013); Lewis & Durrant (2011)).”
Sleep facilitates memory by blocking dopamine neuron mediated forgetting (2015, positive): “, 2001), and sharp-wave ripplebased memory replay (Wilson and McNaughton, 1994; Ji and Wilson, 2007), that increase memory retention by actively consolidating newly formed memories (Diekelmann and Born, 2010; Stickgold and Walker, 2013).”
