Zhou et al. introduce cascading neural activations, known as 'replay', into a context-maintenance and retrieval model (CMR) that has been previously used to capture a range of memory phenomena. The proposed 'CMR-replay' model outperforms its CMR predecessor in a compelling way, and thus, the work makes important strides towards understanding the empirical memory literature as well as some of the cognitive functions of replay. Notable limitations include the scope of the model with respect to established aspects of memory consolidation, such as the stages and physiology of sleep, and the lack of integration with highly relevant associative and deep learning theories.
