SPW-Rs are described as highly synchronous hippocampal population events that arise from CA3-driven sharp waves and produce ripple oscillations in CA1. The review links them to replay of waking neuronal sequences in compressed form.

SPW-R replay combines recently acquired and pre-existing information to influence decisions and plan actions.
SPW-Rs support memory consolidation by transferring compressed hippocampal representations to distributed circuits, and selective disruption of SPW-Rs interferes with memory.
The spike content of SPW-Rs is coordinated to replay fragments of waking neuronal sequences in a compressed format.
Hippocampal sharp wave-ripples arise from the excitatory recurrent system of CA3, and sharp-wave-induced excitation produces a fast ripple oscillation in CA1.
Altered physiological mechanisms can convert SPW-Rs into pathological p-ripples that mark epileptogenic tissue and are observed in rodent models of schizophrenia and Alzheimer's disease.
