Transient bursts of activity such as hippocampal ripple oscillations, amygdala high-frequency oscillations, and prefrontal cortical ripple oscillations are used in the brain to make memory “stick” to current memories.

Brain waves, Sharp-wave Ripples, SWRs from low intensity electrical stimulation
Some brain waves look like Sharp-wave Ripples, these are sometimes called SWR’s.
SWRs can be evoked by low intensity electrical stimulation, and at lower intensities than those needed to evoke detectable population spikes. In addition, evoked SWRs show large variability in amplitude, similar to that of spontaneous events. See more at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5862867/
Hippocampal sharp-wave ripples (SPW-Rs) support consolidation of recently acquired episodic memories and planning future actions by generating ordered neuronal sequences of previous or future experiences. See more at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6310484/
