Delta and theta frequency increases during remote memory retrieval

older age decreases delta and theta frequency increases during remote memory retrieval in humans.

“While remote memory evoked increases in delta and theta (2-7 Hz) frequencies compared to recent memories in both age groups, older adults showed significantly less increase.”
