Hippocampal sharp-wave ripples correlate with periods of naturally occurring self-generated thoughts in humans

T. Iwata, T. Yanagisawa, et al.

This groundbreaking study by Takamitsu Iwata and colleagues delves into the brain's inner workings, revealing a fascinating link between hippocampal sharp-wave ripples (SWRs) and our self-generated thoughts. With insights from long-term EEG recordings of epilepsy patients, the research highlights how these brain signals play a role in our most vivid and imaginative cognitive states.

Abstract

This study investigates the brain mechanisms underlying self-generated thoughts, hypothesizing a link between hippocampal sharp-wave ripples (SWRs) and these cognitive states. Long-term EEG recordings from 10 epilepsy patients with hippocampal electrodes revealed higher SWR rates during periods of vivid, less desirable, and more imaginable thoughts, less correlated with external tasks. This suggests a role for SWRs in the generation and experience of self-generated thoughts in daily life.
