From ripples to daydreams: The brain activity behind mind wandering

Researchers have found that a specific pattern of brain activity, known as 'sharp-wave ripples,' is associated with thoughts that wander from the present situation. This activity begins in the hippocampus, a crucial brain region for memory formation and recall, and is linked to more vivid and less desirable thoughts. A better understanding of the relationship between sharp-wave ripples and these kinds of thoughts might be helpful for treating related conditions.
