Averaging sleep spindle occurrence in dogs predicts learning performance better than single measures

Abstract Although a positive link between sleep spindle occurrence and measures of post-sleep recall (learning success) is often reported for humans and replicated across species, the test–retest reliability of the effect is sometimes questioned. The largest to date study could not confirm the assoc...
