One suggestion is that a function of encoding-related theta power may be to \u201ctag\u201d memories for subsequent processing during sleep. This study aimed to extend previous work on the relationships between sleep spindles, slow oscillation-spindle coupling, and task-related theta activity with a combined Deese-Roediger-McDermott (DRM) and nap paradigm. This allowed us to examine the influence of task- and sleep-related oscillatory activity on the recognition of both encoded list words and associative theme words. Thirty-three participants (29 females, mean age = 23.2 years) learned and recognised DRM lists separated by either a 2 h wake or sleep period. Mixed-effects modelling revealed the sleep condition endorsed more associative theme words and fewer list words in comparison to the wake group. Encoding-related theta power was also found to influence sleep spindle density, and this interaction was predictive of memory outcomes. The influence of encoding-related theta was specific to sleep spindle density, and did not appear to influence the strength of slow oscillation-spindle coupling as it relates to memory outcomes. The finding of interactions between wakeful and sleep oscillatory-related activity in promoting memory and learning has important implications for theoretical models of sleep-based memory consolidation.<\/jats:p>","DOI":"10.3389\/fnhum.2022.821191","type":"journal-article","created":{"date-parts":[[2022,5,9]],"date-time":"2022-05-09T04:41:01Z","timestamp":1652071261000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Theta Activity During Encoding Interacts With NREM Sleep Oscillations to Predict Memory Generalization"],"prefix":"10.3389","volume":"16","author":[{"given":"Tamara","family":"Gibson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zachariah R.","family":"Cross","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alex","family":"Chatburn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,5,9]]},"reference":[{"key":"B1","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1007\/BF00197314","article-title":"Simulation of daytime vigilance by the additive interaction of a homeostatic and a circadian process.","volume":"71","author":"Achermann","year":"1994","journal-title":"Biol.
