Corrigendum: Postoperative cognitive dysfunction: spotlight on light, circadian rhythms, and sleep(Front. Neurosci., (2024), 18, (1390216), 10.3389/fnins.2024.1390216)

In the published article, there was an error. A paragraph from Section 2.2 was mistakenly duplicated in Section 2.1. Section 2.1, The circadian system, paragraph 3 previously stated: “Clock genes, particularly the PER2 gene, have also been associated with the homeostatic process of sleep. A common variant in PER2 was shown to be associated with a 20-min reduction in slow wave sleep, which is a marker of sleep homeostasis (Chang et al., 2016). Those with a polymorphism in the PER3 clock gene (PER3(5/5)) tend to be morning types and exhibit more rapid build-up of sleep pressure during sleep deprivation. These studies show the close link between clock genes and the sleep–wake cycle.” This duplicate paragraph has now been removed from Section 2.1. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
