Structured Spindle-Band EEG Patterns Emerge for Declarative Odor Cues During Sleep

Decoding of declarative odor cueing from sleep spindle-band EEG surpassed non-declarative cueing, with strongest effects in central channels, but effects were modest and did not survive correction for multiple comparisons.

• Within-participant Riemannian-based classification of high-density EEG (fast and slow spindle bands, multiple time windows); sample size not reported in source.
• Largest decoding differences occurred over central channels for declarative cues, though no effect survived correction for multiple comparisons.
• Findings are preliminary; no external or cross-participant validation, and effect size/confidence intervals not available in abstract.
