Figure 5. Relationship between sleep spindle density and the negative R-F difference at retest.

Figure 5

The magnitude of the difference between memory for TBR and TBF negative scenes increased relative to the density of sleep spindle activity in Stage 2 sleep. This indicates that sleep spindles are associated with the discrimination of memory for salient items, specifically the preferential preservation of items cued TBR over those cued TBF.
