Over the right parietal hemisphere, the interaction between group and laterality was highly significant ( F (1,30) = 10.93, p = 0.002) for relative changes in fast spindle activity (13.0–15.0 Hz) from odor off- to odor on-periods.

Changes in spindle density were also higher after odor presentation compared with odorless vehicle presentation for frontal slow spindles (odor presentation: 108.74 ± 5.27%, odorless vehicle presentation: 91.66 ± 5.27%; F (1,28) = 5.25, p = 0.03) and showed a statistical trend for parietal fast spindles (odor re-presentation: 142.40 ± 21.18%, odorless vehicle presentation: 88.31 ± 21.98%; F (1,25) = 3.14, p = 0.09).
