Outcome Measures

Primary Outcomes (1)

  • Sleep spindle rate

    Sleep spindles are prominent thalamocortical brain oscillations seen on EEG during sleep that have been mechanistically linked to sleep-dependent memory consolidation. The sleep spindle rate over the course of the nap will be assessed using an automated spindle detector applied to the collected EEG sleep data.

    90 minutes

Secondary Outcomes (1)

  • Memory consolidation

    90 minutes

Study Arms (2)

Auditory Stimulation

ACTIVE COMPARATOR

Quiet sounds are played during sleep

Other: Quiet Sounds

Sham Stimulation

SHAM COMPARATOR

Volume is set to zero.

Other: Sham sounds

Interventions

Quiet sounds are played during sleep

Auditory Stimulation

No sounds are played during sleep

Sham Stimulation
