Study Summary

Prospective within-subject study of dexmedetomidine sedation paired with CLAS conditions in repeated blocks. Intervention will consist of CLAS in-phase with EEG slow waves. Anti-phase stimulation will serve as an active control while sham stimulation will serve as a passive control.

Primary Outcome

EEG slow waves activity (power) relative to the timing of the stimulation. Values are log-transformed All participants serve in the same arm but experience both sham and in-phase blocks.

  • RADIATION MRI
  • DIAGNOSTIC_TEST Quantitative Sensory Testing (QST)
  • DIAGNOSTIC_TEST Home sleep study
  • OTHER Acoustic stimulation (65db) up-slope of EEG with QST
