title: Sleep and EEG spectra in rats recorded via telemetry during surgical recovery.
abstract: OBJECTIVE
  To determine sleep and EEG spectra in rats during surgical recovery.
  
  
  METHODS
  Sleep, activity, and EEG spectral power were examined in rats via telemetry on days 1, 2, 3, 7, 14, and 15 after implantation surgery.
  
  
  RESULTS
  NREM sleep and total sleep were increased on days 1 and 2 compared to later days. REM sleep was decreased on days 2 and 3 compared to days 14 and 15, and activity was decreased on days 1 and 2 compared to later days. EEG power (0.5-5 Hz for NREM and wakefulness, and 5.5-10 Hz for REM and wakefulness) was increased on days 1-3 compared to days 7, 14, and 15.
  
  
  CONCLUSIONS
  The results are discussed in terms of their implications for post-surgery stabilization of sleep and potential relevance for sleep after injury.
