Bergen Stress and Sleep Group, BSSG

Research methods

The research group has long experience with animal models, mostly rats, and use modern laboratory facilities which meet international standards and demands within animal research. This includes a large range of behavioral testing equipment, equipment for biochemical and histological analyses, neurophysiological laboratory measurements of EEG/EMG, telemetry and extracellular stimulation and recording.

 

EXPERIMENTAL METHODS
- used in animal studies     

  • Objective measures of sleep and waking function (EEG and EMG)
  • Objective measures of circadian rhythmicity
  • Forced Activity (automated running wheels)
  • Telemetry
  • Electrophysiology
  • Open field
  • Startle response
  • Elevated Plus Maze
  • Pavlovian and Instrumental Conditioning
  • Biochemical parameters
  • Molecular measures of brain function
  • Metabolic measures of energy intake and expenditure

 

 CLINICAL AND EXPERIMENTAL METHODS
 -used in human studies

  • Objective and subjective measures of sleep and waking function (EEG and EMG)
  • Objective and subjective measures of circadian rhythmicity
  • Biochemical parameters (saliva, blood samples)
  • Clinical interviews
  • Self-reported questionnaires
  • Stress-responsivity tests
  • Human centric lighting

 

The biochemical laboratory at the Faculty of Psychology (UoB) has a central role within the research activity of BSSG.
