Neuronal Networks Regulating Arousals to Apnea and Pain

       We conduct behavioral, biochemical, and electrophysiological studies in mouse models of apnea and pain, using novel genetic tools that can help selectively manipulate and record neural circuits involved in regulating neurobehavioral processes such as Sleep, Arousal, Pain, Breathing, and Sleep Homeostasis.

Tools:
  • Optogenetics
  • Pharmacogenetics
  • Recording population and single-cell calcium dynamics- a surrogate for neuronal activity
  • Comprehensive recordings of sleep, respiration, and body temperature in mouse models.
