Brown Laboratory

Research interests

Our research group principally uses electrophysiology and immunohistochemistry to determine how the brain controls birth, lactation, and cardiovascular function. Our main focus is on how oxytocin and vasopressin contribute to preterm labour, high blood pressure and heart problems.

Clinical conditions

  • Preterm labour
  • Preeclampsia
  • Hypertension
  • Myocardial infarction
