Research interests

At the Centre for Neuroendocrinology, our research focuses on understanding how the excitability of corticotropin-releasing hormone (CRH) neurons is regulated. CRH neurons are activated in response to stress and are responsible for controlling the levels of stress hormones in the body.

We are particularly interested in determining how changes in synaptic inputs and dendritic excitability regulate CRH neuron activity and function.

Clinical conditions

  • Stress
  • Depression
