Luke Remage-Healey

Post Doctoral Researcher, Department of Physiological Science and Laboratory of Neuroendocrinology, Brain Research Institute, UCLA.

Principle Research Interests:

The songbird brain has a widespread capacity for synthesizing steroid hormones independent of 'traditional' endocrine glands in the periphery. I am testing whether the production of steroids in adult zebra finch brain occurs in a rapid, minute-by-minute manner, and how local neurosteroid production relates to the expression of behavior.
