SimThyr is a simulation program for the pituitary thyroid feedback control system. The software is based on a parametrically isomorphic model of thyroid homeostasis, and it aims at a better insight into the dynamics of thyrotropic feedback. Applications of this program cover research, including development of hypotheses, and education of students in biology and medicine, nurses and patients. Historically, SimThyr helped to expand our knowledge of thyroid homeostasis, as documented in multiple research papers.
