We searched PubMed for “HPA axis modeling” and, as a result, identified 56 articles. Given the fast SNG-1153 of the field, we selected those that were published after 2000. Then, we read the abstracts of the remaining papers and narrowed the articles to those that had a simulation model of the HPA axis. Finally, we tracked additional articles based on citations in the sample. Our final sample included 14 articles [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36] and [37]. These 14 reports developed mathematical models of the HPA axis to show how an HPA axis might become impaired [25], [31] and [37], to offer treatment for normalizing HPA axis [29], to show the role of ultradian oscillation in response to stress and in homeostasis [34] and [35], and to replicate the ultradian and/or circadian oscillations observed in the cortisol and ACTH concentrations [24], [25], [26], [27], [28], [30], [32], [33] and [36].
