Thyrotropin-releasing hormone stimulates perinatal rat respiration in vitro.

In the present study, we test whether thyrotropin-releasing hormone (TRH) stimulates respiratory frequency in perinatal rats by acting at regions of the medulla responsible for respiratory rhythmogenesis, the pre-Bötzinger complex. We also test whether TRH stimulates respiration in the fetal rat at a time shortly after the inception of respiratory… CONTINUE READING
