Hering-Breuer reflex in conscious newborn rats: effects of changes in ambient temperature during hypoxia.


In a previous study in conscious normoxic newborn rats, we found that the strength of the Hering-Breuer reflex (HB reflex) was greater (188%) at high (36 degrees C) than at low (24 degrees C) ambient temperature (T(a); D. Merazzi and J. P. Mortola. Pediatr. Res. 45: 370-376, 1999). We now asked what the effect would be of changes in T(a) during hypoxia. Rat… (More)
