The effects of somatostatin microinjections into the solitary tract nucleus on Hering–Breuer reflex

In the paper, the data concerning the effects of somatostatin microinjections into the solitary tract nucleus on Hering–Breuer reflex are presented. We found a stimulatory effect of somatostatin on the reflex by an increase of normalized expiratory duration. Thus, modulation of Hering–Breuer reflex is appeared to be a possible mechanism of somatostatin action at the level of dorsal respiratory group.
