Diagonal band neurons may mediate arterial baroreceptor input to hypothalamic vasopressin-secreting neurons

Neurosci Lett. 1986 Apr 11;65(2):214-8. doi: 10.1016/0304-3940(86)90307-1.

Abstract

Diagonal band of Broca (DBB) neurons projecting to the hypothalamic supraoptic neurosecretory neurons were antidromically identified in pentobarbital-anesthetized male Long-Evans rats. Six of 12 DBB neurons tested for response to baroreceptor activation showed a consistent increase in firing. We propose that the established baroreceptor-induced inhibition of hypothalamic vasopressinergic neurons is mediated through DBB neurons.
