Brain: Ventral reticular nucleus
Latin	nucleus reticularis ventralis
NeuroNames	hier-730

The ventral reticular nucleus is a continuation of the parvocellular nucleus in the brainstem.

The ventral reticular nucleus has been shown to receive afferent projections from the dentate gyrus in rabbits ^[1].

The rostral portion of the ventral reticular nucleus has been shown to mediate inspiration along with a portion of the lateral reticular nucleus.
