The , as the name indicates, is mainly composed of the so called giant neuronal cells.
This nucleus has been known to innervate the caudal
Hypoglossal Nucleus , and responds to
Glutamateric stimuli.
The gigantocellular nucleus excites the hypoglossal nucleus, and can play a role in the actions of the said nerve Yang, CC et al. Excitatory innervation of caudal hypoglossal nucleus from nucleus reticularis gigantocellularis in the rat. Neuroscience. 1995 Mar;65(2):365-74..
This nucleus receives connections from the
Periaqueductal Gray , the
Paraventricular Hypothalamic Nucleus ,
Central Nucleus Of The Amygdala ,
Lateral Hypothalamic Area , and
Parvocellular Reticular Nucleus .
Retrograde studies have shown that the deep mesencephalic reticular formation and
Oral Pontine Reticular Nucleus project to the
Nucleus Gigantocellularis .
The dorsal rostral section of the nucleus reticularis gigantocellularis is also involved mediating in
Expiration (or out-breathing) along with the
Parvocellular Nucleus .
