Axons from the posterior hypothalamus descend through the mesencephalic and pontine reticular formations.

Pontine respiratory group (pneumotaxic center)

Granule cells receive excitatory input from mossy fibers originating from pontine nuclei.

Pontine cistern (Prepontine cistern or cisterna pontis).

The pneumotaxic center, also known as the pontine respiratory group (PRG), is a network of neurons in the rostral dorsal lateral pons.

The chief sensory nucleus (or "pontine nucleus" or "main sensory nucleus" or "primary nucleus" or "principle nucleus")

The rubrospinal tract and medullary reticulospinal tract biased flexion outweighs the medial and lateral vestibulospinal and pontine reticulospinal tract biased extension in the upper extremities.

The receptor is also widely distributed in the brain, including in the cortex, anterior olfactory nucleus, lateral septum, hypothalamus, hippocampus, amygdala, central gray, pontine nuclei, interpeduncular nucleus, substantia nigra, raphe complex, locus coeruleus, and spinal cord.
