Cerebral Vasodilator Nerves and Their Pathway From the Medulla Oblongata

Observations on the Extrinsic Neural Control of Cerebral Blood Flow in the Baboon

“…We have confirmed the observations of Chorobski and Penfield (46) and of Forbes et al (37) that the facial nerve transmits cerebral vasodilator activity. Section of the facial nerve with the vagi intact, however, causes little change in the vascular response to COo, and we have interpreted this as suggesting that other important efferent vasodilator pathways exist, possibly in other cranial nerves, which can still be controlled by afferent activity in the vagus or aortic nerves.…”

Histological and Functional Studies on the Nitroxidergic Nerve Innervating Monkey Cerebral, Mesenteric and Temporal Arteries

“…When examined in a section counter stained with cresyl violet, over 95% of the ganglionic neurons were stained positively in the dog pterygopalatine ganglion, whereas about 50% of the neuronal cell bodies were observed in the monkey ganglion. The monkey pterygopalatine ganglion reportedly contains a mixture of large and small myelinated as well as small unmyelinated fibers running in various directions (23). In the present study, large and small neurons seen in the ganglion were positively stained with NOS (Fig.…”

Cerebrovascular projections from the sphenopalatine and otic ganglia to the middle cerebral artery of the cat.

“…23 It is unlikely that the tracer seen in SPG and otic ganglia has a transsynaptic origin; intemalization of WGA-HRP conjugate by neurons seems to peak at 3-24 hours 23 and subsequent retrograde transport occurs at about 108 mm/day. 26 The occasional neuronally-shaped WGA-IR cells seen in the adventitia of the ipsilateral rete may correspond to the neuronal cell bodies seen along intracranial vessels by Chorobski and Penfield, 1 Borodula and Pletchkova, 27 Vasquez and Purves, 28 and Cervos-Navarro and Artigas. 29 It is known that the SPG provides postganglionic VIP-containing fibers to the nasal mucosa in cats;…”
