Glossopharyngeal nerve (GL) transection in rats is known to markedly reduce gaping, a stereotypical aversive oromotor behavior, in response to intraorally delivered quinine. In this experiment we tested whether GL transection would reduce gaping in response to an otherwise palatable stimulus (sucrose) but conditioned to be aversive. Sprague-Dawley rats were implanted with intraoral cannulae. Fi...

Moebius syndrome is a rare, nonprogressive neurological disorder (prevalence is estimated to be 0.002% of births) characterized by unilateral or bilateral facial paralysis and defective extraocular eye movements secondary to congenital paresis of the facial (VII) and abducens (VI) cranial nerves. These classic features of the syndrome are often accompanied by hypoglossal (XII), trigeminal (V), ...

Glossopharyngeal neuralgia is a distinctive syndrome, named by Wilfred Harris. Investigation must exclude multiple sclerosis, and local compression, especially by tumours which require treatment. Dandy deserves credit for first indicating vascular compression of cranial nerve roots as a cause of cranial neuralgias, and Jannetta for establishing neurovascular decompression. Vascular compression ...

BACKGROUND We introduce a method of noninvasive topographical analysis of the neurovascular relationships of the glossopharyngeal nerve (CN IX) by three-dimensional (3D) visualization. Patients with glossopharyngeal neuralgia (GN) resulting from neurovascular compression (NVC) were studied. METHODS 15 patients with GN were prospectively examined with 3D visualization using high-resolution mag...

Taste receptors on the left and right sides of the anterior tongue are innervated by chorda tympani (CT) fibers, which carry taste information to the ipsilateral nucleus of the solitary tract (NST). Although the anterior tongue is essential for taste, patients with unilateral CT nerve damage often report no subjective change in their taste experience. The standing theory that explains the taste...

By the time these words appear in print, I understand that we shall have taken one more step, whatever that is, towards joining the European Community whatever that is. (We have trouble enough defining what we mean by a community even within Britain; I can't imagine it's going to be any easier, in European terms, even to perceive the community, let alone define it.) Anyway, before very long, pe...

Wheat germ agglutinin-horseradish peroxidase injected into the petrosal ganglion in rats was transported to the posterior tongue in the glossopharyngeal nerve. Labelled fibers innervated the ipsilateral foliate papilla only, but both ipsi-and contralateral sides of the single circumvallate papilla. Somatosensory fibers in the posterior tongue also were labelled. Label crossed transcellularly fr...

Objective – to summarize the various hypotheses regarding development of Trigeminal Neuralgia with a brief discussion about causes for its co-existence Glossopharyngeal Neuralgia, which has been seen infrequently. Summary background - Cranial nerve neuralgia is one most common pain syndromes attributed extreme (extremely) detrimental effects on middle age population who are more productive. The...
