A Salivation Abnormality with Trigeminal Nerve Dysfunction in Dogs

Effects of Trigeminal Nerve Dysfunction in Various Types of Headaches.

Headaches are one of the most common ailments in modern society, leading to severe diminishing of general activities and they result in significant impact on the patient's quality of life. Blink reflex is an objective neurophysiological method for determining the status of the trigeminal system, facial nerve and the lateral part of medulla oblongata. The aim of this study was to examine the con...

Modification of a visceral response, salivation in thirsty dogs, by instrumental training with water reward.

Thirsty dogs rewarded by water for bursts of spontaneous salivation showed progressive increases in salivation, while other dogs, rewarded for brief periods without salivation, showed progressive decreases. No obvious motor responses were involved, but dogs rewarded for decreasing salivation appeared more drowsy than those rewarded for increasing it. Implications for learning theory and psychos...

Ancient Schwannoma of the Trigeminal Nerve Mimicking High Grade Lesion

  Ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. A seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. Imaging findings were suggestive of left temporal high grade lesion. During surgery there was well...

trigeminal pain and its distribution in different trigeminal nerve branches

Lipoma of trigeminal nerve in a patient with severe trigeminal neuralgia.

T1 coronal images show homogenous hyperintense lesion involving the right trigeminal nerve root (white arrows) in A and B and Meckel’s cave (white arrow) in C as compared to normal left trigeminal nerve (black arrows) and Meckel’s cave (yellow arrow). Axial T1 image also demonstrates the involvement ofmandibular division in foramen ovale (white arrow) as compared to normal on left side (orange ...
