Synapse formation in the rat superior cervical ganglion has been investigated electrophysiologically and at the ultrastructural level. Preganglionic axons first enter the superior cervical ganglion between days 12 and 13 of gestation (E12 to E13), and on E13 a postganglionic response can be evoked

Using a computer-assisted infrared optometer with a pupillograph, we tried to obtain basic understanding of accommodative disturbance and its by investigating tonic (dark focus) level of accommodation and quasi-static accommodative response. In normal volunteers in whom either visual fatigue,

Migraine headache is triggered by and associated with a variety of hormonal, emotional, nutritional, and physiological changes. The perception of migraine headache is formed when nociceptive signals originating in the meninges are conveyed to the somatosensory cortex through the trigeminal ganglion,

A 44-year-old man with a documented 12-year history of progressive sensorineural hearing loss developed a generalized tonic-clonic seizure followed by a visual field deficit and apraxia. Six months later he developed a peripheral neuropathy and muscle fatigue followed by a slowly progressive aphasia

Common understanding of residual hip dysplasia of the adult characterizes it as a uniform, anterolateral insufficiency of femoral head coverage; the proximal femur may or may not have increased valgus and antetorsion. This view is reflected by the parameters used for quantification but also by the

Background: Although gangliocytic paraganglioma (GP) is considered a rare benign neuroendocrine tumor, cases of mortality have been reported. Occasionally, GP is misdiagnosed as neuroendocrine tumor G1, which is associated with a poorer prognosis than GP. To avoid such misdiagnoses, it is important

BACKGROUND
Pheochromocytoma (PHEO) is a rare tumor of the adrenal medulla and sympathetic ganglion that produces the catecholamines norepinephrine and epinephrine. Traditionally, approximately 10% of PHEOs were thought to be malignant, but recent developments in PHEO research have noted that

Recent work has shown that alterations in the dynamic atrioventricular (AV) nodal response to changes in heart rate can significantly modify AV nodal function. The present study was designed to evaluate the nature and potential importance of sympathetic regulation of the rate-dependent properties of

BACKGROUND
Herpes simplex virus type 1 infection usually causes a mild, self-limiting painful blistering around the mouth, with 20-40% of adults affected at some time. Primary infection usually occurs in childhood, after which the virus is thought to remain latent in the trigeminal ganglion.

Evidence for the existence of sympathetic vasodilator nerves in human skeletal muscle is controversial. Manoeuvres such as contralateral ischaemic handgripping to fatigue that cause vasoconstriction in the resting forearm evoke vasodilatation after local alpha-adrenergic receptor blockade, raising
