One of the first symptoms of a heart attack can be pain in the teeth and/or jaws. In the case of a heart attack, the presence of pain in the teeth or jaws doesn't mean that there is any dental condition that needs to be treated, in the absence of any pre-existing dental condition. The experience of dentally related pain during a heart attack is a classical example of referred pain which is pain...

OBJECTIVE To describe a patient with facial onset sensory motor neuronopathy (FOSMN) syndrome associated with a heterozygous D90A mutation in superoxide dismutase (SOD1) gene. METHODS The patient underwent neurological and neurophysiologic examinations, including blink and jaw reflexes, sural nerve and skin biopsies, and analysis of TARDBP, FUS and C9ORF72 genes. RESULTS Neurological examin...

Axonal regeneration is one of the greatest challenges in severe injuries of peripheral nerve. To provide the bridge needed for regeneration, biological or synthetic tubular nerve constructs with aligned architecture have been developed. A key point for improving axonal regeneration is assessing the effects of substrate geometry on neuronal behavior. In the present study, we used an extracellula...

A study of the insect central nervous system (Rowell, 1964, 1969) required the impulse traffic in a connective to be resolved into that fraction propagating anteriorly and that propagating posteriorly, and to describe each fraction in terms of the amplitude and frequency of action potentials. The first requirement is usually met by cutting the nerve and recording independently from the two ends...

We report the case of a right-handed 67-year-old uremic woman with severe left carpal tunnel syndrome (CTS) in whom preoperative neurophysiologic data suggested that the thenar motor branch (TMB) of the median nerve ran an anomalous course that was confirmed during surgical release. The patient had undergone periodic hemodialysis for 10 years through a vascular graft at the left forearm. The pa...

Nerve action potentials recorded over the elbow after stimulation of the wrist were studied in patients with hand amyotrophy of different origin. In amyotrophic lateral sclerosis the amplitude of nerve action potentials does not change significantly even with extreme muscle wasting and loss of motor units.Studies of multisegmental afferent conduction velocities may demonstrate a strictly locali...

PURPOSE To non-invasively study the sensory nerve conduction of the caudal nerve of normal developing rats. METHODS Twenty normal Wistar male rats served as subjects. Caudal nerve conduction studies were performed at 60 days from birth and weekly at end of six consecutive weeks. The caudal nerve was stimulated distally and nerve potentials were recorded proximally on the animal's tail using c...

Although it is well known that cisplatin causes a sensory neuropathy, the primary site of involvement is not established. The clinical symptoms localized in a stocking-glove distribution may be explained by a length dependent neuronopathy or by a distal axonopathy. To study whether the whole neuron or the distal axon was primarily affected, we have carried out serial clinical and electrophysiol...

introduction: considering the antiepileptogenic effects of repeated transcranial magnetic stimulation (rtms), the effect of rtms applied during amygdala kindling on spontaneous activity of hippocampal ca1 pyramidal neurons was investigated. materials and methods: a tripolar electrode was inserted in basolateral amygdala of male wistar rats. after a recovery period, animals received daily kindli...
