Active exploration of novel environments is known to increase plasticity in animals, promoting long-term potentiation in the hippocampus and enhancing memory formation. These effects can occur during as well as after exploration. In humans novelty's effects on memory have been investigated with other methods, but never in an active exploration paradigm. We therefore investigated whether active ...

Thirty-five patients with trigeminal neuralgia underwent microvascular decompression. Complete remission was obtained in 33 patients, while one was fair and another unchanged postoperatively. The clinical and operative findings were reviewed, analyzing the direction of vascular compression of the trigeminal nerve and the distribution of pain in the peripheral regions. There were some weak corre...

Lipofibromatous hamartoma is a rare tumour-like condition involving the peripheral nerves, particularly the median nerve. It commonly affects the volar aspect of the hands, wrists and forearms of young adults. Most patients present either early with macrodactyly or later with a forearm mass lesion or symptoms consistent with compressive neuropathy of the involved nerve. The clinical and histomo...

BACKGROUND Vagus nerve stimulation (VNS) is currently used to treat refractory epilepsy and is being investigated as a potential therapy for a range of conditions, including heart failure, tinnitus, obesity and Alzheimer's disease. However, the invasive nature and expense limits the use of VNS in patient populations and hinders the exploration of the mechanisms involved. OBJECTIVE We investig...

introduction: median nerve (mn), one of terminal branches of brachial plexus, is commonly associated with several variations. this research aimed to review the literature related to the variations of mn from axillary region to cubital fossa. methods: we searched google scholar, science direct, springer, and pubmed electronic databases to compile reports related to the variation of mn published ...

objective(s):  the aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (esm) tube conduit in comparison with autograft. materials and methods: thirty adult male rats (250-300 g) were randomized into (1) esm conduit, (2) autograft, and (3) sham surgery groups. the eggs submerged in 5% acetic acid. the decalcifying membranes were cut into four pie...

Background: Malignant Peripheral Nerve Sheath Tumors (MPNSTs) are defined as malignant tumors arising from a peripheral nerve or displaying sheath differentiation. We report the first Korean case of MPNST ileum. Case Presentation: A 33-year-old female without family history neurofibromatosis type I complained lower abdominal pain. An abdomen computed tomography and enhanced magnetic resonance i...

Primary hyperparathyroidism is a common condition with surgery being the definitive treatment modality. Controversy exists over the extent of optimal neck exploration, whether unilateral or bilateral exploration should be performed, particularly since 85-90% of primary hyperparathyroidism results from single gland disease. Unilateral neck exploration is now considered to be adequate unless a de...
