It has been confirmed that some kinds of what are called memory strategies dramatically improve the performance of memory recall. However, there has been no direct research to examine changes in brain activity associated with the use of the method of loci within individuals. In the present study, using fMRI, we compared brain activations before and after instruction in the method of loci during...

SUBJECTS AND METHODS Forty-two patients with a mean age of 9 ± 0.8 years were selected from the Department of Orthodontics, University of Catania, Italy. These subjects...

Lingual thyroid (LT) is a rare developmental thyroid anomaly usually affecting. Although the exact pathogenesis of this ectopic, accessory thyroid tissue is not known, it generally originates from epithelial tissue of non-obliterated thyroglossal ductus.

introduction: laser surgery as an alternative for conventional surgical procedure has gained special attention. using carbon dioxide (co2) laser has some benefits like less post-operative pain, swelling and infection, decrease in risk of metastasis and edema, and less bleeding providing dry sites for surgery. case report: a 12 years old boy with lingual frenum with indication for excision was r...

BACKGROUND The aim of the study was to analyse intraoral neurophysiological changes in patients with unilateral lingual nerve lesions as well as patients with Burning Mouth Syndrome (BMS) by applying a standardized Quantitative Sensory Testing (QST) protocol. METHODS The study included patients suffering from a peripheral lesion of the lingual nerve (n = 4), from BMS (n = 5) and healthy contr...

BACKGROUND Pain and sensory changes due to lingual nerve injury are one of the most common alterations that follow surgical removal of third molar. They are usually transient but other less common complications, such as the atrophy of fungiform papillae, have an uncertain prognosis. CASE DESCRIPTION We report a case of a 34-year-old woman who presented a unilateral lingual atrophy of fungifor...

Disease agents that principally target the tongue are relatively rare. It seems that type of food and roughage play an important role to predispose the animals to lingual ulcers. During a period of four years different aspects of cattle lingual fossa ulcer were studied in a semi-industrial dairy farm in Tehran. The affected animals showed various stages of ulcer formation in their lingual fossa...
