Laughter is a socially important behavior and its neural correlates are poorly understood. Depth electrode electrophysiological techniques offer a rare opportunity to both record and stimulate neural structures involved in emotion processing. This kind of direct electrophysiological investigation in humans is particularly determinant because laughter processing cannot be studied in animals.展开更多

We report on a patient with bilateral superior canal dehiscence syndrome who presented with unusual manifest ations including pulse synchronous vertical pendular nystagmus and Valsalva in duced, up and counterclockwise beating jerk nystagmus. These unusual symptoms m ay be a clue to a better understanding of the pathophysiology of superior canal dehiscence syndrome. Abnormal communication between the inner ears and the intra cranial space may explain the vertical pendular and pulse synchronous nystagmus , modulated by increased intracranial pressure.展开更多
