Summary: Essential trigeminal neuralgia is the most common facial pain. In forms resistant to drug and disabling treatments, surgical treatment may be offered to the patient. The type of intervention will be conditioned by the presence or absence of a vasculo-nervous conflict objectified by MRI(Magnetic resonance imaging) Morphological MRI with contrast injection does not always allow an accurate assessmen...

Summary: In humans, surface electrophysiological recordings of the cochlear nerve in response to a sound stimulus provide information about the cochlear's ability to encode sound. Depending on the stimulus, the fine structure and temporal envelope of the signal will vary, allowing us to determine its characteristics. By phenotyping patients before surgery using subjective and objective audiometric tests, i...

Summary: The fine evaluation of the function of auditory neurons in silence and in noise in humans is difficult, if not impossible, to date with the conventional methods available. That is why in certain situations, the hearing aids of patient with hearing loss fail, especially in the presence of noise. In this study the investigators aim at investigating the global spontaneous and sound evoked human audit...
