Coding of Speech Signals in the Human Auditory Nerve

"During surgery using a retro-sigmoid approach in the cerebellopontine angle (microvascular decompression, vestibular neurotomy, meningioma or schwannoma removal), near-field recording of human auditory nerve activity using a contact electrode is performed on patients with normal or impaired hearing threshold.~Each patient is explored preoperatively by hearing tests in noise and in silence. During the operation, stimuli are delivered in silence and in noise, under the same conditions as during the preoperative auditory exploration."
