Study of the Role of Top-down Processes in Neuronal Reorganization and Recovery From Sensory Loss: an Exploratory Behavioral and Electroencephalographic Study in Cochlear-supported Deaf Patients

NCT07500909 · Status: NOT_YET_RECRUITING · Type: OBSERVATIONAL · Enrollment: 90

Last updated 2026-03-30

No results posted yet for this study

Summary

This study posits that central top-down processes (attention, inhibition), marked by alpha oscillations in EEG, play a key role. Understanding the evolution of these neuronal signatures and their link to pre-implantation visual dependence could allow the identification of biomarkers predictive of the success of auditory rehabilitation.

Conditions

  • Deafness, Bilateral

Interventions

OTHER

neurophysiological assessment

Electroencephalography and eye tracking

BEHAVIORAL

Cognitive, behavioral and quality of life assessment

Cognitive anfd behavioral assessment : Speech recognition test in silence (MBAA) and in noise, verbal working memory task with distractors, Trail Making Test and MoCA test. Quality of lige assessment : This questionnaire is a set of scales concerning patients' hearing abilities, experience, and listening skills in different situations. For each question, the patient must answer by choosing a number between 1 (not at all) and 10 (perfectly).
