Réponses évoquées auditives à un clic monaural et à un clic binaural enregistrées au vertex et dans deux dérivations temporales; effet du décalage interaural

Abstract

The auditory-evoked responses have been recorded on 5 subjects by vertex, right temporal and left temporal electrodes simultaneously. 30 dB sensation level clicks were used as stimuli; one click was presented only to the right ear, or one click only to the left ear, or one click to the right ear and another click to the left ear with a variable interaural time difference in this latter case (0-150 ms). The N₁-P₂ amplitude variations and the N₁ and P₂ latency variations have been studied and compared to those observed in the perceived lateralizations of the sound source

Key Words:

• Electric response audiometry (ERA)
• Auditory-evoked responses
• Inter-hemispheric differences
• Interaural time delay
