An excitatory amino acid, possibly L-glutamate, which probably acts as a neurotransmitter at the inner hair cell-afferent fiber synapses in the cochlea. In the present study, we have used an electrophysiological approach to investigate at this level the presence of a major type of excitatory amino acid receptor, namely the glutamatergic receptor for which(More)
BACKGROUND In the past decade, contralateral sound suppression of otoacoustic emissions has been extensively used to study the role of the medial olivocochlear efferent in humans. In most studies, the suppressive effect of contralateral sound stimulation was not greater than 2 to 4 dB. However, the relation between the degree of otoacoustic emission(More)
The present study was designed to investigate the early maturation of the brainstem regulation of the cochlear function in preterm neonates. Evoked otoacoustic emissions (EOAE) and their regulation via the medial olivocochlear efferent (MOC) reflex were investigated in a large population of preterm neonates and compared with full-term neonates and young(More)
