This report summarizes recent neuropharmacological data at the IHC afferent/efferent
synaptic complex: the type of Glu receptors and transporter involved and the modulation of
this fast synaptic transmission by the lateral efferents. Neuropharmacological data were
obtained by coupling the recording of cochlear potentials and single unit of the auditory
nerve with intra-cochlear applications of drugs (multi-barrel pipette). We also describe the
IHC afferent/efferent functioning in pathological conditions. After acoustic trauma or …
