“…They concluded that the BD component DN1 measured at the vertex is mainly due to the contralateral inhibition of the lemniscal field potentials that result from the discharge activity of IE-cells in the LSO. Additionally, at the level of the SOC, Ungan and Yagcioglu (2002) demonstrated a bilateral asymmetry of the BD showing a stronger response to contralateral leading stimuli. This study strongly supports the hypothesis that the IE-cells in the LSO are the main BD generators and validates the IEmodel of binaural interaction.…”

“…In a seminal paper, Ungan and Yagcioglu (2002) simultaneously measured BDs from a vertex electrode and a deep electrode in the LSO and the lateral lemniscus (LL) in cat. DN1 amplitude and latency as function of the ITD corresponded with the field potential measured at the level of the LL.…”

“…The dependence of binaural difference potentials on the ITD has been analyzed in guinea pig (Dobie and Berlin, 1979;Goksoy et al, 2005), cat (Sontheimer et al, 1985;Ungan et al, 1997Ungan et al, , 2002 and humans (Wrege and Starr, 1981;Gerull and Mrowinski, 1984;Kelly-Ballweber and Dobie, 1984;Furst et al, 1985Furst et al, , 1990Jones and Van der Poel, 1990;McPherson and Starr, 1995;Polyakov and Pratt, 1996;Pratt et al, 1997;Brantberg et al, 1999;Riedel and Kollmeier, 2002a;Delb, 2003;Riedel and Kollmeier, 2003;Furst et al, 2004). The results of these studies are partially conflicting and were often interpreted against the background of the model by Jeffress (1948), the prevailing paradigm for azimuthal sound localization for now more than half a century.…”

“…The depth of the LSO was identified by the maximum evoked response. In addition, the binaural interaction component was evaluated to determine when the sum of right ear or left ear stimulation was different than the effect of binaural stimulation (see Finlayson and Caspary 1989;Wada and Starr 1989;Ungan and Yagcioglu 2002).…”

The functional consequences of selectively lesioning the lateral olivocochlear efferent system in guinea pigs were studied. The lateral superior olive (LSO) contains the cell bodies of lateral olivocochlear neurons. Melittin, a cytotoxic chemical, was injected into the brain stem using stereotaxic coordinates and near-field evoked potentials to target the LSO. Brain stem histology revealed discrete damage to the LSO following the injections. Functional consequences of this damage were reflected in depressed amplitude of the compound action potential of the eighth nerve (CAP) following the lesion. Threshold sensitivity and N1 latencies were relatively unchanged. Onset adaptation of the cubic distortion product otoacoustic emission (DPOAE) was evident, suggesting a reasonably intact medial efferent system. The present results provide the first report of functional changes induced by isolated manipulation of the lateral efferent pathway. They also confirm the suggestion that changes in single-unit auditory nerve activity after cutting the olivocochlear bundle are probably a consequence of disrupting the more lateral of the two olivocochlear efferent pathways.

“…The occurrence of wave 3 correlates with the integrity of the MNTB or its output (Wada and Starr, 1989, 1983; Jalabi et al, 2013) although Boettcher (2002) suggested that it is based on the activity of the cochlear nucleus. Wave 4 in the gerbil and cat and wave 5 in humans are attributed to more central stages of the auditory pathway already representing binaural cues like neurons in the medial superior olive (MSO) and the lateral superior olive (LSO) and fibers from the superior olivary complex (SOC) to the lateral lemniscus (LL; Boettcher, 2002; Riedel and Kollmeier, 2002; Ungan and Yagcioglu 2002; Grothe et al, 2010). In humans (Riedel and Kollmeier, 2002), cats (Ungan et al, 1997; Ungan and Yagcioglu 2002) and rodents (Goksoy et al, 2005), a specific binaural interaction component (BIC) of the ABR has been observed.…”

Aging effects on the binaural interaction component of the auditory brainstem response in the Mongolian gerbil: Effects of interaural time and level differences

The effect of interaural time difference (ITD) and interaural level difference (ILD) on wave 4 of the binaural and summed monaural auditory brainstem responses (ABRs) as well as on the DN1 component of the binaural interaction component (BIC) of the ABR in young and old Mongolian gerbils (Meriones unguiculatus) was investigated. Measurements were made at a fixed sound pressure level (SPL) and a fixed level above visually detected ABR threshold to compensate for individual hearing threshold differences. In both stimulation modes (fixed SPL and fixed level above visually detected ABR threshold) an effect of ITD on the latency and the amplitude of wave 4 as well as of the BIC was observed. With increasing absolute ITD values BIC latencies were increased and amplitudes were decreased. ILD had a much smaller effect on these measures. Old animals showed a reduced amplitude of the DN1 component. This difference was due to a smaller wave 4 in the summed monaural ABRs of old animals compared to young animals whereas wave 4 in the binaural-evoked ABR showed no age-related difference. In old animals the small amplitude of the DN1 component was correlated with small binaural-evoked wave 1 and wave 3 amplitudes. This suggests that the reduced peripheral input affects central binaural processing which is reflected in the BIC.
