“…Several studies have measured evoked cochlear responses to examine cochlear function in selective attention. In cats, the amplitude of the auditory evoked potential at the round window was reduced during visual attention tasks (Oatman, 1976;Glenn and Oatman, 1977). In human subjects, Puel et al (1988); Meric and Collet, (1992a) and Froehlich et al (1990) showed that evoked otoacoustic emissions from the outer hair cells in the cochlea were reduced when observers were engaged in a 0378-5955/$ -see front matter Ó 2008 Elsevier B.V.

“…Indeed, responses of neurons recorded in the cochlear nucleus of awake cats were found to change with the direction of visual attention~Hernandez-Peòn, Scherrer, & Jouvet, 1956!.

Influence of focused auditory attention on cochlear activity in humans

The mammalian auditory system contains descending pathways that originate in the cortex and relay at various intermediate levels before reaching the peripheral sensory organ of Corti. The last link in this chain consists of the olivocochlear bundle. The activity of this bundle can be measured through otoacoustic emissions, which are acoustic signatures of the cochlear biomechanical activity. In the present study, it was hypothesized that frequency-specific activation of the olivocochlear bundle in the contralateral ear would show up as frequency-specific variations in otoacoustic emission amplitude in the ipsilateral ear. Two groups of young adult subjects participated in this experiment. Evoked otoacoustic emissions were recorded in the ipsilateral ear at two test frequencies (1 and 2 kHz). Subjects had to detect probe tones at a given frequency in background noise in the contralateral ear. Larger efferent activation was measured at test frequencies on which attention is focused. This result provides evidence for an influence of attention on the auditory periphery via descending projections.

“…modalities are presented, one of which has to be attended. In fact, in the 1970s, a series of animal studies conducted by co-workers~Oatman, 1971, 1976;Oatman & Anderson, 1977Glenn & Oatman, 1977! showed clear attention effects on brain stem potentials in a bimodal paradigm, when attention was directed to or away from the visual modality.…”

Early attention effects in human auditory‐evoked potentials

A fundamental question in attention theory concerns the earliest processing stages that can be modulated by selective attention. A series of experiments is reported in which very early attention effects are found under specific conditions in the frequency-following potential (FFP), a brain stem response to low-frequency tone stimuli. In two experiments, stimuli of two different modalities were applied, and attention directed to one of the modalities. In two further experiments, only auditory stimuli were presented. In the first of these last two experiments, a dichotic paradigm with sustained attention to one ear was used, in the second a monotic paired-stimuli paradigm was used, in which the first stimulus served as reference for the second one. Only in the last experiment significant attention effects were found in the latency, but not in the amplitude of the FFP. The results show that a very early attention effect on the latency of the FFP can be demonstrated, but only under highly specific conditions. The size and preconditions of the attention effect suggest that it reflects subtle intramodal tuning mechanisms in the cochlea or in the lower brain stem.
