Abstract/Results: ABSTRACT:
We aimed at demonstrating that increasing the regularity in the acoustic background helps to back-propagate the encoding of its regularities upstream the auditory pathway. Specifically, we wanted to show that 1) the human auditory system was able to track stimulus repetition effects at brainstem level, only when precise timing information is available, and 2) that the beneficial effects of temporal regularity in back-propagating the encoding of the acoustic environment relies on the entrainment of neural oscillations to the rhythm of stimulation. The EEG of healthy subjects was recorded during passive listening of sounds presented at a constant or random pace. Results of experiment 1 showed that the auditory brainstem response showed repetition effects, (e.g., adapted to irrelevant information) that were stronger when stimuli occurred in regular compared to random timing. Results of experiment 2 confirmed that temporal predictability is critical to enhance regularity encoding. In fact, the span of adaptation of the N1 auditory evoked potential was larger for isochronous that for random timing. Moreover, the results disclosed a new component of the evoked potentials that is “emitted” when a stimulus is expected (as induced by its constant timing presentation) but nevertheless never occurs. Critically, we showed that this “emitted” response was related to larger Beta oscillations as a function of the Delta rhythm phase. We conclude that only when the content of stimulation is predictable, the auditory system is able to pre-activate memory traces to compare with future stimulation, and that this predictive activity is organized in time by entrained oscillations to the rhythms of the acoustic scene.

Abstract/Results: ABSTRACT:
How do we perceive the auditory world? This remains as a mystery, but recent research has suggesting that the
auditory system extracts regularities from the ongoing acoustic input to build up auditory object representations. In my
talk, I will discuss recent evidence obtained in our laboratory with the complex Auditory Brainstem Response (cABR),
the Middle Latency Response (MLR), Magnetoencephalography (MEG), and functional Magnetic Resonance Imaging
(fMRI) demonstrating that human regularity encoding, as demonstrated by deviance detection, occurs at latencies and in
neural networks comparable to those revealed in animal studies of single-neuron activity. Our results demonstrate that
the encoding of simple acoustic-feature regularities and detection of corresponding deviance, such as an infrequent
change in frequency or location, occur in the latency range of the MLR, in separate auditory cortical regions from those
generating the mismatch negativity (MMN) long-latency evoked potential, and even at the level of human auditory
brainstem. In contrast, violations of more complex regularities, such as those defined by the alternation of two different
tones or by feature conjunctions (i.e., frequency and location) fail to elicit MLR correlates but elicit sizable MMNs. Taken
together, these findings support the emerging view that regularity encoding, as revealed by deviance detection, is a
basic principle of the functional organization of the auditory system, one that it is organized in ascending levels of
complexity along the auditory pathway expanding from the brainstem up to higher-order areas of the cerebral cortex.

Abstract/Results: ABSTRACT:
Neural activity is reduced after the presentation of a repeated stimulus, a phenomenon known as repetition suppression (RS). In the auditory domain, this reduction has been reported in animal cortical and subcortical structures using single and multi–unit recordings and in the human auditory cortex as revealed by the modulation of the long– and middle–latency auditory evoked potentials to repeated sounds. However, before the auditory information arrives to the cortex, it is deeply processed in the auditory brainstem, which has the ability to encode context–dependent information. This study was set out to investigate whether RS is a phenomenon that occurs at the level of the auditory brainstem and if timing predictability of the input influences the brainstem response to the repetitive sounds. Here we recorded the auditory brainstem frequency–following response (FFR) to consonant–vowel stimuli (/wa/) in a six–talker babble background presented with two timing conditions. In the predictable timing, stimuli were delivered with isochronous stimulus onset–to–onset intervals (366ms) and in the unpredictable timing condition, onset–to–onset time varied randomly between 183 and 549 ms. Our results showed that as the number of stimulus repetitions increases, the auditory brainstem evoked response was suppressed. Furthermore, a reduction in the brainstem FFR was observed when the stimuli were presented with a predictable timing compared with the unpredictable one. These findings demonstrate that repetition suppression is a phenomenon that not only takes place in human auditory cortex, but also in the human auditory brainstem, and confirm that the response of the brainstem is sensitive to the timing of the auditory input.

Timing predictability enhances regularity encoding in the human subcortical auditory pathway
Publication year: 2016

Abstract/Results: ABSTRACT:
The encoding of temporal regularities is a critical property of the auditory system, as short-term neural representations of environmental statistics serve to auditory object formation and detection of potentially relevant novel stimuli. A putative neural mechanism underlying regularity encoding is repetition suppression, the reduction of neural activity to repeated stimulation. Although repetitive stimulation per se has shown to reduce auditory neural activity in animal cortical and subcortical levels and in the human cerebral cortex, other factors such as timing may influence the encoding of statistical regularities. This study was set out to investigate whether temporal predictability in the ongoing auditory input modulates repetition suppression in subcortical stages of the auditory processing hierarchy. Human auditory frequency-following responses (FFR) were recorded to a repeating consonant-vowel stimuli (/wa/) delivered in temporally predictable and unpredictable conditions. FFR amplitude was attenuated by repetition independently of temporal predictability, yet we observed an accentuated suppression when the incoming stimulation was temporally predictable. These findings support the view that regularity encoding spans across the auditory hierarchy and point to temporal predictability as a modulatory factor of regularity encoding in early stages of the auditory pathway.
