“…The neural processing of repetitive FM sweeps in the human auditory cortex appears to differ from that of repetitive pure tones. Previous MEG studies using a two-tone adaptation paradigm supported our results by demonstrating that auditory evoked fields elicited by subsequent FM sweeps were larger when the preceding and subsequent FM sweeps were identical than when they had opposite FM directions; however, this effect was not observed in repetitive complex tones (Heinemann et al, 2010 , 2011 ). These findings were consistent with our results demonstrating maximal normalized N1m source strengths elicited by four repetitive identical FM sweeps in the “Identical” sequence.…”

“…Positron emission tomography (Zatorre and Belin, 2001 ) and functional MRI (Jamison et al, 2006 ) studies demonstrated that the right hemisphere plays a dominant role in spectral processing. Previous MEG studies (Heinemann et al, 2011 ; Okamoto and Kakigi, 2015 ) also revealed that the N1m responses elicited by FM sweeps were larger in the right than in the left hemisphere. The right hemispheric dominance for FM sweep processing observed in the present study is also consistent with previous findings demonstrating that auditory cortex lesions in the right hemisphere caused severe impairments in detecting the frequency modulation of test sounds, whereas lesions in the left did not cause such an impairment in animals (Wetzel et al, 1998 ; Rybalko et al, 2006 ) or humans (Johnsrude et al, 2000 ).…”

In our daily life, we are successively exposed to frequency-modulated (FM) sounds that play an important role in speech and species-specific communication. Previous studies demonstrated that repetitive exposure to identical pure tones resulted in decreased neural activity. However, the effects of repetitively presented FM sounds on neural activity in the human auditory cortex remain unclear. In the present study, we used magnetoencephalography to investigate auditory evoked N1m responses elicited by four successive temporally repeated and superimposed FM sweeps in three sequences: (1) four FM sweeps were identical, (2) four FM sweeps had the same FM direction and rate, but different carrier frequencies, (3) four FM sweeps differed with respect to the FM rate and/or direction and their carrier frequencies. In contrast to our expectations, the results obtained demonstrated that N1m responses were maximal when the four FM sweeps were identical and minimal when they were distinct. These results suggest that the neural processing of repetitive FM sweeps in the human auditory cortex may differ from that of repetitive pure tones.

“…This scenario might be in part due to an increased BOLD response for repeated stimuli, a phenomenon termed repetition enhancement (RE) (Segaert et al, 2013;Müller et al, 2013). Although the factors that determine a suppression or an increase of neuronal response to repeated stimulation have not yet been fully understood, RE has been repeatedly documented across sensory modalities (e.g., Doehrmann et al, 2010;Heinemann et al, 2011), and also using fMRI-adaptation auditory paradigms in the human IC (Chandrasekaran et al, 2012). Additionally, earlier magnetoencephalographic recordings have shown auditory RE effects for repeated sounds delivered at fast presentation rate (Loveless et al, 1989(Loveless et al, , 1996, similarly to the stimulus timing we employed our design.…”

Involvement of the human midbrain and thalamus in auditory deviance detection

Prompt detection of unexpected changes in the sensory environment is critical for survival. In the auditory domain, the occurrence of a rare stimulus triggers a cascade of neurophysiological events spanning over multiple timescales. Besides the role of the mismatch negativity (MMN), whose cortical generators are located in supratemporal areas, cumulative evidence suggests that violations of auditory regularities can be detected earlier and lower in the auditory hierarchy. Recent human scalp recordings have shown signatures of auditory mismatch responses at shorter latencies than those of the MMN. Moreover, animal single-unit recordings have demonstrated that rare stimulus changes cause a release from stimulusspecific adaptation in neurons of the primary auditory cortex, the medial geniculate body (MGB), and the inferior colliculus (IC). Although these data suggest that change detection is a pervasive property of the auditory system which may reside upstream cortical sites, direct evidence for the involvement of subcortical stages in the human auditory novelty system is lacking. Using eventrelated functional magnetic resonance imaging during a frequency oddball paradigm, we here report that auditory deviance detection occurs in the MGB and the IC of healthy human participants. By implementing a random condition controlling for neural refractoriness effects, we show that auditory change detection in these subcortical stations involves the encoding of statistical regularities from the acoustic input. These results provide the first direct evidence of the existence of multiple mismatch detectors nested at different levels along the human ascending auditory pathway.

“…Isochrony did not have an effect in our experiment in affecting the population response to the 200 ms stimuli. There is some evidence that at least two different processes can affect neuronal responses to isochronous stimuli: repetition‐following (Wang & Scheich, ) or an increase in baseline activity (Heinemann et al ., ; Keceli et al ., ). How can our finding of no main effect of isochrony be reconciled with evidence that modulation rate (Kilgard & Merzenich, ) and repetition time (Phillips et al ., ; Bendor & Wang, ; Dong et al ., ; Ma et al ., ; Recasens et al ., ) are encoded in the auditory cortex and can affect neuronal activity?…”

Auditory perception is improved when stimuli are predictable, and this effect is evident in a modulation of the activity of neurons in the auditory cortex as shown previously. Human listeners can better predict the presence of duration deviants embedded in stimulus streams with fixed interonset interval (isochrony) and repeated duration pattern (regularity), and neurons in the auditory cortex of macaque monkeys have stronger sustained responses in the 60-140 ms post-stimulus time window under these conditions. Subsequently, the question has arisen whether isochrony or regularity in the sensory input contributed to the enhancement of the neuronal and behavioural responses. Therefore, we varied the two factors isochrony and regularity independently and measured the ability of human subjects to detect deviants embedded in these sequences as well as measuring the responses of neurons the primary auditory cortex of macaque monkeys during presentations of the sequences. The performance of humans in detecting deviants was significantly increased by regularity. Isochrony enhanced detection only in the presence of the regularity cue. In monkeys, regularity increased the sustained component of neuronal tone responses in auditory cortex while isochrony had no consistent effect. Although both regularity and isochrony can be considered as parameters that would make a sequence of sounds more predictable, our results from the human and monkey experiments converge in that regularity has a greater influence on behavioural performance and neuronal responses.
