“…Based on previous findings for pitch (Takegata & Morotomi, 1999), periodicity was expected to enhance the MMN response for the controls given that fixed inter-stimulus timing adds a further element of predictability. Based on the timing hypothesis, we predicted that this effect would be reduced or absent in the cerebellar patients, reflecting an impaired ability to utilize the temporal regularity.…”

“…In a study of healthy individuals, Takegata and Morotomi (1999) reported an enhanced MMN amplitude to a pitch deviant when the interval separating successive stimuli was fixed compared to when this interval was variable. Thus, the sensory prediction was not only of a stimulus of a particular pitch, but also of one that would occur at a particular time.…”

“…Within the field of EP research, one of the most established ideas about temporal information processing comes from research extracting the so-called mismatch negativity, or MMN (Takegata et al, 2001;Jaramillo et al, 2000;Takegata and Morotomi, 1999;Alain et al, 1999a,b). MMN is, like the EP P3 component, typically elicited by infrequently occurring, deviant, stimuli.…”

“…For example, whether single repeated tones in periodic versus aperiodic sequences elicit a smaller N1-P2 complex of the AEP is still unclear (Nelson et al, 1969;Rothman et al, 1970;Nelson and Lassman, 1977). Similarly, periodicity in an AEP oddball paradigm can yield N1 decrements (Harada et al, 2005), P50 decrements (Moberget et al, 2008), and contradictory effects on preattentive deviance detection (Takegata and Morotomi, 1999;Schwartze et al, 2011). Divergences might arise from using inappropriate stimulation paradigms; because AEP repetition effects occur rapidly, using different stimuli with a variable number of repetitions might prove more instructive (e.g., roving standard paradigm) (Baldeweg et al, 2004;Cowan et al, 1993).…”

Neural activity in the auditory system decreases with repeated stimulation, matching stimulus probability in multiple timescales. This phenomenon, known as stimulus-specific adaptation, is interpreted as a neural mechanism of regularity encoding aiding auditory object formation. However, despite the overwhelming literature covering recordings from single-cell to scalp auditory-evoked potential (AEP), stimulation timing has received little interest. Here we investigated whether timing predictability enhances the experience-dependent modulation of neural activity associated with stimulus probability encoding. We used human electrophysiological recordings in healthy participants who were exposed to passive listening of sound sequences. Pure tones of different frequencies were delivered in successive trains of a variable number of repetitions, enabling the study of sequential repetition effects in the AEP. In the predictable timing condition, tones were delivered with isochronous interstimulus intervals; in the unpredictable timing condition, interstimulus intervals varied randomly. Our results show that unpredictable stimulus timing abolishes the early part of the repetition positivity, an AEP indexing auditory sensory memory trace formation, while leaving the later part (ϳϾ200 ms) unaffected. This suggests that timing predictability aids the propagation of repetition effects upstream the auditory pathway, most likely from association auditory cortex (including the planum temporale) toward primary auditory cortex (Heschl's gyrus) and beyond, as judged by the timing of AEP latencies. This outcome calls for attention to stimulation timing in future experiments regarding sensory memory trace formation in AEP measures and stimulus probability encoding in animal models.
