Significance We reveal the temporal dynamics and underlying neural sources of the process by which the brain discovers complex temporal patterns in rapidly unfolding sound sequences. We demonstrate that the auditory system, supported by a network of auditory cortical, hippocampal, and frontal sources, continually scans the environment, efficiently represents complex stimulus statistics, and rapidly (close to the bounds implied by an ideal observer model) responds to emergence of regular…

Sustained Pupil Responses Are Modulated by Predictability of Auditory Sequences
The findings suggest that the pupil response can be used to study the automatic extraction of regularities, and that the effects are most consistent with predictability helping the listener to efficiently process upcoming sounds.
The Cumulative Effects of Predictability on Synaptic Gain in the Auditory Processing Stream
This work establishes the oscillatory neural correlates of independent predictability manipulations in hierarchically distinct areas of the auditory processing stream and accurately explains the sensor-level sustained field amplitude, demonstrating that slow changes in synaptic efficacy, combined with sustained sensory input, can result in profound and sustained effects on neural responses to predictable sensory streams.
Direct brain recordings reveal continuous encoding of structure in random stimuli
This work addresses the role of transitional probabilities as an implicit structure supporting the encoding of a random auditory stream and reveals the involvement of a network outside of the auditory system, including hippocampal, frontal, and temporal regions.
Sustained pupil responses are modulated by predictability of auditory sequences
The findings suggest that the pupil response can be used to study the automatic extraction of regularities, and that the effects are most consistent with predictability helping the listener to efficiently process upcoming sounds.
Predictive cues for auditory stream formation in humans and monkeys
The results from the human and monkey experiments converge in that regularity has a greater influence on behavioural performance and neuronal responses compared with isochrony.
Top-down, contextual entrainment of neuronal oscillations in the auditory thalamocortical circuit
Significance Our results indicate that nonhuman primates detect complex repeating acoustic sequences in a continuous auditory stream, which is an important precursor for human speech learning and
Is predictability salient? A study of attentional capture by auditory patterns
In this series of behavioural and electroencephalography (EEG) experiments, we investigate the extent to which repeating patterns of sounds capture attention. Work in the visual domain has revealed
Neuronal phase consistency tracks dynamic changes in acoustic spectral regularity
It is found that the degree of oscillatory stimulus phase consistency (PC) in multiple neuronal‐frequency bands tracked spectral regularity, and this widespread reliable modulation in PC suggests that phase‐based modulations may be a general mechanism for tracking regularity in the auditory system and other sensory systems more generally.
Neural Signatures of the Processing of Temporal Patterns in Sound
The results suggest that neural synchronization and sustained activity levels are functionally linked: both are sensitive to regularities in sounds, however, neural synchronization might reflect a more sensory-driven response to regularity compared with sustained activity which may be influenced by attentional, contextual, or other experiential factors.


Auditory temporal edge detection in human auditory cortex
Outlier Responses Reflect Sensitivity to Statistical Structure in the Human Brain
The results demonstrate a very early neurophysiological marker of the brain's ability to implicitly encode complex statistical structure in the environment and suggest that this sensitivity provides a computational basis for the ability to make perceptual inferences in noisy environments and to make decisions in an uncertain world.
Multiple Time Scales of Adaptation in Auditory Cortex Neurons
It is proposed that a major function of SSA in A1 neurons is to encode auditory sensory memory on multiple time scales, a property that is crucial for processing of natural auditory scenes in cats and of speech and music in humans.
The neural circuitry of pre-attentive auditory change-detection: an fMRI study of pitch and duration mismatch negativity generators.
Using functional magnetic resonance imaging, it is shown that anatomically distinct networks of auditory cortices are activated as a function of the deviating acoustic feature--in this case, tone frequency and tone duration--strongly supporting the hypothesis that MMN generators in auditory cortex are feature dependent.
Efficient auditory coding
It is shown that, for natural sounds, the complete acoustic waveform can be represented efficiently with a nonlinear model based on a population spike code, which shows striking similarities to time-domain cochlear filter estimates, have a frequency-bandwidth dependence similar to that of auditory nerve fibres, and yield significantly greater coding efficiency than conventional signal representations.

“Change Deafness” Arising from Inter-feature Masking within a Single Auditory Object
The results reveal a form of “change deafness,” in that listeners often fail to detect changes in the frequency pattern when that change is closely followed by a change in duration.
Neural Evidence of Statistical Learning: Efficient Detection of Visual Regularities Without Awareness
Evidence of learning emerged early during familiarization, showing that statistical learning can operate very quickly and with little exposure, and the findings help elucidate the underlying nature of statistical learning.
Adaptation in the auditory system: an overview
The multiple types of adaptation that occur in the auditory system are reviewed, which are part of the pool of resources that the neurons employ to process the auditory scene, and are critical to a proper understanding of the neuronal mechanisms that govern auditory perception.
