TLDR
In this article, the authors employed stimulus durations both beyond and within this temporal window in order to examine the genuine duration representation in the brain and found separate memory representations for sound duration and frequency in the human brain.Abstract:
Studies using a brain index for pre-attentive change detection, the mismatch negativity (MMN), suggested distinct neuronal populations for signaling changes in sound duration and frequency. However, these studies used only durations within the temporal window of loudness summation (ca. 200 ms) in which any duration change is accompanied by a loudness change. Hence, the present study employed stimulus durations both beyond and within this temporal window in order to examine the genuine duration representation in the brain. Magnetic mismatch responses (MMNm) for duration and frequency changes were compared with each other. The equivalent current dipole (ECD) of the duration MMNm was located in the auditory cortex slightly posterior to that for the frequency MMNm irrespective of stimulus duration. The results suggested separate memory representations for sound duration and frequency in the human brain.read more

Auditory processing that leads to conscious perception: A unique window to central auditory processing opened by the mismatch negativity and related responses
TL;DR: This revised model is mainly based on the mismatch negativity (MMN) and N1 indices of automatic processing, the processing negativity (PN) index of selective attention, and their magnetoencephalographic and functional magnetic resonance imaging (fMRI) equivalents.

Reduced mismatch negativity in posttraumatic stress disorder: A compensatory mechanism for chronic hyperarousal?
TL;DR: The data suggest a reduction in pre-attentive auditory sensory memory in PTSD due to specific symptom variables such as hyperarousal, sleeplessness, impaired concentration and a general enhanced excitation of the nervous system.

Left hemisphere specialization for duration discrimination of musical and speech sounds
TL;DR: This study provides behavioural evidence of a left hemisphere specialization for duration perception of both musical and speech sounds in line with the current view based on a parameter--rather than domain-specific structuring of hemispheric perceptual asymmetries.

Changes in the representation of space and time while listening to music.
TL;DR: It is concluded that research on the influence of music on the representation of space and time is still quite inconclusive but that integrating the different approaches could lead to a better understanding of the observed effects.

Early selective-attention effect on evoked potential reinterpreted ☆
TL;DR: The ‘Hillyard effect’ was explained as being caused by a superimposition of a CNV kind of negative shift on the evoked potential to the attended stimuli rather than by a growth of the ‘real’ N 1 component of theevoked potential.

TL;DR: In this article, the sequence of neurophysiological processes elicited in the auditory system by a sound is analyzed in search of the stage at which the processes carrying sensory information cross the borderline beyond which they directly underlie sound perception.

Right hemisphere dominance of different mismatch negativities
TL;DR: The results provide further evidence for the view that the MMN reflects a neural mismatch process with a memory trace which automatically codes the physical features of the repetitive stimuli.

The Neural Circuitry of Pre-attentive Auditory Change-detection: An fMRI Study of Pitch and Duration Mismatch Negativity generators
TL;DR: 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.

TL;DR: If the MMN generator process occurs where the stimulus information is stored, these findings strongly suggest that the frequency, intensity, and duration of acoustic stimuli have a separate neural representation in sensory memory.
