Summary: Research has shown that cortical tracking of natural speech is mainly influenced by acoustic processing, but also reflects speech-specific processing. The tracking of the amplitude envelope is strongest for the ENV stimulus regardless of which speech stimulus is recognized, with a positive relationship between intelligibility and tracking of perceived speech.

Summary: Many sensations experienced by an organism are caused by its own actions. Accurately predicting the sensory features and timing of self-generated stimuli is crucial for various behaviors. Research has shown that neural responses to self-generated sounds in the auditory cortex exhibit frequency-specific suppression, suggesting that movement-based predictions may occur early in sensory processing.

Summary: This study investigated the impact of temporal degradation on the intelligibility of Mandarin Chinese and Japanese, both tonal and non-tonal languages respectively. The researchers found that temporal degradation significantly affected speech cues other than tonal cues in degraded speech. The intelligibility of both languages remained high up to a segment duration of about 40 ms, but gradually decreased with longer segment durations, reaching a floor at around 150 ms or longer. The study also discovered a common temporal processing mechanism related to the limitations of intelligibility.

Summary: Working memory load can modulate the neural activity of different linguistic units during speech processing. Verbal and visual working memory load have similar effects on speech processing, possibly influenced by the domain-general component of the working memory system. Furthermore, working memory load asymmetrically affects lower-level auditory encoding and higher-level linguistic processing, reflecting the reallocation of attention induced by mnemonic load.

Summary: This study discusses the dependence of Mandarin syllables and tones perception on the speech envelope and the temporal fine structure. The results show that syllable perception mainly depends on the speech envelope, while tone perception depends on the temporal fine structure. The study provides important insights for auditory brain-computer interface and coding strategies for new hearing aids.

Summary: Speech and music, two spectrotemporally complex acoustic signals, are crucial for humans. While both contain temporal fine structures encoded in neural responses, recent research suggests that the neural mechanism enabling selective attention to one of two competing voices in speech may differ from that in music. Study results show that neural responses to the temporal fine structure of melodic lines in music can be measured, but attentional modulation was not observed in the context of the experiment.

Summary: When we listen to someone speak, our brain activity aligns with the incoming acoustic input. This study used magnetoencephalographic recordings to investigate the acoustic events that drive this alignment. The results showed that sustained acoustic fluctuations in the speech envelope were associated with speech-brain coupling in the theta-frequency range, while tracking of speech onsets in the low-frequency delta range was strongest. These findings suggest a temporal dissociation of acoustically driven oscillatory activity in auditory areas during speech tracking.

Summary: Pairing sound contrasts with VNS can significantly influence neural activity in the auditory pathway, leading to increased response strength and discriminability. However, pairing VNS with only one sound does not have the same effect on neural responses. Understanding the impact of different sound contrasts and neural activity patterns on plasticity could have important clinical implications for treating auditory processing disorders.

Summary: The study found that the Mismatch Negativity (MMN) system is powerful in establishing deterministic regularities but fails with a simple stochastic regularity. When a sound deviates from the predicted ones by the model, MMN is elicited, reflecting a prediction error. The research highlights the difference in the brain's ability to encode deterministic and non-deterministic regularities through auditory processing.

Summary: Research has found that visual cues misleading auditory expectations can trigger incongruency response in auditory event-related brain potentials, possibly due to a mismatch between auditory sensory expectations activated by visual predictive information and actual sensory input. The incongruency effect is more likely to occur with asynchronous presentation of visual-auditory combinations, suggesting a potential bimodal feature mismatch when violation of the visual-auditory relationship occurs.

Summary: The study revealed that participants could use relative pitch to detect new melodic patterns even in the absence of absolute pitch sensitivity. Event-related potentials (ERPs) showed the importance of relative pitch in information extraction, with an increase in behavioral reaction time. The data indicated that ERP indicators MMN and P3a were elicited even with only relative pitch information available, suggesting an impact on higher-level processing.

Summary: The study using event-related potentials found that the auditory system can extract implicit regularities even in the presence of acoustic distortions, although distortions led to decreased amplitude of mismatch negativity and P3a. Wrong-pitch distortions had a larger impact on P3a amplitude compared to white-noise distortions, likely due to interference with relevant pattern information.

Summary: According to the ideomotor theory, action can produce desired sensory outcomes, with action intentions resulting in reliable top-down predictions that modulate auditory brain responses. The extended auditory event representation system explains the effects of action intention on auditory processing and allows for studying the differences and commonalities with regularity-based predictions, guiding future research on action and perception.

Summary: The study found functional specialization in different fields of the rat auditory cortex, with the posterior auditory field showing the largest prediction error effects and other fields dominantly affected by repetition suppression effects. Results suggest that different AC fields have varying roles in context-dependent processing and being sensitive to stimulus-dependent effects in deviance detection.

Summary: It is remarkable how human listeners can perceive periodicity in noise, which lacks obvious physical cues. Previous research suggested that listeners rely on short temporally local and idiosyncratic features to perceptually segment periodic noise sequences. The present study aimed to examine the consistency of perceptual segmentation within and between listeners. Results showed that the consistency was stronger for interleaved periodic sequences, likely due to reduced temporal jitter. Additionally, the finding that certain noise sequences were segmented consistently across listeners challenges the assumption that the features are necessarily idiosyncratic.

Summary: Perceptual learning is a powerful mechanism for enhancing perceptual abilities and forming memory representations of unfamiliar sounds. The current study examined how the learning of random acoustic patterns is influenced by pattern repetition regularity and listener attention. The findings demonstrate that memory-related effects are observed even during the first occurrence of patterns, especially when listeners pay attention to the sounds.

Summary: The study found that lexical meaning has a modulating effect on auditory deviance detection, providing processing advantages for denotationally meaningful items, while word frequency did not have an effect. This suggests that even apparently low-level functions like auditory deviance detection utilize information from the mental lexicon for task-irrelevant stimuli.

Summary: Cholinergic (Ach), Noradrenergic (NE), and Dopaminergic (DA) pathways are crucial in regulating spatial attention and determining inter-individual differences in temperamental traits. This study found that temperamental traits predict individual differences in the ability to orient spatial attention based on the probabilistic association between cues and targets. These findings highlight the importance of considering temperamental and personality traits in social and professional environments where attention control is essential.

Summary: The processing of numerals as visual objects is supported by an Inferior Temporal Numeral Area (ITNA) in the bilateral inferior temporal gyri (ITG). Extant findings suggest some degree of hemispheric asymmetry in how the bilateral ITNAs process numerals. The study found that digit sensitivity did not differ between ITNAs, and digit sensitivity in both left and right ITNAs was associated with calculation skills. The study also revealed a right lateralization in engagement in alphanumeric categorization, and that the right ITNA showed greater discriminability between digits and letters.
