Surprise gates two distinct mechanisms to support memorability in music

The paper investigates how musical memorability relates to neural responses to surprise and expectation, finding a U-shaped relationship between surprise and memory performance.

Speech is defined by theta-gamma coupled acoustic rhythms, mapped onto segregated populations in human early auditory cortex

The paper shows that theta-gamma rhythms in human auditory cortex reflect speech acoustics, with distinct neural populations processing different speech timescales.

PolyRNN: A time-resolved model of polyphonic musical expectations aligned with human brain responses

The paper introduces PolyRNN, a model of musical expectations in polyphonic music, and shows it aligns with human brain responses recorded via MEG and intracranial EEG.

Adaptive oscillators provide a hard-coded Bayesian mechanism for rhythmic inference

The paper proposes that adaptive oscillators serve as Bayesian priors for rhythmic inference, demonstrating their ability to model human behavior better than existing models.

Dogs' sensory-motor tuning shapes dog-human vocal interactions

This study investigates how dogs' sensory-motor tuning influences their ability to comprehend human speech, finding that their comprehension relies on a slower speech rhythm than humans.

Scream's roughness confers a privileged access to the brain during sleep

This study shows that roughness in screams enhances neural processing during sleep and wakefulness, increasing sleep spindle activity and response reliability.

Salient 40 Hz sounds probe affective aversion and neural excitability

This study links interindividual differences in aversion to rough sounds with neural excitability at 40 Hz, showing correlations with anxiety levels and suggesting 40 Hz sounds as neuromarkers for conditions like autism and schizophrenia.

Imagined speech can be decoded from low- and cross-frequency features in perceptual space

The paper decodes imagined speech using low- and cross-frequency neural features from electrocorticography data, showing their effectiveness in perceptual speech spaces.

Selective enhancement of low-gamma activity by tACS improves phonemic processing and reading accuracy in dyslexia

This study shows that tACS at 30 Hz enhances low-gamma activity in dyslexia, improving phonemic processing and reading accuracy.

Premature commitment to uncertain beliefs during human NMDA receptor hypofunction

This study investigates how NMDA receptor hypofunction affects cognitive inference under uncertainty, finding impaired decision-making and altered brain activity patterns.
