Neural prediction decorrelation reveals that adversarial robustness substantially improves DNN prediction accuracy across the entire human auditory cortex

Sounds synthesized to decorrelate model predictions across human auditory cortex show an adversarially robust CochResNet50 predicts fMRI responses far better than its standard counterpart, a gap hidden with natural sounds.

Music-selective cortex is sensitive to structure in both pitch and time

The paper shows that music-selective brain regions respond more strongly to music with intact pitch and temporal structure compared to scrambled versions, indicating their sensitivity to both note-level and pattern-level musical structure.

Convolutional neural network models describe the encoding subspace of local circuits in auditory cortex

The paper develops a linear-nonlinear subspace model that captures the encoding properties of convolutional neural networks in auditory cortex, showing they functionally match CNNs and reveal cell-type and layer-specific encoding differences.

Dynamic modeling of EEG responses to natural speech reveals earlier processing of predictable words

The paper models EEG responses to natural speech, showing predictable words are processed faster with earlier and smaller N400-like responses.

Neurons in auditory cortex integrate information within constrained temporal windows that are invariant to the stimulus context and information rate

Temporal integration in human auditory cortex is predominantly yoked to absolute time, not structure duration

The paper investigates how human auditory cortex integrates sound structures over time versus structure duration, finding that integration is primarily time-yoked.

The human language system, including its inferior frontal component in 'Broca's area', does not support music perception

This study investigates whether the language system, including Broca's area, supports music perception through fMRI and aphasia patient analyses, finding no engagement of language regions in music processing.

Preserved functional organization of human auditory cortex in individuals missing one temporal lobe from infancy

The paper shows that auditory cortex organization is preserved in individuals missing one temporal lobe, indicating hemispheric redundancy.

Distinct higher-order representations of natural sounds in human and ferret auditory cortex

This study compares neural representations of natural sounds in human and ferret auditory cortex, finding divergent processing at higher cortical stages for speech and music.

Music-selective neural populations arise without musical training

The paper shows that music-selective neural populations exist in individuals without musical training and respond to various music types and rhythms.

Intracranial recordings from human auditory cortex reveal a neural population selective for musical song

The paper uses intracranial recordings to show a neural population in human auditory cortex selectively responsive to musical song.

Multiscale integration organizes hierarchical computation in human auditory cortex

The paper develops a method to estimate neural integration periods in human auditory cortex and shows integration periods increase with cortical hierarchy, correlating with selectivity for acoustic features and sound categories.

Neural responses to natural and model-matched stimuli reveal distinct computations in primary and non-primary auditory cortex

The paper tests a sensory model of auditory cortex by comparing neural responses to natural and model-matched stimuli, finding divergent responses in non-primary regions that suggest higher-order computations.
