Independent Basal Ganglia Neural Populations Encode Speech Production and Ambient-Noise Levels

The paper investigates how basal ganglia activity encodes speech production and ambient noise levels in humans, finding distinct neural populations for each.

Revisiting the auditory hemodynamic response function in the era of fast fMRI

This study uses fast fMRI to characterize voxelwise auditory hemodynamic response functions (HRFs) and finds diverse, reliable, and regionally specific HRFs not captured by standard models.

Statistical learning dynamically shapes auditory perception

The paper investigates how statistical learning of probability distributions affects auditory perception and decision-making, finding that it dynamically shapes sensitivity and introduces perceptual biases.

A hierarchy of processing complexity and timescales for natural sounds in human auditory cortex

The paper uses deep neural networks to model neural responses in human auditory cortex and finds gradients of processing complexity and integration timescales across brain regions.

Spike-phase coupling of subthalamic neurons to posterior opercular cortex predicts speech sound accuracy

The paper shows that spike-phase coupling between subthalamic nucleus neurons and posterior opercular cortex predicts speech sound accuracy during speech production.

Category learning drives cortical attentional gain to diagnostic dimensions

The paper shows that category learning enhances attentional gain to diagnostic perceptual dimensions in auditory cortex, as evidenced by neural prioritization of relevant frequency bands during task performance.

Functional Heterogeneity of Voice-Encoding Cortex Revealed by Clinical Language Mapping

The paper investigates functional heterogeneity in voice-encoding cortex using electrophysiological and clinical stimulation mapping in patients with sEEG, finding overlapping roles in voice encoding and language.

Intracranial Mapping of Response Latencies and Task Effects for Spoken Syllable Processing in the Human Brain

This study uses intracranial recordings to map speech processing latencies and task effects across the human forebrain, revealing hierarchical and parallel information flow and task-related neural responses.

Auditory cortical responses to speech are shaped by statistical learning of short-term speech input regularities

The paper investigates how auditory cortical responses to speech are influenced by short-term statistical learning of speech input regularities, showing that cortical responses adapt based on context and expectations.

Short-term perceptual re-weighting in suprasegmental categorization

The paper shows that listeners adjust the perceptual weight of acoustic speech dimensions during suprasegmental categorization, down-weighting less relevant dimensions in accented speech.

Robust and efficient online auditory psychophysics

This paper introduces procedures for conducting online auditory psychophysics with high auditory hygiene, demonstrating reliable threshold estimates and frequency-selective attention measurements in a short time.

Categorical encoding of voice in human superior temporal cortex

The paper uses human intracerebral recordings to show that voice is encoded categorically in STG and STS, not by acoustic features, and this selectivity increases along the auditory hierarchy.

Subthalamic nucleus and sensorimotor cortex activity during speech production

The paper examines high gamma activity in the subthalamic nucleus and sensorimotor cortex during speech production, finding articulator-specific signals in both regions with similar timing but different topographical organization.

Tailored perception: listeners’ strategies for perceiving speech fit their individual perceptual abilities

The paper shows that individuals with pitch perception deficits use different perceptual strategies to process speech, relying more on duration cues and compensating for their deficits in speech and music perception.

Subthalamic nucleus neurons differentially encode early and late aspects of speech production

The paper examines subthalamic nucleus neuron activity during speech production, finding distinct firing rate changes related to speech planning and execution.

Extensive Tonotopic Mapping Across Auditory Cortex Is Recapitulated By Spectrally-Directed Attention, And Systematically Related To Cortical Myeloarchitecture

This paper shows that spectrally-directed attention modulates auditory cortex activation in a way that mirrors tonotopic organization and correlates with myeloarchitecture.
