Single-neuron spiking variability in hippocampus dynamically tracks sensory content during memory formation in humans

This study shows that hippocampal spiking variability tracks sensory content during memory formation and correlates with memory retention in humans.

Evaluating and Comparing Measures of Aperiodic Neural Activity

This study evaluates and compares different measures of aperiodic neural activity, showing shared variance across methods and differences in their sensitivity to oscillatory activity.

A spatiotemporal complexity architecture of human brain activity

This study identifies complexity drops in functional MRI signals as a mechanism linking neural regularity to functional network architecture in the human brain.

Dynamic regulation of neural variability during working memory reflects dopamine, functional integration, and decision-making

This study examines how neural variability during working memory is regulated by dopamine, functional integration, and decision-making using PET and fMRI data.

Modality-specific tracking of attention and sensory statistics in the human electrophysiological spectral exponent

The paper shows that EEG spectral exponents reflect changes in E:I balance and selective attention, and track stimulus spectral exponents in sensory cortices, predicting behavioral performance.

Local cortical desynchronization and pupil-linked arousal differentially shape brain states for optimal sensory performance

The paper shows that local cortical desynchronization and pupil-linked arousal differentially affect perceptual processing in humans during an auditory task.

Prestimulus neural alpha power predicts confidence in discriminating identical auditory stimuli

The paper shows that lower prestimulus alpha power predicts higher confidence in auditory discrimination tasks, independent of stimulus evidence or task performance.

States and traits of neural irregularity in the age-varying human brain

This study uses weighted permutation entropy to quantify neural irregularity in EEG data, showing it correlates with age-related changes and influences perceptual decisions.
