Action potential waveforms are state-dependent

The paper shows that action potential waveforms are state-dependent and not random, challenging the binary spike assumption in neural coding.

ScaleSurfer: multi-scale anatomical segmentation and parcellation of the human brain

ScaleSurfer rapidly estimates whole-brain morphometric features using a multi-scale vision transformer, achieving speeds up to five orders of magnitude faster than traditional methods.

NeuroVLM: A generative vision-language framework for human neuroimaging

NeuroVLM generates and evaluates vision-language models for human neuroimaging using 30,826 neuroimage-text pairs to perform tasks like text-to-image generation and image-to-text interpretation.

Aperiodic neural timescales in prefrontal cortex dilate with increased task abstraction

The paper analyzes EEG data to show that aperiodic neural timescales in prefrontal cortex increase with higher task abstraction during a cognitive control task.

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.
