Lack of vision shifts occipital dynamics toward a frontal-like regime and enhances top-down connectivity

This study shows that blindness changes occipital cortex dynamics to resemble frontal cortex, enhancing top-down connectivity and linking faster dynamics to stronger frontal influence.

Temporal fingerprints of TMS-evoked potentials across thalamocortical circuits

The paper analyzes TMS-evoked potentials (TEPs) from different cortical regions to characterize their temporal features and relates them to network properties.

Critical dynamics in spontaneous EEG predict perturbational complexity in disorders of consciousness with measurable evoked responses

The paper shows that resting-state EEG criticality features predict perturbational complexity index (PCI) in disorders of consciousness, but only in specific patient subgroups.

Transcranial magnetic vs intracranial electric stimulation: a direct comparison of their effects via scalp EEG recordings

This paper compares the electrophysiological effects of transcranial magnetic stimulation (TMS) and intracranial electrical stimulation (IES) using scalp EEG recordings in different brain states.

The spatiotemporal evolution of TMS-evoked potentials reflects direct cortical activation

This study shows that TMS-evoked potentials (TEPs) can have distinct spatiotemporal patterns lasting up to 300 ms when targeting specific cortical areas, challenging the view that later components are due to sensory inputs.

Acute pain drives different effects on local and global cortical excitability in motor and prefrontal areas: Insights into interregional and interpersonal differences in pain processing

The paper examines how acute pain affects local and global cortical excitability in motor and prefrontal areas, revealing interindividual differences in pain processing.

TAAC - TMS Adaptable Auditory Control: a universal tool to mask TMS click

TAAC generates customized masking noises to reduce auditory confounds in TMS-EEG studies, achieving effective masking at lower sound pressure levels than standard methods.

The rt-TEP tool: real-time visualization of TMS-Evoked Potential to maximize cortical activation and minimize artifacts

The paper introduces rt-TEP, a real-time visualization tool for TMS-evoked potentials that improves signal quality and parameter optimization.

Local sleep-like cortical reactivity in the awake brain after focal injury

This study shows that focal brain injuries lead to local sleep-like dynamics in the surrounding cortex, disrupting signal complexity while coexisting with wakefulness patterns.

Assessing the Intra- and Inter-Subject Reliability of the Perturbational Complexity Index (PCI) of Consciousness for Three Brain Regions Using TMS-EEG

The paper assesses the reliability of the Perturbational Complexity Index (PCI) across three brain regions using TMS-EEG in healthy adults, finding high reliability for parietal and motor sites.

A fast and general method to empirically estimate the complexity of brain responses to transcranial and intracranial stimulations

The paper introduces PCIST, a fast method to estimate perturbational complexity of brain signals, validated on TMS/hd-EEG and SEEG data, showing comparable accuracy to the original PCI with improved speed and applicability.

Sleep-like bistability, loss of causality and complexity in the brain of Unresponsive Wakefulness Syndrome patients

This study links pathological bistability in UWS patients to reduced brain complexity using TMS/EEG and PCI measurements.

The Spectral Features Of EEG Responses To Transcranial Magnetic Stimulation Of The Primary Motor Cortex Depend On The Amplitude Of The Motor Evoked Potentials

This study investigates how the spectral features of TEPs from M1 TMS depend on MEP amplitude, finding a late ERD linked to MEP strength.
