Cognitive load modulates cortical excitability in the human prefrontal cortex

This paper uses TMS-EEG to show that prefrontal cortex excitability changes with cognitive load during a multi-source interference task, linking it to theta power and showing region-specific effects.

Recognizing EEG responses to active TMS vs. sham stimulations in different TMS-EEG datasets: a machine learning approach

This study uses a BiLSTM machine learning model to distinguish TMS-evoked EEG responses from sham stimulations across multiple datasets, achieving high accuracy with few trials.

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.

Sensory Entrained TMS (seTMS) enhances motor cortex plasticity

This study shows that sensory entrained iTBS (se-iTBS) significantly enhances motor-evoked potentials compared to standard iTBS, with effects lasting at least 30 minutes.

Sensory Entrained TMS (seTMS) enhances motor cortex excitability

This study introduces seTMS, a method that enhances motor cortex excitability by synchronizing TMS pulses with sensorimotor alpha rhythms using musical rhythms, resulting in larger motor-evoked potentials.

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.

Scalp EEG predicts intracranial brain activity in humans

The paper shows scalp EEG can predict intracranial brain activity in humans, with accuracy varying by region, depth, and frequency.

This paper develops a real-time closed-loop optimization method to enhance TMS-EEG measurements of prefrontal cortex excitability by reducing artifacts and increasing signal magnitude.

Reliability of the TMS-evoked potential in dorsolateral prefrontal cortex

This study evaluates the reliability of TMS-evoked potentials in the dorsolateral prefrontal cortex across different anatomical targets and analytical parameters.

Stimulation mapping and whole-brain modeling reveal gradients of excitability and recurrence in cortical networks

The paper uses electrophysiology and modeling to show that high-order brain regions have higher excitability due to recurrent feedback, revealing a gradient linked to cortical hierarchy.

Mapping cortical excitability in the human dorsolateral prefrontal cortex

The paper investigates how TMS location and angle affect early TEPs in the dlPFC and identifies optimal targets for enhancing EL-TEP responses.

Connectivity by the Frontal Aslant Tract (FAT) explains local functional specialization of the superior and inferior frontal gyri in humans while choosing predictive over reactive strategies: a tractography-guided TMS study

This study uses TMS and tractography to show that the SFG and IFG have opposite roles in predictive/reactive strategies, mediated by the FAT.
