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.

Distinct neural temporal architectures encode rapid social expressions and sustained internal mood states

The paper identifies distinct neural mechanisms for encoding rapid facial expressions and sustained mood states using multimodal data from epilepsy patients.

Noninvasive profiling of input-output excitability curves in human prefrontal cortex

This paper characterizes human prefrontal cortex excitability using noninvasive TMS and EEG, finding sigmoidal input-output curves in 57% of participants and strong correlations between TMS-evoked potentials and motor-evoked potentials.

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.

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.
