Stimulus predictability rather than inter-trial interval itself affects motor evoked potential amplitudes

This study shows that stimulus predictability, not just inter-trial interval duration, affects motor evoked potential amplitudes, with GABA-B-receptor mediated inhibition modulated by predictability.

Suppression of corticospinal excitability by sleep spindles without increase in GABAergic inhibition

The paper investigates how sleep spindles affect corticospinal excitability and GABAergic inhibition during NREM sleep using TMS and EEG, finding no significant phase-dependent modulation of SICI.

Sleep spindle state-dependent motor cortical plasticity induction by EEG-triggered ripple burst TMS

This study uses EEG-triggered rTMS during specific sleep spindle states to induce motor cortical plasticity, finding that spindle-trough stimulation consistently reduces corticospinal excitability.

Optimizing Network-Level TMS-fMRI: Benchmarking the TMS-Compatible Sushi MR Setup

The paper benchmarks a TMS-compatible Sushi MR setup for whole-brain fMRI, showing it matches a 64-channel reference in resting-state networks and improves task-fMRI with multi-echo combination.

Boredom and the representation of information content in the neocortex

This study investigates how the brain represents information content in sensory experience and links it to boredom-related behavior across humans and mice.

Modulating Brain Perfusion, Functional Connectivity, and Metabolite Patterns through Theta Burst Transcranial Focused Ultrasound Stimulation

This study examines the effects of theta-burst transcranial focused ultrasound on cerebral blood flow, functional connectivity, and metabolite levels in the primary motor cortex using multimodal neuroimaging.

Pulsed inhibition of corticospinal excitability by the thalamocortical sleep spindle

The paper uses real-time spindle detection to show that sleep spindles suppress corticospinal excitability during their falling flank, contributing to phase-dependent plasticity.

Spatiotemporal patterns of theta-band activity during rapid-eye movement sleep: a magnetoencephalography analysis

This study uses M/EEG to characterize theta-band activity during REM sleep, comparing it to working memory task-induced theta and identifying distinct spatial and frequency patterns.

Auditory confounds can drive online effects of transcranial ultrasonic stimulation in humans

This study shows that auditory confounds, not direct neuromodulation, drive motor inhibition from transcranial ultrasonic stimulation in humans.

Transcranial magnetic stimulation of primary motor cortex elicits a site-specific immediate transcranial evoked potential

The paper records immediate transcranial evoked potentials (i-TEPs) from TMS of the primary motor cortex and finds they are site-specific and modulated by stimulation parameters.

Ramped V1 transcranial ultrasonic stimulation modulates but does not evoke visual evoked potentials

This study uses ramped transcranial ultrasonic stimulation to investigate its effects on visual evoked potentials, finding no direct evoked potentials but modulation of VEPs when combined with a checkerboard stimulus.

Automated real-time EEG sleep spindle detection for brain state-dependent brain stimulation

This paper introduces a real-time EEG sleep spindle detection algorithm that enables automated stimulation during sleep spindles with high sensitivity and precision.

Transcranial Direct Current Stimulation Alters the Waveform Shape of Cortical Gamma Oscillations

This study shows that transcranial direct current stimulation (tDCS) changes the waveform shape of gamma oscillations in the visual cortex, specifically affecting the descending half-wave.

Specific changes in sleep oscillations after blocking human metabotropic glutamate receptor 5 in the absence of altered memory function

This study investigates the role of mGluR5 in memory processing during sleep and finds that blocking mGluR5 does not affect memory consolidation despite altering sleep oscillations.

Online Closed-Loop Real-Time tES-fMRI for Brain Modulation: Feasibility, Noise/Safety and Pilot Study

This paper describes a closed-loop tES-fMRI protocol for brain modulation, demonstrating feasibility, safety, and the ability to distinguish physiological changes from artifacts.

μ-rhythm extracted with personalized EEG filters correlates with corticospinal excitability in real-time phase-triggered EEG-TMS

The paper compares two EEG filtering methods for extracting the μ-rhythm and assesses their impact on corticospinal excitability measured via TMS.

The non-transcranial TMS-evoked potential is an inherent source of ambiguity in TMS-EEG studies

This study shows that TMS-evoked potentials (TEPs) include non-transcranial components from peripheral sensory and auditory processing, complicating interpretations of TMS-EEG studies.

Low-frequency alternating current stimulation rhythmically suppresses stimulus-induced gamma-band oscillations in visual cortex and impairs perceptual performance
