This study shows reward reduces motor slowing during repetitive wrist tapping by increasing movement vigor, as indicated by higher muscle activity and sustained pupil dilation.

This study shows that pupil-based biofeedback modulates cortical excitability, EEG spectral slope, and P300 response, suggesting a link to phasic LC activity and central arousal.

This paper uses dynamic causal modelling to show that reduced self-inhibition in the sensorimotor cortex contributes to motor fatigability.

This study shows that human participants can voluntarily control their arousal state using pupil-based biofeedback, which modulates brainstem activity and physiological responses.

This study shows that non-stochastic, high-frequency transcranial alternating current stimulation (hf-tACS) with triangle and sine waveforms reduces visual contrast detection thresholds, similar to stochastic tRNS.

This study tests if transcranial random noise stimulation (tRNS) applied to the primary visual cortex or retina improves visual contrast detection, finding that V1 stimulation enhances performance while retinal stimulation does not.

This study shows that TMS-based neurofeedback training enables participants to selectively modulate corticomotor excitability of individual fingers during mental imagery without physical movement.

This study shows that transcranial random noise stimulation (tRNS) acutely lowers the resting motor threshold in human primary motor cortex, indicating increased neural responsiveness.

This study investigates whether rhythmic visual alpha/gamma stimulation affects perceptual switches in a bistable motion illusion and finds no modulatory effect.

The paper investigates motor fatigability in healthy adults through repetitive movements, finding that performance decline is linked to reduced surround inhibition in the primary motor cortex.

This study investigates whether rhythmic vibrotactile stimulation modulates tactile detection thresholds by entraining brain oscillations, finding both predictive effects and masking effects.

The paper investigates how neural responses to rhythmic vibrotactile stimulation depend on ongoing brain oscillations, finding that stimulation intensity and frequency alignment with endogenous beta activity affect phase synchronization.

This study uses tACS-fMRI to show that power-synchronized neural activity increases resting state fMRI connectivity, providing causal evidence for the role of power fluctuations in forming RSNs.
