Single-pulse transcranial magnetic stimulation (spTMS) applied to the primary motor cortex (M1) is widely used to assess corticospinal excitability through motor evoked potentials (MEPs). While trial-by-trial variability in MEP amplitude is thought to reflect dynamic shifts in cortical excitability, implications and neural underpinnings of gradual changes in MEP amplitude over the course of a spTMS session remain unexplored. We addressed this gap by investigating the relationship between slow MEP amplitude fluctuations and shifts in electroencephalography (EEG)-derived excitation/inhibition (E

EEG power measurements have shown correlations with human language abilities, though the results have varied. Alpha power, believed to be modulated by thalamo-cortical networks, reflects sensory information processing. Additionally, alpha power has been more distinctly associated with language abilities compared to other EEG frequencies. This could be due to different degrees of reliability across frequency bands. The aim of this study was to identify the most reliable power measures and investigate their relation to language abilities. A group of children (N = 37) and adults (N = 90) particip
