The frontal cortex undergoes macrostructural and microstructural changes across the
lifespan. These changes can be entirely physiological, such as the ones occurring in elderly
individuals who are cognitively intact, or pathological, such as the ones occurring in patients
with Alzheimer's disease. Here, we use simultaneous electroencephalography (EEG) and
transcranial magnetic stimulation (TMS) to study how the excitability of the frontal cortex
changes during healthy and pathological aging. Hence, we compared the TMS-evoked EEG …
