[PDF][PDF] Slope of the power spectral density flattens at low frequencies (< 150 Hz) with healthy aging but also steepens at higher frequency (> 200 Hz) in human …
S Aggarwal, S Ray - Cerebral Cortex Communications, 2023 - academic.oup.com
The power spectral density (PSD) of the brain signals is characterized by two distinct
features: oscillations, which are represented as distinct “bumps,” and broadband aperiodic …

Healthy ageing and cognitive impairment alter EEG functional connectivity in distinct frequency bands
Functional connectivity (FC) indicates the interdependencies between brain signals
recorded from spatially distinct locations in different frequency bands, which is modulated by …

Auditory and visual gratings elicit distinct gamma responses
Sensory stimulation is often accompanied by fluctuations at high frequencies (> 30 Hz) in
brain signals. These could be “narrowband” oscillations in the gamma band (30–70 Hz) or …

Alpha and SSVEP power outperform gamma power in capturing attentional modulation in human EEG
Attention typically reduces power in the alpha (8–12 Hz) band and increases power in
gamma (> 30 Hz) band in brain signals, as reported in macaque local field potential (LFP) …

Enhanced stimulus-induced and stimulus-free gamma in open-eye meditators
Visual stimuli induce" narrowband" gamma oscillations (30-70 Hz) that are linked to
attention/binding and attenuate with aging and neurodegeneration. In contrast, meditation …

Stimulus-induced gamma sources weaken but not shrink with healthy aging in human EEG
Aging alters brain structure and function, and studying such changes may help understand
the neural basis underlying aging and devise interventions to detect deviations from healthy …
