“…These changes support the notion of enhanced motor cortex GABAergic inhibitory activity in elderly subjects. There are reports indicating that beta power in occipital regions is related to attentional modulation in the visual system [52]. Based on this finding, a decrease in beta band cortical activation during attentional modulation of visual motion processing in elderly people likely reflects age-related alertness deficits [53].…”

Healthy aging is associated with impairment in cognitive information processing. Several neuroimaging methods such as functional magnetic resonance imaging, positron emission tomography and near-infrared spectroscopy have been used to explore healthy and pathological aging by relying on hemodynamic or metabolic changes that occur in response to brain activity. Since electroencephalography (EEG) and magnetoencephalography (MEG) are able to measure neural activity directly with a high temporal resolution of milliseconds, these neurophysiological techniques are particularly important to investigate the dynamics of brain activity underlying neurocognitive aging. It is well known that age is a major risk factor for Alzheimer’s disease (AD), and that synaptic dysfunction represents an early sign of this disease associated with hallmark neuropathological findings. However, the neurophysiological mechanisms underlying AD are not fully elucidated. This review addresses healthy and pathological brain aging from a neurophysiological perspective, focusing on oscillatory activity changes during the resting state, event-related potentials and stimulus-induced oscillatory responses during cognitive or motor tasks, functional connectivity between brain regions, and changes in signal complexity. We also highlight the accumulating evidence on age-related EEG/MEG changes and biological markers of brain neurodegeneration, including genetic factors, structural abnormalities on magnetic resonance images, and the biochemical changes associated with Aβ deposition and tau pathology.

“…The high-frequency network was characterized by a shift towards more random topology, especially in the beta frequency band during resting state (Gaál et al 2010). Attentional modulation with age, related to alertness deficits or vigilance deficits, was conducted with a beta-band EEG decreased activity during a simple visual attention task in elderly with low behavioral performance accuracy (Gola et al 2012(Gola et al , 2013. Auditory-evoked low gamma band responses (38-40 Hz) following 40 Hz stimulation were also diminished with age in a study implementing phase-locking measures, which might be mediated by the GABAergic system (Griskova-Bulanova et al 2013).…”

The brain as a system with gradually declining resources by age maximizes its performance by neural network reorganization for greater efficiency of neuronal processes which is reflected in changes of event-related band responses (ERBRs) for sensory stimuli. Whether changes of high-frequency components of event-related responses are related to plasticity in neural recruitment during stabilization of sensory/cognitive mechanisms accompanying aging or are underlying pathological changes remains unknown.The effect of aging on beta (β1: 12.5-20; β2: 20.5-30 Hz) and gamma (γ1: 30.5-49; γ2: 52-69 Hz) band components of ERP was studied in an auditory discrimination task (low-frequency and high-frequency tone) at frontal, central, parietal and occipital cortical locations at short latency (post-stimulus interval 0-250 ms; putative sensory processing) and long latency (250-600 ms; putative cognitive) periods.Beta1 component of the short latency period of ERBRs was less affected by age. The beta1 activity of the long latency period was reduced by age and more widespread than in the short latency period. The aged difference in beta1 component spread into fronto-parietal regions and was more expressed after high-frequency than after low tone stimulation. Beta2 and gamma amplitudes were higher with progressive age during sensory processing. Reducing regional-process specificity with progressing age characterized tone-dependent beta2 changes during short latency (sensory), but not during long latency (cognitive) processing. Late latency (cognitive) beta2 and gamma activity diminished with age, except for the frontal high tone responses. With increasing age, gamma2 activity was more expressed over the frontal brain areas in high tone discrimination.We concluded that age influenced more the long latency (cognitive) processes than the short latency (sensory) ones.

“…The gamma band, for example, has been associated with recalling information in learning tasks [2] and was also observed in response to auditory mismatch negativity stimuli [3] while participants counted the deviant tones. Alpha band power has been found to increase in response to flicker stimuli [4] and beta power has been related to visual attention [5].…”

The response of the brain to a sensory stimulus may present itself in the electroencephalogram (EEG) as evoked and/or induced activity. While the evoked response is given by peaks and troughs in the signal, time-locked and phase-locked to the stimuli, the induced response is time-but not phase-locked, and can be considered as an increase or a decrease in the power of EEG in a specific frequency band at a specific time range with regard to the stimulus onset. The induced response does not have the same phase following successive stimuli. It is believed that cognition and perception of a stimulus present themselves primarily as the induced response in the EEG. In this paper, the induced response of the brain to auditory speech stimuli is investigated and different approaches to detect induced activity are compared. It is shown that there is an increase in theta and delta power in response to words compared to the baseline, starting around 500 ms after their onset. During this time, there is also an increase in pairwise coherence between the posterior electrodes. In response to tone bursts, a change in pairwise coherence was observed in the beta band starting around 200 ms. To the best of our knowledge, this is the first time such responses have been described using simple protocols without complex stimulus manipulations being involved. Responses in the EEG to speech rather than the more conventional tone-bursts or clicks suggests that it may be feasible to use the EEG as an objective means to demonstrate brain activation to salient real world stimuli. This would be of particular benefit in investigating access to speech in patients who are unable or unwilling to reliably respond to conventional subjective experimental protocols, such as infants.
