The 'functional topography' approach has been applied to study alpha rhythms in infant twins during the second half-year of life. The experimental sample included 154 normal infants born at 32-41 weeks of gestational age. Their chronological age varied from 7.4 to 12.4 months.

Neurobiology of Aging, 2018
Alpha rhythm (AR) changes are the most pronounced electroencephalogram phenomenon in the aging brain. We analyzed them based on the inherent AR structure obtained by parallel factor analysis decomposition in the cortical source space. AR showed a stable multicomponent structure in 78% of sixty 20- to 81-year-old healthy adults.

Alpha rhythm and hypofrontality in schizophrenia
Acta Psychiatrica Scandinavica, 2008 Objective: To reveal the EEG correlates of resting hypofrontality in schizophrenia (SZ).Method: We analyzed the whole‐head EEG topography in 14 patients compared to 14 matched controls by applying a new parameterization of the multichannel EEG. We used a combination of power measures tuned for regional surface mapping with power measures that allow ...

Alpha Rhythm and the Pineal Gland
International Journal of Neuroscience, 1992Alpha rhythm is classically described as a bilateral posterior rhythm of substantially constant frequency in the range of 8-13 Hz which is enhanced by mental relaxation and blocked by attention. Since the full expression of alpha rhythm has been shown to occur coincident with puberty, it is possible that the establishment of alpha rhythm is subject to ...

Influence of ongoing alpha rhythm on the visual evoked potential
NeuroImage, 2008 The relationship between ongoing occipital alpha rhythm (8–12 Hz) and the generation of visual evoked potentials (VEPs) has been discussed controversially.

Dynamics of the human alpha rhythm: evidence for non-linearity?
Clinical Neurophysiology, 1999 OBJECT: For a better understanding of the physiological mechanisms responsible for alpha rhythms it is important to know whether non-linear processes play a role in their generation.

THE principal objection to the theory1,2 that extra-ocular tremor generates alpha rhythm has been the indisputable fact that it is possible to record it in some patients who have had both eyes removed3.

Personality and the Alpha Rhythm
British Journal of Psychiatry, 1967Since human electroencephalography was first introduced by Berger in 1929, there have been many attempts to correlate the alpha rhythm with various aspects of personality. Lemere (1936) first reported a relationship between “good” and “poor” alpha rhythms and cyclothymic and schizoid personalities respectively.

The 8–12 Hz rhythmical waveform that can be recorded from the scalp of most human subjects when their eyes are closed does not originate in brain tissue. It is generated by physiological tremor in the extra-ocular muscles modulating the field set up by the standing potential of the eye.
