Ray WJ, Cole HW EEG alpha activity
reflects attentional demands and beta activity reflects emotional and cognitive processes.
A high level of alpha activity
counts as a marker of the readiness of the brain to exploit new incoming information.
Crabbe and Dishman (2004) conducted a metaanalysis examining EEG responses during and after exercise and concluded that when compared to pre-exercise, alpha activity
(absolute power) was greater both during and following exercise, but there was no differences in relative alpha activity
Modulation of gamma and alpha activity
during a working memory task engaging the dorsal or ventral stream.
The revealed features of the alpha activity
topography in damage to limbic structures allow us to extend the customary concepts in clinical electroencephalography of the interpretation of EEG interhemispheric asymmetry in conditions of organic brain pathology.
One of the general findings from EEG research in this area has been that an increase in alpha activity
, commonly seen as skill level increases, is not simply indicative of cortical deactivation, but is indicative of neural reorganization concomitant with the acquisition of more efficient, task-specific cognitive and motor processes (Nunez, 1995; Smith, McEvoy, & Gevins, 1999).
1982) Bilateral hemispheric alpha activity
during visual imagery.
It was expected that, in comparison with the HC individuals, the AC ones would show lower alpha activity
while solving creative problems.
Gross alpha and beta activity in bone: For gross alpha activity
in bone, there was a significant difference (ANOVA, p < 0.

Measurements along the EEG alpha activity
scale show the degree of attentiveness in a person, he explained.
