Alpha waves are electromagnetic oscillations in the frequency range of 8–12 Hz arising from synchronous and coherent ( in phase / constructive ) electrical activity of thalamic pacemaker cell...

Blind individuals have significantly lower alpha activity in the central derivation. In conclusion, the congenitally blind have visual content in their dreams and are able to draw it and, as expected, their VAI is negatively correlated with EEG alpha power...

In order to extract only the alpha activity related EEG signals of the brain, we have applied constrained Independent Component Analysis (cICA), a new extension of ICA in which some a priori knowledge of alpha activity ... The use of cICA might provide a more effective means of extracting EEG alpha activity of the brain.

Homepage of the Laboratory for Perceptual Dynamics ... We recorded scalp EEG activity preceded presentation of the dot lattices. We evaluated the power of EEG alpha activity in 1 s before dot lattice presentation. We found that vertical orientation bias was prominent in trials with low pre-stimulus alpha power.

We therefore measured subjective sleepiness and waking EEG power density in the range of 0.25-20 Hz after a single dose of melatonin (5 mg). During an 8 h mini-constant routine protocol, melatonin administered in a double blind cross-over design to healthy young men at 1300 h or 1800 h increased subjective sleepiness,

In addition to standard sleep staging of the records, alpha activity was scored using three methods: a) while the record was being scored, an assessment of alpha activity during the preceding stage was made at each stage change;
