Comparison of the effect of hard and easy mental arithmetic upon blocking of the occipital alpha rhythm
3 shows, the EEG alpha rhythm
responded selectively in different cortical areas and, more importantly, there was a significant interaction between imagery vividness, localization and task.
The noted functional properties of the above-mentioned rhythm, its frequency characteristics, which may not coincide with the frequency of occipital alpha rhythm
, and the localization of its equivalent dipole sources, using the Brainloc method, has allowed the identification of the revealed EEG pattern as a reflection of the activation reaction of the hippocampus, involved in the pathological process.
We found that the alpha rhythm
is not just a marker of the transition between sleep and wakefulness but carries rich information about sleep stability," says Scott McKinney.
and Patton would probably like it a bit quicker.
Ian Power produced Noel Meade's Alpha Rhythm
from off the pace to lead on the run to the last and win the three-mile novices' hurdle by three lengths.
Carberry was at his inspired best on Alpha Rhythm
in the maiden hurdle, saving the 5-1 chance for one late burst when the race was all but over.
The worst-looking fall came in the two-mile maiden hurdle, when Alpha Rhythm
suddenly decided to duck out at the fourth and crashed into the running rail, leaving Murphy in a spectacular heap of horse flesh and
His experience can give him an edge over Alpha Rhythm
The control of electroencephalographic alpha rhythms
through auditory feedback and the associated mental activity.
In a newly published neurophysiological review, the scientists have proposed that mindfulness practitioners gain enhanced control over sensory cortical alpha rhythms
that help regulate how the brain processes and filters sensations, including pain, and memories such as depressive cognitions.
MEG measurements recorded instantly the participants' ability to adjust the alpha rhythms
in brain cells associated with the hand, depending on where their attention was directed.
