Relative to our previous discussion regarding how music effects behavior,
consciousness being related to 40 hertz, and their effect on attention,
a recent communication from Wolfgang Skrandies adds new information
relevant to these topics.

Music is related to 8 hertz, 8 hertz is related to retrieval of long term
information,
8 hertz is a harmonic of 40 hertz.  40 hertz is related to consciousness.
40 hertz is the natural frequency that would occur from electrons in water
in a microtubule from quantum entanglement.

Wolfgang Skrandies's full paper is in press in "Neuroscience Letters"
entitled Electroencephalographic Cortical Oscillations and Saccadic Eye
Movements
in Humans by W.  Skrandies and E. Anagnostou, School of Medicine
Justus-Liebig University,  35392  Giessen,  Germany

Skrandies and Anagnostou have observed "cortical oscillations in humans
preceding eye movements. It turns out that oscillations in the alpha and beta
bands
PRECEDING a saccade by 256 ms determine whether a given subject will
make a regular or an express saccade."

Attention is related to expressed saccade.

ABSTRACT:

>A model predicting different types of saccades has suggested that the
>presence of rhythmic brain activity determines whether a subject will
>produce regular or express saccades. We studied cortical oscillations
>preceding saccadic eye movements.
>Brain electrical activity was recorded in 9 healthy adults continuously
>from 30 electrodes while subjects performed saccades. In a so-called gap
>
>condition multimodal latency distributions resulted. Express saccades
>were preceded by dif-ferent oscillatory activity than regular saccades.
>This was a highly significant finding restricted to the alpha and beta
>bands of the EEG. Step-wise discriminant analysis showed that cortical
>oscillations measured from only few electrode sites allowed to predict
>reliably which type of saccade a subject will make.
>These findings support the notion that stimulus-induced oscillations of
>the human EEG may modulate thresholds for triggering saccades.
