The 40 Hz modulated signal
is based on the observation that a 40 Hz signal is evident
in EEG recordings taken both during normal, waking consciousness,
and during REM sleep. It doesn't appear in non-REM sleep.
It has been called the " binding factor " for human consciousness,
including the most common states of consciousness.
In a normal healthy brain, there's not much point in putting in a 40
Hz signal. That particular wavelength is already occupied with the
brain's own 40 Hz signal. Inputting such a signal will probably not
have much effect. The idea in using this signal to induce altered states
is to modulate that signal so as to alter the state of consciousness.
A few people have tried this signal, and the preliminary reports are
very encouraging. As a single signal or combined with others, it seems
to have a good potential for altering states of consciousness.
A lot depends on where you place the coils when you're using it. A
good starting point, and one that has been extensively used with other
signals in laboratory settings, is to put the coils about an inch above
each ear (a bilateral temporal lobe presentation). Such a presentation
would not be targeted at any specific experience, but would rather
elicit experiences that an individual is most prone to.
For those interested in out-of-body experiences, one coil placed over
the angular gyrus might be sufficient to induce effects that progress
toward an OBE. One such report has already been received. The person
reporting had experience with OBEs in the past. It may be that, for
some individuals, this presentation will not induce OBEs, but will
rather increase their responsiveness to the exercises (such as guided
visualization and imaginative practices) popularly taught as OBE techniques.

An alternative
presentation with a chance of inducing and out-of-body
experience using this signal might be one coil in front
of and below the right ear, and one coil over the angular
gyrus on the right side. Having the two coils located
there will include much of the parahippocampal region,
the right temporal lobe, and the region between the temporal,
parietal, and occipital lobes. All of these areas have
been implicated in OBEs, including observations (published
in the 1950s) by the great neurosurgeon Wilder Penfield,
recently by Dr. Olaf Blanke, and by Dr. M.A. Persinger.
This signal has been used by very few people, and you
should consider it as an untested signal, because reports
from those using a are not yet numerous enough to justify
generalizations from them. The few reports from sessions
using it tend to validate the hypothesis on which it's
based. |
This signal has a constant tone. It's a MONO signal. The correct calibration
will be 10mG for either channel, when measured from one coil.
This signal can be used over both hemispheres, or either one by itself.
If you are going to try one hemisphere, you might like to begin with
the right.
The signal was developed to facilitate out-of-body experiences, and
out-of-body meditation and/or visualization techniques may meet with
more success if done while falling to sleep, about 90 minutes after
the session.As with all new signals, begin with short sessions. If
you choose to apply this to only one side of your head, it's best to
start with short sessions over each side.
If you experience any negative effects during or after a session using
this signal over one side only, you can apply it to the other side.
Please report your experiences.
If you aren't comfortable
using less well-tested signals, do not use this one.

signal is based on a pattern developed in the Laurentian University
Behavioral Neurosciences program under the direction of Dr.
M.A. Persinger, and is based on empirical laboratory results
obtained there. |
