Pulsed Light Stimulation
Conversely, standard out phase occurs when the left eye is on and the right eye is off, continuing in an alternating fashion. Just as out phase is the opposite of in phase, alternating light stimulation tends to have an inhibiting effect on achieving the desired brainwave.
Independent light stimulation (ILS) is like a visual binaural beat. For example, your left eye is receiving 12 Hz stimulation and your right eye is receiving 18 Hz. What this light stimulation is actually creating is an offset frequency of 6 Hz, which is associated with the theta brainwave state.
The in phase and out phase of independent light stimulation means basically the same as the standard phases: being in synch or alternating. It is a little more complicated because different frequencies are being utilized. However, ILS phase techniques are very useful. For instance, by stimulating one eye with a high frequency and the other eye with a much lower frequency, you can actually activate or “excite” one hemisphere of your brain more so than the other. Or you may wish to activate both hemispheres simultaneously for accelerated whole brain learning.
What phase your light stimulation is set on greatly determines your session experience. Experiment with the different phases. Try short sessions combined with the various types of audio stimulation and make note of the mental, emotional and physical sensations you experience. Ask yourself which phase or combination of phases work best for you.
The duty cycle of light stimulation is for knowing how long the lights are on and off. So if the duty cycle is 60%, the lights will be on for 60% of the time and off 40%. Or if the duty cycle is 20%, that means the lights are on for 20% and off for 80% of the time. The higher the duty cycle, the brighter the lights appear. The lower the duty cycle, the sharper or more distinct the lights appear. Always vary the duty cycle when creating sessions as this will enhance the entrainment value and visual effects sensations of your session experience.
Intensity is how bright the light stimulation is. Light intensity is always user controlled. The beginning light and sound user should begin with the intensity at a very low level. As more sessions are experienced, tolerance to light stimulation will increase. Gradually increase the light intensity as your tolerance increases. Remember: brighter is not always better, comfort is more important.
