Description
Mind entrainment is essentially the ability to control areas of the brain directly by listening or watching a recurrent stimuli. It was discovered that when exposing oneself to a repeating stimuli, such as a sound pulsing at 14 hz, or 14 times per second, then certain parts of the brain would replicate this pulse into actual brainwaves[1]. This ability allows for the generation of brainwaves that would not normally be present, allowing the user to experience states of consciousness that would normally be either accessible only to deep meditators or not at all. Since these are brainwaves normally inaccessible to the individual, one is capable of reducing symptoms resulting from the lack of the brainwave. This technique has been around since the ancient shamans who would have drums to allow for the easy entering of a meditative state. Now with computers, however, it is possible to produce a replicable experience with a consistent stimuli.
Products
Various companies use this technique in their products, for instance:
Methods
Binaural - This method consists of two seperate frequencies, one given to the left ear the other to the right. In the brain the brain wave produced equals the difference of the two, such that if one ear is given 220 hz and the other 238, the resulting brainwave produced is 18 hz. This method is used in the Centerpointe holosync program.
Isochronic - this method "pulses" noise on and off at a given frequency. Such that if a sound is bursted on off at a rate of 14 bursts per second, then the resulting brainwave is 14 hz.
Proven Protocols
Coming soon.
This section will contain the proven protocols (such as the result of a 10 hz entrainment being a state of relaxation) in the form of a table.
Research
"Results. Overall inattention, impulsivity and variability as rated by the TOVA improved significantly. The eight students from the SPALD-ING reading program who received [Audio-Visual Entrainment] improved their reading scores more than their classmates who served as controls. The results included normalization as recorded on the TOVA, substantial improvements in reading as recorded on the STAR, and improvements in general behavior as noted by teachers and parents."[3]
"An analysis of variance test of significance was used for all measures (Bruning & Kintz, 1987). Table I summarizes the results of cognitive changes for the first group of students (N-14). Significant differences were found on four of six variables. The Peabody Picture Vocabulary Test (PPVT), did not show a significant change in IQ, whereas the Raven Coloured Progressive Matrices did show a significant increase in IQ (p <05). Memory, reading, and spelling showed significant improvement (p <. 0 1 ). Although the change in arithmetic score showed improvement, the results were not significant."[1]
"This preliminary data suggests that use of AVS entrainment to challenge and stimulate the brain appears to result in improved functioning on intelligence tests, achievement tests, and behavior as rated by parents and teachers. The simplicity of use and the low cost of the equipment may make effective treatment for learning disabilities and attention deficit disorders available to many of the children who need it but who would otherwise never receive it.[1]"
