The aim of this work was to study the changes on different parameters of brain electrical activity (EEG) produced by a 4 moth Autoallusive meditation training during two experimental conditions, rest and concentration in respiration, in nonexperienced subjects. EEG of 8 meditation trained (EG) and 8 control (CG) subjects was recorded during rest (BL) and during concentration on respiration before and after the training. In the EG vs CG: absolute power decreased, alpha2 relative power increased during concentration and alpha2 interhemispheric correlation increased during BL, from pre to post-training. In both groups: alpha1 relative power increased on Bt on the post-training; alpha2 interhemispheric correlation was higher during concentration. Changes in the experimental group could be interpreted as a higher alert and more relaxed state, with higher functional sinchronization between cerebral hemispheres, produced by meditation training.

Series of ideas are presented about a new psychophysiology of consciousness called "The syntergic theory." The theory postulates that the human brain is able to create a hypercomplex field of interactions that are the result of the activation of all its neuronal elements. This interaction matrix is called the "neuronal field." One of the effects of its activation is the unification of neuronal activity. It is postulated that the neuronal field produces a distortion in the basic space-time structure and the reality of our percepts is the perception of this distortion. For the neuronal field to be activated a structure as complex as the brain is needed. This field is responsible for the interactions between brains produced in emphatic non verbal communication. Consciousness is closely connected to the neuronal Field. The postulates discussed are supported by the evidence from psychophysiology and the new physics.

Thirty-nine experiments were conducted with 24 pairs of subjects. EEG activity was recorded under different stimulation conditions, varying from one set of experiments to another. Transferred potentials were observed in approximately 25-40% of the cases. The topographical distribution of the potentials was found to be clearer in central and occipital regions.

It has been previously described in the literature that it is possible to increase the interhemispheric correlation (IC) of the EEG of human subjects through feedback training. These variations are statistically significantin relation to the control situation. However, it is not known how the outcome of the training is affected by the time that has elapsed between sessions. An experiment was designed to answer this question. The sessions were held weekly instead of the twice a week paradigm utilized in the former experiment. The IC of eleven neurologically healthy subjects, ages ranging from 21 to 50, was measured during a first block of six sessions. Thereafter, the group was divided into two groups, one continued as a control group while the other was subjected to biofeedback training. This second block lasted 10 weeks. Once the training was over, it was observed that the control group had no statistically significant increases in its IC values (t = 0.179, p(t) = 0.8653), neither had the experimental group (t = -0.653, p(t) = 0.5493). This leads to the conclusion that the time elapsed between biofeedback training sessions does have a significant effect on the learning process in terms of increased IC values. It is worthwhile mentioning that the IC of both groups showed a similar cyclical pattern lasting 5 weeks, however this phenomenon was not significant.

Einstein-Podolsky-Rosen (EPR) correlations between human brains are studied to verify if the brain has a macroscopic quantum component. Pairs of subjects were allowed to interact and were then separated inside semisilent Faraday chambers 14.5 m apart when their EEG activity was registered. Only one subject of each pair was stimulated by 100 flashes. When the stimulated subject showed distinct evoked potentials, the nonstimulated subject showed ''transferred potentials'' similar to those evoked in the stimulated subject. Control subjects showed no such transferred potentials. The transferred potentials demonstrate brain-to-brain nonlocal EPR correlation between brains, supporting the brain's quantum nature at the macrolevel.

EEG activity in monopolar derivations 01 and 02 was recorded in pairs of subjects while they remained inside two semisilent Faraday chambers, separated by aproximately 14.5 meters. One of the subjects of each pair was stimulated by 100 flashes while the other subject received no stimulus. Averages of the electrophysiological activity, synchronized with the stimuli, were obtained in both subjects before and after they had interacted. When the stimulated subject showed distinct evoked potentials, the non-stimulated subject showed none before interaction, but did show potentials similar to those evoked in the stimulated subject after interacting. These potentials we call Transferred Potentials. When the stimulated subject showed no distinct evoked potentials, the transferred potentials were absent in the non stimulated subject both before and after they interacted. Various control situations were conducted without the subject's knowledge. In one of the control experiments, random samples of brain activity without stimulation were taken and averaged. In others, stimuli were applied to an empty chamber with a subject located in the other chamber. In both cases, transferred potentials were not found. This shows that these potentials depend upon previous interaction and upon the evoked potential's conspicuous appearance, and shows that the Transferred Potentials are the result of a specific brain-to-brain relationship.

Correlation patterns between the electroencephalographic activity of both hemispheres in adult subjects were obtained. The morphology of these patterns for one subject was compared with another subject's patterns during control situations without communication, and during sessions in which direct communication was stimulated. Neither verbalization nor visual or physical contact are necessary for direct communication to occur. The interhemispheric correlation patterns for each subject were observed to become similar during the communication sessions as compared to the control situations. These effects are not due to nonspecific factors such as habituation or fatigue. The results support the syntergic theory proposed by one of the authors (Grinberg-Zylberbaum).

Clear differences were found in average evoked potentials (AEPs) recorded from parietal and temporal but not occiptal regions of 8 subjects when a vertical line was interpreted in some presentations as the number ‘one’ and at other times as the letter ‘I.’When upper and lower case versions of the same letter of the alphabet were presented, significant AEP differences were only found in occipital derivations. When different upper case letters were presented, significant AEP differences were found in all regions. These results indicate that the necessary operations to ‘extract’ a meaning from a stimulus take place in the parieto-temporal lobes while the analysis of its physical characteristics is done in the occipital lobes.

'Reality' can be conceived of as an undifferentiated energetic matrix. By means of the brain, this matrix is converted into neuronal activity and experience. This paper explores the manner in which human experience occurs by analyzing the characteristics of information present in space, the events associated with brain activity, and the interaction between the two. Human experience is considered to constitute or 'exist in' a dimension different from that which is related to the localized physiological activity of the brain. Between cerebral electrochemical changes and the experiences themselves of light, sound, love, fear, etc., energetic transformations of a qualitative nature must take place. These postulated transformations are discussed and a new theory (the syntergic theory) concerning the creation of experience is presented.
