1. Science and Technology of Consciousness
Transcendental Consciousness
More details on EEG, coherence, etc are in the TM and EEG power point. You don’t need to emphasize coherence, EEG etc here.
After the Maharishi picture, there are slides on how EEG is generated. It is fairly technical….

15 leads of EEG over 40 sec.
The high amplitude regular EEG is alpha activity. Notice you see alpha EEG in the back, center and front.
Notice the breath quiescent period between the two arrows. It begins with an exhale and ends with an exhale suggesting a slow continous inhale throughout.
EDA is skin conductance, and above EDA is heart rate. Below EDA is heart rate variability.
The EDA going down is increase in sympathetic activity—this underlies greater alertness during TC.
The slowing of heart rate is increase in parasympathetic activity—this underlies greater silence during TC.
The desynchronized EEG in the middle of the slide is a hallmark of orienting—becoming aware of a significant experience.

9. Main Point
EEG power and coherence patterns during TM practice are similar to those seen during the transitions between waking, sleeping, and dreaming, though they last longer during TM practice. The junction point model states: “The three relative states of consciousness, exist and run through their continuous, ever-changing alternation on the basis of the fourth state underlying them.” Maharishi

11. How is “EEG” generated?

Action potentials result in positive or negative ions moving into the cell body. This creates a difference in charge that results in a flow of ions to balance the charger.

The move in ions along the neurons sums to form the electrical signal measured as EEG>
Brain waves measured by EEG mostly reflect electrical activity in the cortex, but include contributions from the whole brain.
