MEG Noise reduction - Shielding

 

1. Passive 50-100 dB
A. Flux-entrapment shields (low frequency noise):
• Ferromagnetic, highly permeable m-metal (Nickel, Copper, Iron alloy).
• Ferrite materials.
B. Lossy magnetic shields based on induced eddy currents (high frequency):
• highly conductive materials (Copper, Aluminum, Iron, etc.).
• High Tc superconducting shields.
 
2. Active 10-20 dB
A. Zeroing coils: orthogonal Helmoltz coils around the room to eliminate
external fields.
B. Gradiometers: two or more coaxial pick-up coils connected in series.
 
3. Logic
A. Filters:
• band pass adequate to biomagnetic signals (1-100 Hz) to avoid
wideband thermal noise,
• rf filters on all cables.
B. Averaging repetitive signals.

Excerpt from the publication: "Science of the Heart" by The HeartMath Institute (p.20)

 

"The heart is the most powerful generator of electromagnetic energy in the human body, producing the largest rhytmic electromagnetic field of any of the body's organs. The heart's electrical field is about 60 times greater in amplitude that the electrical activity generated by the brain. This field, measured in the form of an electrocardiogram (ECG), can be detected a number of feet away from the body, in all directions, using SQUID-based magnetometers (Figure). Prompted by our finding that the cardiac field is modulated by different emotional states (described in the previous section), we performed several studies to investigate the possibility that the electromagnetic field generated by the heart may transmit information that can be received by others."

 

Thus, the last two studies summarized in this section explore interactions that take place between one person's heart and another's brain when two people touch or are in proximity. This research elucidates the intriguing finding that the electromagnetic signals generated by the heart have the capacity to affect others around us. Our data indicate that one person's heart signal can affect another's brainwaves, and that the heart-brain synchronization can occur between two people when they interact. Finally, it appears that as individuals increase psychophysiological coherence, they become more  sensitive to the subtle electromagnetic signals communicated by those around them. Taken together, these results suggest that cardioelectromagnetic communication may be a little-know source of information exchange between people, and that this exchange is influenced by our emotions.
