The first biomagnetic signal was demonstrated in 1863 by Gerhard Baule and Richard McFee in a magneto-cardiogram (MCG) that used magnetic induction coils to detect fields generated by the human heart.

The heart's electrical field is about 60 times greater in amplitude than the electrical activity generated in the brain.

The magnetic signals generated by the heart have the capacity to affect individuals around us.

Heart-focused attention is associated with increased heart-brain synchrony, providing further support for energetic heart-brain communications.

One of the primary ways that signals and messages are encoded and transmitted in physilogical systems is in the language of patterns.

In the nervous system it is well established that information is encoded in the time intervals between action potentials, or patters of electrical activity.

Information is encoded in the space between nerve impulses and in the intervals between hormonal pulses. It's likely that information also is encoded in the interbeat intervals of the pressure and electromagnetic waves produced by the heart.

A useful technique for detecting synchronized activity between systems in biological systems and investigating a number of bioelectromagnetic phenomena is signal averaging.

When signal averaging is used to detect activity in the EEG that is time-locked to the ECG, the resultant waveform is called the heartbeat-evoked potential.

Changes in these evoked potentials associated with the heart's afferent neurological input to the brain are detectable between 50 to 550 milliseconds after the heartbeat.

There is a direct relationship between the heart-rhythm patterns and the spectral information encoded in the frequency spectra of the magnetic field radiated by the heart.

Information about a person's emotional state is encoded in the heart's magnetic field and is communicated throughout the body and into the external evironment.

This energetic communication can be enhanced, resulting in a much deeper level of nonverbal communication, understanding and connection between people.

This type of energetic communication between people may play a role in therapeutic interactions between clinicians and patients that has the potential to promote the healing process.

Although transmission of a clear QRS-shaped signal is uncommon over 6 inches, physiologically relevant information is communicated between people at much further distances and is reflected in synchronized activity.

The existing alpha rhythm is able to synchronize to extremely weak external electromagnetic fields such as those produced by another person's heart

It is possible for the magnetic signals radiated by the heart of one individual to influence the brain rhythms of another.

The degree of coherence in the receiver's heart rhythms appears to determine whether his/her brain waves synchronize to the other person's heart.

When a person is in a physiologically coherent state, he/she exhibits greater sensitivity in registering the electromagnetic signals and information patterns encoded in the fields radiated by others' hearts.

When people are able to maintain the physiological coherence mode, they are more internally stable and thus less vulnerable to being negatively affected by the fields emanating from others.

Synchronization of heart-rhythm patterns between individuals is possible, but usually occurs only under specific conditions.

Individuals who have a close working or living relationship are the best candidates for exhibiting true heart-rhythm synchronization.

Unlike in most wakeful states, synchronization between the heart rhythms of individuals can and does occur during sleep.

Large mammals have magnetoreception capability.

A type of heart-rhythm synchronization can occur in interactions between people and their pets
