The human brain consists of approximately 100 billion electrically active neurones that generate an endogenous electromagnetic (em) field, whose role in neuronal computing has not been fully examined. The source, magnitude and likely influence of the brain's endogenous em field are here considered. An estimate of the strength and magnitude of the brain's em field is gained from theo- retical considerations, brain scanning and microelectrode data. An estimate of the likely influence of the brain…

TLDR
A physically plausible EM field decomposition is posited and can be seen to operate as the collective action of virtual EM-boson composites visible only by "being" the fields, yet objectively appear as the familiar EM field activity.
The CEMI Field Theory: Closing the loop
Several theories of consciousness first described about a decade ago, including the conscious electromagnetic information (CEMI) field theory, claimed that the substrate of consciousness is the
The Electromagnetic Will
TLDR
It is argued that though this EM field-driven will is not free, in the sense of being acausal, it nevertheless corresponds to the very real experience of the authors' conscious mind being in control of their voluntary actions.

Several theories of consciousness first described about a decade ago, including the conscious electromagnetic information (CEMI) field theory, claimed that the substrate of consciousness is the
Initiation of Intentional Actions and the Electromagnetic Field Theory of Consciousness
TLDR
It is shown here that the sorts of EM fields proposed by the theory as being conscious can act only on neurons that are either identical with, or spatially close to, the neurons that generated those fields in the first place, which makes it difficult to see how putatively conscious EM fields could initiate bodily movements.
Brain: An Electromagnetic System Beyin: Elektromanyetik Sistem
TLDR
Locating consciousness in the brain's EM field, rather than the neurons, has the advantage of neatly accounting for how information located in millions of neurons scattered throughout the brain can be unified into a single conscious experience.
Difficulties with the Electromagnetic Field Theory of Consciousness: An Update
Two previously identified difficulties with the electromagnetic field theory of consciousness are discussed. The first difficulty is that, although spatiotemporal electromagnetic patterns covarying
Neural Circuits, Microtubule Processing, Brain’s Electromagnetic Field—Components of Self-Awareness
TLDR
The authors maintain that an effective comprehension of consciousness is important for health care professionals because its disorders are frequent medical symptoms in emergencies, during general anesthesia and in the course of cognitive disorders in elderly people.

Detection of magnetic evoked fields associated with synchronous population activities in the transverse CA1 slice of the guinea pig.
TLDR
It may be possible to refine the technique to study the genesis of MEG signals--i.e., the relationship between evoked fields and the underlying neuronal currents--in a mammalian CNS structure, since the electrophysiology of the hippocampus is well understood.
On the relation between somatic evoked potentials and fields.
TLDR
A more detailed account of the SEF as well as an analysis of its relation to the SEP and to the somatic pial response (SPR) are described, finding that theSEF recorded normal to the head provides essentially the same information as that provided by reported potential recordings from the exposed surface of the brain (the SPR).

Nonsynaptic modulation of neuronal activity in the brain: electric currents and extracellular ions.
TLDR
Field effects and ion fluctuations probably have modest effects during physiological activity but have a significant impact on epileptic seizures, and can sustain them in the absence of synaptic transmission.
Weak ELF Magnetic Field Effects on Hippocampal Rhythmic Slow Activity
TLDR
Results are consistent with the hypothesis that endogenous CNS oscillators are uniquely susceptible to field-mediated perturbation and suggest that the sensitivity of these networks to such fields may be far greater than had previously been assumed.

TLDR
A theory is presented which generalizes the activating function concept known from peripheral nerve stimulation and predicts the influence of electrical and geometrical parameters on the excitation threshold.
Perception's shadow: long-distance synchronization of human brain activity
TLDR
It is shown for the first time, to the knowledge, that only face perception induces a long-distance pattern of synchronization, corresponding to the moment of perception itself and to the ensuing motor response.

TLDR
An examination of the physical interaction of extremely-low-frequency electromagnetic fields with the body shows that such interactions are too weak to have a significant effect on human biology at the cell level.
Modulation by applied electric fields of Purkinje and stellate cell activity in the isolated turtle cerebellum.
TLDR
All groups of spiking elements showed a correlation between patterns of modulation by applied fields and dendritic orientation, which suggests the degree of differential polarization of the extended cable elements of the neurone by the applied field as the basic mechanism for field‐induced excitation or inhibition.
