Electric field effects in tne brain

Click For Summary

Discussion Overview

The discussion revolves around the effects of electric fields in the brain, particularly focusing on the endogenous electric fields generated by cortical neurons and their potential global modulating effects. Participants share personal experiences related to these phenomena and explore implications for modeling and health.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant references a study suggesting that the electric fields from cortical neurons may have a feedback effect on brain activity.
  • Another participant indicates the need to incorporate a mutual inductance term into their model, implying a complexity in modeling brain activity.
  • A participant shares a personal experience of a frightening moment during sleep, describing sensations that could be interpreted as related to brain electric fields, though they express uncertainty about the terminology and implications.
  • In response to the personal experience, another participant suggests that the described sensations may be hypnopompic hallucinations, linking them to anxiety and stress responses.
  • One participant expresses concern for their health and mentions plans to see a doctor, indicating a personal stake in the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the interpretations of personal experiences or the implications of electric fields in the brain. Multiple competing views and interpretations remain present throughout the discussion.

Contextual Notes

Some participants express uncertainty regarding the terminology and definitions related to their experiences, and there is a lack of clarity on the physiological implications of the electric fields discussed.

Who May Find This Useful

Readers interested in neuroscience, personal health experiences related to brain activity, and the implications of electric fields in cognitive processes may find this discussion relevant.

This study presents evidence that the complex endogenous (internal) electric field generated by the activity of individual cortical neurons exerts a feedback which has a global modulating effect. The linked summary links to the full article (PDF). (The second link is a bit slow as this is a long article)

Great, thanks a lot. Now I have to add a mutual inductance term to my model.

Quite a few of them I would think.
 
Maybe i heard my brain's electric field switch off and on for a split second?

One night when i was sleeping and for the first time ever while in a deep sleep
(only way i can describe it but like a Physorg article said , it's really interesting
how deeply/closely the mind and body is connected) anyhow as i was saying:

That night while in deep sleep "something
warned me that something was not right" It was as if i knew that i might not wake up again, as if my brain prepared me for my final moment. before i continue...

I do not know what it is called, or what it is, and if there is a term to describe it.
It is as if when you are fast asleep, you become aware of your life support system. That night it was as if i heard inside my brain that something was switched off briefly, I can almost compare it to it sounding like a television set being switched off briefly, then it it came back on almost immediately. Never had such an experience.

But it was alarming and felt really frightening.

Suddenly i woke up. I took my pulse and found that after say every 18th beat
my heart skipped a beat, sometimes the skipping happenned more frequent.

Since that day, my heart rate was fine and it never re-occurred. I can tell you though,
i probably never was so frightened as i was that night.

I don't drink or moke and i was excersisng hard at that time, might've been
over excersising? But i do not really excersise a lot these days, only walking and hiking. I
have a history of strenious excersisng "if one could call it that" Maybe it had to do with over training and not enough rest.

i never had any heart trouble history.

Just wanted to share this, don't no why :) This is a great site, with many interesting people, and opinions.

What you've described does not sound like "your brain turned off", but rather something that is called a hypnopompic hallucination. The increase in heart rate was a result of surprise and fear, and the sensation of missing beats is called "palpitations" which is a response to anxiety and stress. You have no reason to be afraid for your life.
 
I am now going to see a doctor.
