Brain Connected To Low Frequency Micro Electric Waves?

Did Princeton's neurosccientists find out that all human brains are connected through extremely low frequency electromagnetic waves?
No credible evidence supports the claim that “all human brains are connected through extremely low-frequency electromagnetic waves,” and there is no such discovery reported by neuroscientists at Princeton.
Here’s what we know:

Origins of the Claim

• The idea seems to have circulated widely on social media platforms like Facebook, Instagram, Threads, and LinkedIn, with posts stating something along the lines of:
  “Princeton researchers found human brains emit ultra-low-frequency electromagnetic waves that form a coherent global neural network.” FacebookInstagramThreads
• However, these posts lack any credible sourcing—no academic papers, institutional press releases, or mentions in credible scientific media support the claim. Instead, fact-checking has labeled it as a bogus or false claim. Facebook

The Actual Science: ELF-EMF & the Brain1. Laboratory Studies (Only in Controlled Settings)
There are legitimate studies examining the effects of extremely low-frequency electromagnetic fields (ELF-EMF), typically in the range of 0–300 Hz, on brain activity. For example:

• Animal studies have suggested that exposure to ELF-EMFs can enhance neural plasticity and neurogenesis (the growth of new neurons), potentially affecting learning and memory in rodents. PMC+1

Important Caveat: These findings involve direct exposure in controlled laboratory settings, and reflect localized effects—not global, spontaneous brain-to-brain connectivity.
2. Brain-to-Brain Communication Theories
Some speculative theories explore the notion of brain-to-brain communication via electromagnetic phenomena, including concepts like ephaptic coupling (local electrical field interactions between neurons) or cemi field theory (the idea that consciousness arises from the brain’s own electromagnetic field).

• Johnjoe McFadden’s CEMI field theory suggests that electromagnetic fields generated within the brain could play a role in consciousness—but this theory remains controversial and is not widely accepted. WIRED

Summary TableClaim
Reality
Princeton neuroscientists discovered global brain-to-brain ELF-EMF connectivity
False—no study or evidence exists

ELF-EMFs have measurable effects on the brain
True—but only in controlled, localized experiments (e.g., rodents in lab settings)

Electromagnetic fields enable cross-human brain communication
False—no scientific support exists

 
However, none of these theories provide any evidence of electromagnetic connectivity across separate human brains.
