Auras
an article describing how auras are propagated in the human brain The Myth of the Mind's Aurora Auroras do not propagate in the human brain, as they are large-scale space weather events that occur exclusively in Earth's upper atmosphere. Because the human body is shielded by Earth’s magnetic field and atmosphere, the literal atmospheric phenomena cannot occur inside human tissue. However, the phrase "auroras in the brain" is frequently used as a metaphor in science journalism, art, and neuroscience to describe complex electrical patterns, optical illusions, or specific medical conditions. Why Auroras Only Happen in Space To understand why auroras cannot exist in the brain, it helps to look at what actually creates them: Solar Wind: The sun ejects a constant stream of charged particles (electrons and protons). Magnetic Shielding: Earth's magnetic field channels these particles toward the polar regions. Atmospheric Collision: The particles collide with gases li...
