Divine Visions Decoded: Neuroscience and Psychology Behind Spiritual Encounters
Scientists Explain Religious Visions as Migraine Auras
For centuries, saints, mystics, and believers have described divine visions—celestial armies, radiant lights, and heavenly cities—as encounters with the divine. Modern science, however, offers a different explanation: migraine auras.
The Link Between Visions and Migraines
Neurologists note striking similarities between religious visions and the sensory disturbances caused by migraine auras. Affecting roughly 10% of people globally, migraines often include an “aura” phase: a wave of electrical activity in the brain’s visual cortex that triggers hallucinations. These manifest as shimmering zigzags (called “fortification patterns”), flashes of light, or even temporary blindness. Some experience auditory hallucinations or out-of-body sensations.
Dr. Philip Holland, a neuroscientist at King’s College London, explains, “A migraine aura is a wave of excitation traveling across the brain’s cortex. When it hits the visual cortex, it creates symptoms like flashing lights.”
Hildegard von Bingen: A Case Study
The 12th-century mystic Hildegard von Bingen documented vivid visions of stars, falling sparks, and divine light, which she attributed to God. She also described debilitating pain, writing, “The light threatens to kill me.” Neurologist Professor Stephen Silberstein suggests her experiences align with migraine auras. “The brain generates these hallucinations, and the individual interprets them through their cultural lens,” he says.
Von Bingen’s detailed artworks, featuring tessellating patterns and radiant shapes, may depict her aura-induced visions. Migraines can also cause “Alice in Wonderland Syndrome,” where perception of size and space distorts—a possible explanation for her descriptions of shrinking and growing.
The Science Behind Auras
Auras begin as a surge of neural activity, followed by a “reset” period where brain cells temporarily shut down. This explains why sufferers often see bright lights followed by darkness. MRI scans show aura patterns mirroring brain activity waves. Recent studies link these waves to chemical changes that trigger migraines.
While auras don’t always cause headaches, they sensitize nerves in the brain’s outer layers, leading to pain. “Migraines and auras are separate but related,” says Dr. Holland.
Why Auras Feel Divine
For premodern societies, these sudden, intense experiences defied explanation, making divine intervention a logical conclusion. As Silberstein notes, “You’re not imagining them—the brain creates these signals, and culture shapes their meaning.”
While science demystifies these visions, it doesn’t diminish their profound impact. For Hildegard and others, auras were a bridge to the sacred—a testament to how the brain’s wiring can inspire both awe and revelation.
In unraveling the mystery of migraines, we gain insight into history’s most enigmatic spiritual experiences—proving that even the divine can have a neurological blueprint.
