Researchers in Spain have found that many of the individuals claiming to see the aura of people –traditionally called “healers” or “quacks”– actually present the neuropsychological phenomenon known as “synesthesia” (specifically, “emotional synesthesia”).
This might be a scientific explanation of their alleged “virtue”. In synesthetes, the brain regions responsible for the processing of each type of sensory stimuli are intensely interconnected. This way, synesthetes can see or taste a sound, feel a taste, or associate people with a particular color.
This is the first time that a scientific explanation is provided on the esoteric phenomenon of the aura, a supposed energy field of luminous radiation surrounding a person as a halo, which is imperceptible to most human beings.
In neurological terms, synesthesia is due to cross-wiring in the brain of some people (synesthetes); in other words, synesthetes present more synaptic connections than “normal” people. “These extra connections cause them to automatically establish associations between brain areas that are not normally interconnected”, professor Gómez Milán explains. Many healers and artists claiming to see the aura of people might have this condition.
