More than two years after several dozen U.S. embassy workers in Cuba reported experiencing bizarre sensory symptoms, including loud noises and unusual vibrations, exactly what happened to them remains a mystery.
Now, a new study adds to the intrigue.
Study - Technologies - Differences - Brains - Workers
The study, which used advanced brain-imaging technologies, revealed distinct differences in the brains of embassy workers who were potentially exposed to the bizarre phenomena, compared with healthy people who were not exposed.
Run, Bear, Run!
Finding - Number - Workers - Abnormalities - Balance
This finding is notable given that a number of the embassy workers show abnormalities in balance and coordination of eye movements, said study co-author Dr. Randel Swanson, an assistant professor of physical medicine and rehabilitation at the University of Pennsylvania's Perelman School of Medicine. However, the researchers acknowledge that they can’t say exactly what their findings mean or what caused the brain differences. In other words, the study doesn't bring us any closer to understanding the cause of the alleged phenomena.
Still, it appears that "something happened to at least a subset of [these] patients," Swanson told Live Science.
Brain - Differences - Images - Symptoms - Workers
It's possible that the brain differences seen on the images may underlie some of the symptoms documented in the embassy workers, he said.
US - Workers - Havana - Noises - Vibrations
In late 2016, some U.S. embassy workers serving in Havana reported hearing sudden, loud noises or feeling vibrations or movement in the air around them, Live Science previously reported. These experiences were followed by a variety of neurological symptoms, including dizziness, balance problems...
