Study the causes of epilepsy triggered by decrypted images

for people with light-sensitive epilepsy, flashing light can make them sick. However, some still images may also induce seizures. On May 8, researchers report in
journal That they may have found the cause of image-induced epilepsy through bulk scientific literature analysis.
, the researchers say, the focus is on gamma oscillation, a special pattern of repetition of nerve activity that is produced in the brain when people see certain images, such as black-and-white striped images. Such images can also cause other problems, such as migraines, especially for light-sensitive people, they said.
"Our findings suggest that when designing buildings, these visual patterns that activate the relevant loops and cause discomfort should be avoided. Dora Hermes of the Faculty of Medicine at the University of Udler in the Netherlands said.
gamma oscillations in the brain can be measured using electro-encephalograms, which scientists have been studying since the 1980s, but have not been able to agree on what these models mean for thinking, perception or neural activity.
new study, Hermes and his colleagues concluded that these images, which trigger gamma oscillations, can also induce epilepsy. But they also say there are simple ways to adjust images to suppress such brain activity. These adjustments include reducing contrast, adjusting stripe width, or changing the stripe image to a grid-like image.
findings suggest that existing gamma oscillation studies may provide important clues to understanding photosensitive epilepsy. Hermes' team is currently designing experiments to explore brain responses to these graphics in light-sensitive epilepsy patients and healthy people. They also plan to build new models to predict which natural landscapes or scenes ( such as urban landscapes, railway stations or interior designs) are most likely to trigger gamma oscillations and epilepsy
