To test whether the exposure to a magnetic field simulating the one encountered by the International Space Station (ISS) orbiting around the earth may affect cognitive functions.
12 healthy men were exposed to the simulated magnetic field and another 12 were sham-exposed to the natural geomagnetic field. The simulation was simplified when compared with the real conditions to which astronauts are exposed; e.g. the duartion of exposure was shorter and only the head was exposed. Each participant underwent a 90-min session. In the first 30 minutes they solved a crossword, then they viewed a series of emotional pictures (15 minutes) and the last 45 minutes they performed attention tests.
|ばく露時間||continuous for 90 min|
|ばく露装置の詳細||pair of horizontal Helmholtz coils around the test person's head; coils with a diameter of 35 cm, consisting of 100 turns of 0.8 mm copper wire wound around an aluminum ring|
|Sham exposure||A sham exposure was conducted.|
There was no significant difference between the sham-exposed and the exposed group, except for a trend for the alertness test indicating faster reaction times under magnetic field exposure.
