The Sileye-3/Alteino Experiment for the Study of Light Flashes, Radiation Environment and Astronaut Brain Activity on Board the International Space Station

In this work we describe the instrument Sileye-3/Alteino, placed on board the International Space Stationin April 2002. The instrument is constituted by an Electroencephalograph and a cosmic raysilicon detector. The scientific aims include the investigation of the Light Flash phenomenon, the measurement of the radiation environment and the nuclear abundance insider the ISS and the study of astronautbrain activity in space when subject to cosmic rays.
