Non-rapid eye movement sleep 3D maze. Participants were then trained in the maze for 4 hours and later, during the various sleep cycles of nonREM sleep, REM sleep and wakefulness, they were scanned twelve times using a PET scan during the night. The PET scan demonstrated a higher blood flow in the hippocampus during SWS/non-REM sleep due to the training from the previous day while the control group exhibited no increased blood flow and they had not received the training the prior day. The brain activity during sleep, according to this study, would show the events of the previous day do make a difference.
Rapid Eye Mount telescope 24°x32° through an objective of 120 mm diameter. The instrument was optimized for photometry of fast transients with a best time resolution of about 0.1 s. The observatory is operated for the Instituto Nazionale di Astrofisica by the REM Team. Since its installation and commissioning at ESO, REM rapid and multi-band observations allowed to contribute to several important discoveries in some cases widely reported by ESO press releases; for instance, the observations a few seconds after its discovery of GRB060418, GRB06067A and GRB080319B. In addition, a larger set of observations of targets different from GRBs has been performed, securing long
