This is the first time that specific patterns indicating the state of consciousness were identified. Currently the monitoring [...]

fMRI and EEG Dream Catchers


1 May, 2013 | EEG, MRI

In a recent research conducted at the ATR Computational Neuroscience Laboratories in Kyoto, Japan, functional magnetic resonance imaging (fMRI) and Electroencephalography (EEG) systems were used to decipher dream images during the hypnagogic sleep stage; the stage experienced during the transition to and from sleep. The experiment focused on three subjects who were asked to fall asleep [...]
