Abstract

Rapid eye movement (REM) sleep and its main oscillatory feature, frontal theta, have been related to the processing ofrecent emotional memories. As memories constitute much of the source material for our dreams, we explored the linkbetween REM frontal theta and the memory sources of dreaming, so as...
