I recently read an interesting article writtenby Maggie Fox Health & Science Editor Washington - (Reuters) who was citingan original article from within Science. This article was witten by Björn Rasch, Christian Büchel, Steffen Gaisand Jan Born of Lubek University Germany.
This article involved German researcherswafting the odour of roses over volunteers who were trying to rememberthings. When these volunteers were thenasleep inside an MRI scanner more rose odours helped them to remember 6% better than the control volunteers who didnt receive the odour. This effect was only during periodsof slow wave sleep (as opposed to REM sleep - when people are thought to bedreaming) and apparently acted on the hippocampus region of the brain which isassociated with learning.
Yet another reason to buy beautiful flowers !.
