Scientists Develop Nasal Spray That Improves Memory
Date: 9.10.2009
New research in the **FASEB Journal** demonstrates role of **IL-6** on sleep-related consolidation of specific types of memories, particularly during late night REM sleep cycles.
To make this discovery, Marshall and colleagues had 17 healthy young men spend two nights in the laboratory. On each night after reading either an emotional or neutral short story, they sprayed a fluid into their nostrils which contained either interleukin-6 or a placebo fluid. The subsequent sleep and **brain electric activity** was monitored throughout the night. The next morning subjects wrote down as many words as they could remember from each of the two stories. Those who received the dose of IL-6 could remember more words.
