Lesion of the Lateral Habenula Reduces REM Sleep Length

Caption

These are bar graphs showing the percentage of REM sleep (left graph) and the length of single REM episode in the animals with sham- (control, blue) and lesion-operated rats (Habenula-lesion, red). After sham- and lesion-surgery, hippocampal activity and electromyogram were recorded to determine the sleep stage. Destruction of the lateral habenula significantly reduces these two value suggesting that the lateral habenula is essential for the maintenance of REM sleep).
