On each side of the brain stem, a fluorescent green marker illuminates the two networks of 200 neurons that control the sighing reflex, in an image from researchers at UCLA and Stanford. Sighing maintains normal lung function by re-inflating collapsed alveoli. Identifying the neurons responsible not only provides useful information on the link between brain and behavior, but could be of therapeutic use to help people whose sighing reflex goes into overdrive due to anxiety or psychiatric disorders.
