New technology may help to unravel the mechanisms involved. Positron emission tomography and functional magnetic resonance imaging, for example, each allow a view of what happens to the central nervous system when acupuncture needles are applied, and acupuncture points can now be linked with specific brain cortices.
Successful breast feeding often depends on how long it takes for proper lactation to get started. Working on the hypothesis that delayed lactation may be linked to stress, researchers measured cortisol levels in a group of pregnant Guatemalan women during the first stage of labour and again after delivery. Not surprisingly, primiparous women …
