Brain imaging studies investigate pain reduction by hypnosis
...c resonance imaging (fMRI) to find out if hypnosis alters brain activity in a way that might explain pain reduction. The results are reported in the November-December 2004 issue of Regional Anesthesia and Pain Medicine. The researchers found that volunteers under hypnosis experienced significant pain reduct...Brain-scanning technologies need standards, according to Stanford researcher
.... The question is whether this expensive screening alters the woman's care and is therefore something that should be covered by insurance. Radiologists say that in many cases the MRI screening adds valuable information and may alter a woman's medical care for the rest of her pregnancy.

Chicago have found that partial sleep deprivation alters the circulating levels of the hormones that regulate hunger, causing an increase in appetite and a preference for calorie-dense, high-carbohydrate foods.
