Erotic images elicit strong response from brain

Red zones in this brain map suggest frontal parts of the brain are particularly sensitive to erotic content.A new study suggests the brain is quickly turned on and “tuned in” when a person views erotic images. Researchers at the School of Medicine measured brainwave activity in women as they viewed a series of slides that contained various scenes from water skiers to snarling dogs to partially-clad couples in sensual poses. When study volunteers viewed erotic pictures, their brains produced electrical responses that were stronger than those elicited by other material, no matter how pleasant or disturbing the other material may have been.

Central nervous system beckons attack in MS-like disease

Eliminating a molecular signal can help protect a neuron (show here) from destructive immune system cells.It may sound like a case of blame the victim, but researchers at Washington University School of Medicine in St. Louis have shown that cells in the central nervous system can sometimes send out signals that invite hostile immune system attacks. In mice the researchers studied, this invitation resulted in damage to the protective covering of nerves, causing a disease resembling multiple sclerosis. The researchers found that they could prevent destructive immune cells from entering nervous system tissue by eliminating a molecular switch that sends “come here” messages to immune cells.
