A Stimulus Plan?

New research looks at the growing interest in brain stimulation devices, and reports regulating them may prove to be tricky.

Deep Brain Stimulation to Treat Obesity?

Electrical brain stimulation targeting the “dysregulated reward circuitry” could make deep brain stimulation a new option for the difficult-to-treat problem of obesity.

Pupil Dilation Reveals Sexual Orientation

Researchers used a specialized infrared lens to measure pupillary changes to participants watching erotic videos. Pupils widened most to videos of people who participants found attractive, thereby revealing where they were on the sexual spectrum from heterosexual to homosexual.

Controlling Monkey Brains and Behavior With Light

Researchers can control the behavior of monkeys by using pulses of blue light to very specifically activate particular brain cells. The findings represent a key advance for optogenetics, a state-of-the-art method for making causal connections between brain activity and behavior. Researchers say that similar light-based mind control could likely also be made to work in humans for therapeutic ends.
