A novel probe for fMRI traces connections between neurons, helping researchers map brain circuits that underlie behavior and perception.
Study provides insight into the behavioral function of dopamine signaling in the striatum.
Up to 12% of adult drinkers experience anxiety during a hangover. Researchers examine how some are prone to feeling more anxious when experiencing a hangover.
Study reveals the specific changes that occur in the brains of mice exposed to cocaine. The findings shed new light on the role of dopamine in addiction, and provide new insight into dopamine transmission in the brain.
New findings reveal exercise increases levels of endocannabinoids in the body. The findings may explain some of the beneficial effects of exercise on the brain and body.
Zebrafish whose brains lacked oxytocin during the first two weeks of life had impaired capacity for social interaction as they aged. Researchers also found oxytocin-producing neurons were critical for the development of dopaminergic neurons.
Diet influences dopamine and insulin signaling in the brain, which in turn directly affects the peripheral sensory response in fruit flies. This response influences what the fly decides to eat next.
The placebo effect combined with dopamine levels can determine whether symptoms of depression and social anxiety will improve in patients prescribed SSRI antidepressants. Researchers found the positive effect of the medications was four times higher in patients with high expectations the treatment would work compared to those with lower expectations.
