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 motivation to invest in social interactions is closely linked to the reward system via the activation of dopaminergic neurons.
Researchers explore the psychological and neurobiological basis of why listening to sad music often makes us feel good and lifts our spirits.
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.
A new study aims to shed light on the roles sub-regions of the nucleus accumbens play in addiction.
Study reveals dopamine neurons that play a role in learning and memory also drive motivation.
Increased levels of dopamine release in the basolateral amygdala as a result of stressful situations during infancy could lead to lasting behavioral issues and social difficulties, a new study reports.
Bach1, a protein that blocks the expression of genes associated with neuroprotection, has been implicated in Parkison's disease. Researchers say blocking Bach1 slows the deterioration of brain cells in preclinical models of Parkinson's disease.
A new rodent study uncovers a neural circuit in the brain that appears to govern pain-induced anhedonia. Altering the activity of this circuit restored motivation in pre-clinical models of pain.
