Fathers who use cocaine at the time of conceiving a child may be putting their sons at risk of learning disabilities and memory loss. The findings of the animal study were published online in Molecular Psychiatry by a team of researchers from the Perelman School of Medicine at the University of Pennsylvania. The researchers say the findings reveal that drug abuse by fathers -- separate from the well-established effects of cocaine use in mothers -- may negatively impact cognitive development in their male offspring.
This week in the JCI, a study led by Michael Scott at the University of Virginia explores how stimulation of a subset of neurons that produce glucagon-like peptides can control appetite and glucose levels in lean and obese mice.
A survey in the US notes a consistent increase in the occurrence of condomless anal sex among men, as well as a rise in how many sex partners they have. Although antiretroviral therapies (ART) have revolutionized the treatment and prevention of HIV infections, knowing that they have ART as a back-up makes people complacent. This can lead to increased risks, says study leader Seth Kalichman in an article in Springer's journal Archives of Sexual Behavior.
Scientists at The Scripps Research Institute (TSRI) have found that deep brain stimulation (DBS) can greatly reduce the compulsion to use heroin in standard rat models of addiction.
A new study led by scientists at The Scripps Research Institute (TSRI) is giving researchers a first look at the early stages of brain development in patients with Fragile X syndrome, a disorder that causes mild to severe intellectual disability and is the most common genetic cause of autism spectrum disorder.
The ancient impulse to procreate is necessary for survival and must be hardwired into our brains. Now scientists from the University of North Carolina School of Medicine have discovered an important clue about the neurons involved in that wiring.
While laws placing age limits on the purchasing of e-cigarettes are intended to reduce the use of tobacco products, a recent study shows an unintended consequence: a rise in traditional cigarette smoking among pregnant teens. But the uptick in cigarette smoking did not produce negative birth outcomes, according to research by Princeton University and Cornell University, who analyzed more than 500,000 births among teenagers in the United States.
Teenagers who play video games for more than four hours a day suffer from symptoms of depression, but frequent use of social media and instant messaging may mitigate symptoms of game addiction in these teens, new Johns Hopkins Bloomberg School of Public Health-led research suggests.
More than two in three adults in the United States are considered overweight or obese, with substantial biomedical and clinical evidence suggesting that chronic overconsumption of a 'western diet' -- foods consisting high levels of sugars and fats -- is a major cause of this epidemic. New research by scientists at the University of California, Riverside now shows that chronic consumption of a western diet leads to overeating and obesity due to elevations in 'peripheral endocannabinoid signaling.'
This study shows how high estrogen release during the estrus cycle increases the pleasure felt via the brain's reward pathway
