April Flowers for redOrbit.com - Your Universe Online A research team from Inserm has published a new study in the journal Biological Psychology detailing the key role played by a protein, the CB1 cannabinoid receptor, during physical exercise. The team demonstrated, in studies conducted on mice, the location of this receptor - in a part of the brain associated with motivation and reward systems - controls the amount of time for which an individual will carry out voluntary physical...

Jackson Laboratory researchers led by Associate Professor Zhong-wei Zhang, Ph.D., have provided direct evidence that a specific neurotransmitter receptor is vital to the process of pruning synapses in the brains of newborn mammals. Faulty pruning at this early developmental stage is implicated in autism-spectrum disorders and schizophrenia. The definitive evidence for N-methyl-D-aspartate receptor (NMDAR) in pruning has eluded researchers until now, but in research published in the...

Scientists at Karolinska Institutet in Sweden have identified two molecules that play an important role in the survival and production of nerve cells in the brain, including nerve cells that produce dopamine. The discovery, which is published in the journal Nature Chemical Biology, may be significant in the long term for the treatment of several diseases, such as Parkinson's disease. The same scientists have previously shown that receptors known as "liver X receptors" or LXR, are necessary...

Works in brain like ketamine, with fewer side effects -- NIH trial A drug that works through the same brain mechanism as the fast-acting antidepressant ketamine briefly improved treatment-resistant patients' depression symptoms in minutes, with minimal untoward side effects, in a clinical trial conducted by the National Institutes of Health. The experimental agent, called AZD6765, acts through the brain's glutamate chemical messenger system. Existing antidepressants available through...

Light instantly triggers or reverses depression-like states in rodents -- NIH-funded studies A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced...

Following the birth of a child, new mothers may have an altered perception of stresses around them, showing less interest in threats unrelated to the baby. This change to the neuroendocrine circuitry could help the mothers adapt to the additional stress often accompanying newborns, say researchers from Indiana University's Kinsey Institute and the University of Zurich. When viewing disturbing images during the study, postpartum women reported less distress and demonstrated less activity in...

Fathers Are More Engaged Parents With Oxytocin
2012-12-11 10:50:19

April Flowers for redOrbit.com - Your Universe Online Oxytocin is a powerful hormone that plays a huge role in pair bonding. It is stimulated in numerous ways, including sex, birth, and breastfeeding. The ability of oxytocin to facilitate social bonding for human females in both marital and parenting relationships has been documented in a large body of previous research. A new study from Bar-Ilan University reveals that oxytocin administrated to fathers increases their parental...

In a world-first, researchers from the Australian Centre for Nanomedicine at the University of New South Wales (UNSW) in Sydney have developed a nanoparticle that could improve the effectiveness of chemotherapy for neuroblastoma by a factor of five. Neuroblastoma is an aggressive childhood cancer that often leaves survivors with lingering health problems due to the high doses of chemotherapy drugs required for treatment. Anything that can potentially reduce these doses is considered an...

Johns Hopkins team first identified biochemical clue to therapy in brain scans of people with MS Johns Hopkins researchers report the successful use of a form of MRI to identify what appears to be a key biochemical marker for cognitive impairment in the brains of people with multiple sclerosis (MS). In follow-up experiments on mice with a rodent form of MS, researchers were able to use an experimental compound to manipulate that same marker and dramatically improve learning and memory....

Hormone Helps Keep Married Men Away From Unknown Attractive Woman

Lawrence LeBlond for redOrbit.com - Your Universe Online It´s only natural that married men continue to check out other attractive women that happen to come into their field of view. Occasionally, some of these men also have a tendency to seek out these women and make contact. And some may even pursue these women further. But now, a new study published in Tuesday´s issue of the Journal of Neuroscience has uncovered a surprising new property of a hormone they say will keep...
