A new study by Valsamma Eapen and colleagues from University of New South Wales, Sydney, Australia found that women with low oxytocin levels in the postpartum have a history of bad mother-to-daughter bonding.
[Review] There is general agreement that excessive activation of N-methyl-D-aspartate (NMDA) receptors plays a key role in mediating at least some aspects of synaptic dysfunction in several central nervous system disorders. On this view, in the last decades, research focused on the discovery of different compounds able to reduce NMDA receptor activity, such as classical and/or subunit-specific antagonists. However, the increasing body of knowledge on specific signaling pathways downstream NMDA receptors led to the identification of new pharmacological targets for NMDA receptor-related pathological conditions. Moreover, besides over-activation, several studies indicated that also abnormal NMDA receptor trafficking, resulting in the modification of the receptor subunit composition at the synapse, has a major role in the pathogenesis of several brain disorders. For this reason, the discovery of the molecular mechanisms regulating the abundance of synaptic versus extra-synaptic NMDA receptors as well as the activation of the specific signaling pathways downstream the different NMDA receptor subtypes is needed for the development of novel therapeutic approaches for NMDA receptor-dependent synaptic dysfunction.

Oxytocin (OT) was once only thought to act on smooth muscle of either the breast, uterus and females; or the vas deferens of males for spem transport. Now we associate OT to a role in bonding, love and, perhaps, morality. Why such an enormously strident leap? It makes sense that a mother would use OT to mediate bond-forming with the child because nature is parsimonious with its chemicals, often using the same molecule for physiologic and psychologic purposes if they are related to the same hapistance. Hence, all the recent other attributes of OT is more of the same economy of purpose despite having a vas deferens in the objectives to be achieved.

"With the 2012 elections just months away, people are now, more than ever before, thinking about leadership. What works? What doesn't work? What should we look for in leaders and how do we know if one is going to be more successful than another?...Neuroscience research is beginning to help fill in the gaps. While we are nowhere near being able to scan a leader's brain while running a meeting (even if that was a good idea), we can study some of the building blocks of what leaders do -- making decisions under pressure, solving complex problems, negotiating a transaction or trying to persuade others. There have been some big surprises in the research. Here are just a few."
Not only can the brain learn new tricks, but it can also change its structure and function--even in old age (RT @JosieJosieg: The Brain: How The Brain Rewires Itself - #creativity #neuroscience via @CreatvEmergence
Our amazing brain performs harmonious functions and peculiar actions that might seem counterintuitive. What tricks make us think it's okay to cheat or steal? Are we in control of our own decisions? Why do our brains misjudge what will make us happy?
Building on their earlier work that suggested people who meditate have less age-related atrophy in the brain's white matter, a new study found that meditation appeared to help preserve the brain's gray matter, the tissue that contains neurons.
Two thirds of the population believes a myth that has been propagated for over a century: that we use only 10% of our brains. Hardly! Our neuron-dense brains have evolved to use the least amount of energy while carrying the most information possible -- a feat that requires the entire brain. Richard E. Cytowic debunks this neurological myth (and explains why we aren’t so good at multitasking).
The ability to manage your emotions and remain calm under pressure has a direct link to your performance. TalentSmart has conducted research with more than a million people, and we’ve found that 90% of top performers are skilled at managing their emotions in times of stress in order to remain calm and in control.
The tricky thing about stress (and the anxiety that comes with it) is that it’s an absolutely necessary emotion. Our brains are wired such that it’s difficult to take action until we feel at least some level of this emotional state. In fact, performance peaks under the heightened activation that comes with moderate levels of stress. As long as the stress isn’t prolonged, it’s harmless.

Brain aging is the number one cause of disease, disability, and death in the elderly. By helping to slow brain aging, we trigger a cascade of beneficial effects throughout the body which keep us strong, healthy, and youthful.
Gerald P. Kozlowski's insight:
The brain is like a muscle. It requires good diet, oxygen and exercise to be maintained at peak levels. Never overestimate the requirements needed for your heads' athletic activities of learning, thinking and memory. Problem solving in the right environment leads to a better, more robust brain.
About my Brain official website, bringing together Neuroscience, business and the arts..."Neuroscience”, is a buzzword that has now become part of our daily vocabulary. Every day, news about the workings of our brains is being spread throughout the world. With the emergence of measurement techniques such as neuro-imaging, scientists have recently been able to study the intricacies of our nervous system, addressing complex questions such as the way we function as humans, how we make decisions and how we interact with our environment. One of the branches within the neuroscience field that is now attracting attention is “social cognitive neuroscience”, essentially an interdisciplinary field devoted to the understanding of how biological systems implement social processes and behaviour. In practical terms, learning about neuroscience and how each of our brains work, can help us to understand our actions and how we react. By doing so, we can be more mindful, productive and ultimately we can maintain our health and develop great relationships. Neuroscience, in itself is not a solution to problems, but it can certainly shed some light into how we can manage ourselves and others in every aspect of our lives."
"Studying an object as complex as the brain may seem almost futile. The brain's billions of neurons resemble trees of many species and come in many fantastic shapes. Only the most determined explorers can hope to capture a glimpse of this forest's interior, and even they see little, and see it poorly. It's no wonder that the brain remains an enigma. My audience was curious about brains that malfunction or excel, but even the humdrum lacks explanation. Every day we recall the past, perceive the present, and imagine the future. How do our brains accomplish these feats? It's safe to say that nobody really knows."
