Confirmation of neurobiological origin of attention-deficit disorder The neurobiological origin of attention-deficit disorder (ADD), a syndrome whose causes are poorly understood, has just been confirmed by a study carried out on mice. Researchers have identified a cerebral structure, the superior colliculus, where hyperstimulation causes behavior modifications similar to those of some patients who suffer from ADD. Their work also shows noradrenaline accumulation in the affected area, shedding light on this chemical mediator having a role in attention disorders.

Confirmation Bias - Psychology Definition of the Week Definition: When we are making a decision about an issue, we often like to believe that we carefully balance the existing evidence and formulate an opinion that is balanced, logical, and impartial. The reality is that we often fall victim to a problem known as the confirmation bias. This involves only paying attention to information that supports our current point of view, or even interpreting information in such as way that it upholds our existing beliefs. In other words, we look for evidence that supports our opinions and ignore information that conflicts with what we already believe to be true....Read Full Post

But there are some ways of fighting that aren’t as constructive, in fact they’re down right dirty and can impact your relationship negatively. Here […]
How the brain pays attention: Identifying regions of the brain dealing with object-based, spacial attention A brain circuit that's key to shifting our focus from one object to another has been identified by neuroscientists. The new findings suggest that there are two types of attention that have similar mechanisms involving related brain regions: object-based attention, and spatial attention. In both cases, the prefrontal cortex -- the control center for most cognitive functions -- appears to take charge of the brain's attention and control relevant parts of the visual cortex, which receives sensory input.
Finding the target: How timing is critical in establishing an olfactory wiring map A developmental window during which olfactory neurons of newborn mice can form a proper wiring map has been identified by researchers. They show that if incorrect neuronal connections are maintained after this period, renewing cells will also be mis-wired. The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays only a single type of receptor and all neurons with the same receptors are connected to the same spot, a glomerulus, in the brain.
Researchers search for earliest roots of psychiatric disorders A single molecular mechanism in the developing brain has been identified that sheds light on how cells may go awry when exposed to a variety of different environmental insults. The findings suggest that different types of stressors prenatally activate a single molecular trigger in brain cells that may make exposed individuals susceptible to late-onset neuropsychiatric disorders.
Brainy courage of the rainbowfish The boldest black-lined rainbowfish are those that are born in the wild. Also more fearless are those that analyze information with both sides of their brains. The preference to analyze and react to information with either the left or right hemisphere of the brain is called cerebral lateralization, and is widespread among vertebrates. Lateralization is seen in the preference of humans or parrots to use one hand or claw over the other or to always turn to the same side when moving around objects.

Head injuries can make children loners Kids three years after an initial head incident were found to have lingering injury in the brain's right frontal lobe, which is associated with lower social competence (participation in groups, number of friends, etc.), a new study finds. The study also suggests that therapy designed to improve working memory might 'treat' the social difficulties.
Neurofinance study confirms that financial decisions are made on an emotional basis The willingness of decision makers to take risks increases when they play games of chance with money won earlier.  Risk taking also rises when they have the opportunity to compensate for earlier losses by breaking even.
