Drugs and the Disorganized Mind


How cannabis causes 'cognitive chaos' in the brain

ScienceDaily (2011-10-25) -- Cannabis use is associated with disturbances in concentration and memory. New research by neuroscientists in the UK has found that brain activity becomes uncoordinated and inaccurate during these altered states of mind, leading to neurophysiological and behavioral impairments reminiscent of those seen in schizophrenia. ... > read full article

The Brain Thinks Dreams Are Real


Scientists measure dream content for the first time: Dreams activate the brain in a similar way to real actions

ScienceDaily (2011-10-28) -- The ability to dream is a fascinating aspect of the human mind. However, how the images and emotions that we experience so intensively when we dream form in our heads remains a mystery. Up to now it has not been possible to measure dream content. Scientists in Germany have now succeeded, for the first time, in analyzing the activity of the brain during dreaming. ... > read full article

Ever Heard of Drunkorexia? Another Twist on Addictive Consumption


Drunkorexia: A recipe for disaster

ScienceDaily (2011-10-17) -- It is well-known that eating disorders are common among teens and college students. Heavy alcohol consumption is another well-known unhealthy habit of this age group. A new study shows that when college students combine these two unhealthy habits, their long-term health may be affected. "Drunkorexia" is a new term coined by the media to describe the combination of disordered eating and heavy alcohol consumption... read full article

Do Schizophrenics Really Hear Voices...Maybe?


Schizophrenia genetics linked to disruption in how brain processes sound

ScienceDaily (2011-10-14) -- What links genetic differences to changes in altered brain activity in schizophrenia is not clear. Now, three labs have come together using electrophysiological, anatomical, and immunohistochemical approaches -- along with a unique high-speed imaging technique -- to understand how schizophrenia works at the cellular level, especially in identifying how changes in the interaction between different types of nerve cells leads to symptoms of the disease. ... > read full article

Brining A Whole New (Other) Meaning to "Businesswomen" Around The World

The Economist's Schumpeter column, which I often vehemently disagree with for its extreme opinions, hit a home run last week with The Daughter Also Rises: Women Are Storming Emerging-World Boardrooms. It chronicles the sagas of numerous female "businesswomen" (which in Russia has a less than flattering double meaning...who knew? See the article!) in emerging markets around the world and the painful but steady shifts that working, educated even millionaire and billionaire women are making in places where culture has stood firmly to dangerous and lethal beliefs about what half the population can and can't do!

Insomniac Blues! Lack of Sleep Kills Productivity


Insomnia costing US workforce $63.2 billion a year in lost productivity, study shows

ScienceDaily (2011-09-02) -- Insomnia is costing the average US worker 11.3 days, or $2,280 in lost productivity every year, according to a new study considered to be more accurate than previous estimates. Researchers hope such numbers will prompt the implementation of screening and treatment programs for employees. Because insomnia is not considered an illness -- the kind that results in lost days at work -- employers tend to ignore its consequences. ... > read full article

Alarm Bells in the Brain: Alcohol Indeed Turns That Ringing Down


Alcohol dulls brain 'alarm' that monitors mistakes, study finds

ScienceDaily (2011-09-02) -- Most people have witnessed otherwise intelligent people doing embarrassing or stupid things when they are intoxicated, but what specifically happens in the brain to cause such drunken actions? A new study testing alcohol's effects on brain activity finds that alcohol dulls the brain "signal" that warns people when they are making a mistake, ultimately reducing self control. ... > read full article

Beating the Young Whipper Snappers: Decision Making Does Get Better With Age


Older adults are better at decision-making than young adults

ScienceDaily (2011-08-23) -- We make decisions all our lives -- so you'd think we'd get better and better at it. Yet research has shown that younger adults are better decision-makers than older ones. Some psychologists, puzzled by these findings, suspected the experiments were biased toward younger brains. ... > read full article

I Love "Aha" Moments: How the Brain Makes Predictions


Everyday 'clairvoyance:' How your brain makes near-future predictions

ScienceDaily (2011-08-18) -- Every day we make thousands of tiny predictions -- when the bus will arrive, who is knocking on the door, whether the dropped glass will break. Now, in one of the first studies of its kind, researchers are beginning to unravel the process by which the brain makes these everyday prognostications. ... > read full article

Talking and Listening Processed in the Same Region of the Brain fMRI Reveals


Speaking and understanding speech share the same parts of the brain

ScienceDaily (2011-08-16) -- The brain has two big tasks related to speech: making it and understanding it. Psychologists and others who study the brain have debated whether these are really two separate tasks or whether they both use the same regions of the brain. Now, a new study finds that speaking and understanding speech share the same parts of the brain, with one difference: we don't need the brain regions that control the movements of lips, teeth, and so on to understand speech. ... > read full article

Why Eating is Fun: Thank the Hormone Ghrelin


The Neurobiology Behind Why Eating Feels So Good

ScienceDaily (2006-10-19) -- The need to eat is triggered by the hormone ghrelin. Ghrelin is produced in the gut and triggers the brain to promote eating, but it remains to be determined precisely how ghrelin affects different parts of the brain. A new study shows that in mice and rats, ghrelin triggers the same neurons as delicious food, sexual experience, and many recreational drugs; that is, neurons that provide the sensation of pleasure and the expectation of reward. ... > read full article
