Empathy is unusual in the animal kingdom. So empathy must have had some major survival benefits for it to have evolved. What might those benefits have been? Empathy seems to have evolved in three major steps. First, among vertebrates, birds and mammals developed ways of rearing their young, plus forms of pair bonding – sometimes for life.
Depression is actually defined by specific clinical symptoms such as sadness, difficulty to experience pleasure, and sleep problems that are present for at least two weeks with impairment of psychosocial functioning. These symptoms guide the physician to make a diagnosis and to select antidepressant treatment such as drugs or psychotherapy.
Since the 1980s, a high EEG abnormality rate has been reported for patients with panic disorder. However, how the EEG abnormalities are related to the clinical features and pathology of these patients has yet to be clarified. On the other hand, the risk of diagnosing panic disorder as epilepsy has been pointed out. In this study, researchers investigated whether or not EEG abnormalities are related to the 13 symptoms in the DSM-IV criteria for a diagnosis of panic attacks.

Alcohol dependence (AD) has negative effects on cognitive processes such as memory. Metamemory refers to the subjective knowledge that people have of their own cognitive processing abilities, such as their monitoring and control of memory. A new study has found that AD has a negative impact on both episodic memory as well as metamemory. Results will be published in the November 2010 issue of Alcoholism: Clinical & Experimental Research.
A group of “professional couch potatoes,” as one researcher described them, has proven that even moderate exercise – in this case walking at one’s own pace for 40 minutes three times a week – can enhance the connectivity of important brain circuits, combat declines in brain function associated with aging and increase performance on cognitive tasks.
Scientists at Harvard University have found that humans can make difficult moral decisions using the same brain circuits as those used in more mundane choices related to money and food. These circuits, also found in other animals, put together two critical pieces of information: How good or bad are the things that might happen? What are the odds that they will happen, depending on one’s choice? The results suggest that complex moral decisions need not rely on a specific “moral sense.”
There is still much that is unknown about autism spectrum disorders, but a University of Nevada, Reno psychologist has added to the body of knowledge that researchers around the world are compiling to try to demystify, prevent, and treat the mysterious condition. This research was published recently in the journal, Brain Research.
UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug. The findings were published in the journal Neuropsychopharmacology.
Whether it is sports, poker, or the high-stakes world of business, there are those who always find a way to win when there is money on the table. Now, for the first time, psychology researchers at Washington University in St. Louis are unraveling the workings of a novel brain network that may explain how these “money players” manage to keep their heads in the game. The results are published in the Journal of Neuroscience.
A new study by researchers at Albert Einstein College of Medicine of Yeshiva University has provided concrete evidence that children with autism spectrum disorders (ASD) process sensory information such as sound, touch, and vision differently than typically developing children. The results appear in the August 17 online issue of Autism Research. Included in this report is a video interview with the lead researcher who explains these results.
I heard a story once about a Native American elder who was asked how she had become so wise, so happy, and so respected. She answered: “In my heart, there are two wolves: a wolf of love and a wolf of hate. It all depends on which one I feed each day.”
It is unavoidable: breakdowns in brain connections slow down our physical response times as we age, a new study suggests. This slower reactivity is associated with an age-related breakdown in the corpus callosum, a part of the brain that acts as a dam during one-sided motor activities to prevent unwanted connectivity, or cross-talk, between the two halves of the brain, said Rachael Seidler, associate professor in the University of Michigan School of Kinesiology and Department of Psychology, and lead study author.
