Incidental Anger, Contempt And Disgust Lead To Hostility
Individuals experiencing anger, contempt and disgust are more likely to act and behave in a hostile manner toward those they disagree with, new research from San Francisco State University shows.

Sensorimotor Simulation Contributes To Facial Expression Recognition
Smile! It makes everyone in the room feel better because they, consciously or unconsciously, are smiling with you. Growing evidence shows that an instinct for facial mimicry allows us to empathize with and even experience other people’s feelings. If we can’t mirror another person’s face, it limits our ability to read and properly react to…
The Difference Between Narcissism And Self-esteem

Despite the widely held view among psychologists that narcissists have an inflated,…
Latent Effects Of Early Adolescent Marijuana Use On Cortex Architecture
The age at which an adolescent begins using marijuana may affect typical brain development, according to researchers at the Center for BrainHealth at The University of Texas at Dallas. In a paper recently published, scientists describe how marijuana use, and the age at which use is initiated, may adversely alter brain structures that underlie higher…
How Cerebral Cortex Malformations Link To Epilepsy Occurrence
Why does a structural irregularity in the temporal lobe make humans more susceptible to epileptic seizures? Experts have been searching for the answer to this question for a long time. A group of scientists at the Freiburg University Medical Center consisting of members of the University of Freiburg’s Cluster of Excellence Brain Links-Brain Tools has…
How Mind-controlled Bionic Devices Could Help Quadriplegics Walk
The development of “mind-controlled” bionic devices moved another step closer today with the publication of a Nature Biotechnology paper describing how a tiny, 3cm-long stent containing 12 electrodes could one day help people living with spinal cord injury to walk with the power of thought. The device, called the “stentrode”, is inserted into the jugular…
Vasopressin Promotes Cooperation In Risky Situations
A hormone that seems to promote monogamy and parenting in people may also make us more likely to cooperate with others, even in risky situations. Research in rodents shows while the hormone, called AVP (arginine vasopressin), promotes bonding, it also boosts aggression in males. Says Colin Camerer, a professor of behavioural economics at Caltech; “Part…
Meditation Plus Aerobic Exercise Helps Reduce Depression
A new study has found that the mind-body combination of meditation and aerobic exercise, done twice a week for only two months, reduced the depression symptoms for a group of students by 40 percent. Says Brandon Alderman, lead author of the research study: “We are excited by the findings because we saw such a meaningful…
