Study Gives Hope For A Potentially New PTSD Treatment
2013-06-08 08:16:57

Lee Rannals for redOrbit.com — Your Universe online Researchers writing in the journal Science Translational Medicine say they have discovered a potential new treatment for posttraumatic stress disorder (PTSD). The team from Emory University, University of Miami and Scripps Research Institute discovered a compound called SR-8993 that was able to reduce PTSD-like symptoms in mice after they are exposed to stress. The discovery could pave the way for a treatment given to people...

Scientists have proven that people use a different part of the brain to learn about social hierarchies than the part normally used for processing other types of information. Ultimate Memory developers incorporated this information into some of the memory-building exercises in the Ultimate Memory 2013 release. New York City, NY (PRWEB) June 04, 2013 One of the most basic of human instincts is survival, and successful survival includes learning who makes up social groups and how best to form...

During Puberty, The Brain Add News Cells
2013-03-05 05:03:51

redOrbit Staff & Wire Reports - Your Universe Online Two US neuroscientists have discovered new cells are added to a person´s brain when they go through puberty — a biological change designed to better equip growing boys and girls for the rigors of becoming adults. Previously, experts had believed the human brain maintained a set number of cells from birth through old age, but then studies demonstrated that new brain cells were formed in adults. Initially, it was believed...

A team of political scientists and neuroscientists has shown that liberals and conservatives use different parts of the brain when they make risky decisions, and these regions can be used to predict which political party a person prefers. The new study suggests that while genetics or parental influence may play a significant role, being a Republican or Democrat changes how the brain functions. Dr. Darren Schreiber, a researcher in neuropolitics at the University of Exeter, has been working...

How Does The Brain Process Fear?
2013-02-05 04:55:00

Connie K. Ho for redOrbit.com — Your Universe Online A new study from the University of Iowa (UI) recently found the amygdala, an almond-shaped area of the brain, is not the only part of the brain managing fear; other regions, such as the brainstem, the insular cortex and the diencephalon, also play a role. “This research says panic, or intense fear, is induced somewhere outside of the amygdala,” explained the senior author of the study John Wemmie, who serves as an...

Neuroscientists Locate Fear Memory In The Amygdala

April Flowers for redOrbit.com - Your Universe Online A noise in the dark, a rustle in the undergrowth; these are sounds likely to make an animal or a person stop sharply and be still, anticipating a predator. Freezing is part of the natural fear response, a reaction to a stimulus in the environment and part of how the brain decides whether to be afraid of it. A new study released by a neuroscience group at Cold Spring Harbor Laboratory (CSHL) examines how fear responses are learned,...

Following the birth of a child, new mothers may have an altered perception of stresses around them, showing less interest in threats unrelated to the baby. This change to the neuroendocrine circuitry could help the mothers adapt to the additional stress often accompanying newborns, say researchers from Indiana University's Kinsey Institute and the University of Zurich. When viewing disturbing images during the study, postpartum women reported less distress and demonstrated less activity in...

Having a drink after a stressful day at work may seem like a natural response for some, but can your neural circuits predict when a drink or two will become problem drinking? A study published in BioMed Central's open-access journal Biology of Mood & Anxiety Disorders suggests that may be the case. The study describes a highly novel mechanism predicting problem drinking in college students from fMRI data measuring individual differences in the functioning of reward and threat circuits in...

Meditation Has Lasting Emotional Benefits Says Study
2012-11-13 11:30:10

April Flowers for redOrbit.com - Your Universe Online Meditation has been part of the human experience for at least 5,000 years. Our first written records of the ancient art are found in Indian scriptures, called tantras. Around 2,500 years ago, Siddhartha Gautma, commonly called Buddha, began teaching meditation as a road to enlightenment. However, it wasn´t until the 1960s that Western professors and researchers began studying the effects of mediation in earnest. Participating in...

Stress During Infancy Affects Brain Development Of Females
2012-11-13 06:16:34

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University of Wisconsin-Madison recently discovered that early family stress during infancy could be related to changes that occur in the daily brain function and anxiety of teenage girls. The data was pooled from a population study that looked at the relationship between stress and the developmental pathway of the brain. For female infants who lived in homes with stressed out mothers, they were more likely...
