Research finding may accelerate development of treatments for PTSD

Scientists at Yerkes National Primate Research Center, Emory University have identified a drug that appears to make memories of fearsome events less durable in mice. [More]
Early life stress can have lasting negative impacts on the brain

Early life stress can have lasting negative impacts on the brain

For children, stress can go a long way. A little bit provides a platform for learning, adapting and coping. But a lot of it - chronic, toxic stress like poverty, neglect and physical abuse - can have lasting negative impacts. [More]
Tinnitus patients process emotions differently in brain from those with normal hearing

Tinnitus patients process emotions differently in brain from those with normal hearing

Patients with persistent ringing in the ears - a condition known as tinnitus - process emotions differently in the brain from those with normal hearing, researchers report in the journal Brain Research. [More]
Brain activation differences hint at developing course of bipolar disorder

Brain activation differences hint at developing course of bipolar disorder

Results of an activation likelihood estimation meta-analysis highlight the differences and similarities in brain activation between youths and adults with bipolar disorder. [More]
Children may benefit from targeted treatments specific to pediatric brain activity

Children may benefit from targeted treatments specific to pediatric brain activity

A new study from Bradley Hospital has found that bipolar children have greater activation in the right amygdala - a brain region very important for emotional reaction - than bipolar adults when viewing emotional faces. [More]

Study analyses link between childhood maltreatment and volume of cerebral grey matter

An international study has analysed the association between childhood maltreatment and the volume of cerebral grey matter, responsible for processing information. [More]
Amygdala alterations during childhood may influence development of anxiety problems

Amygdala alterations during childhood may influence development of anxiety problems

The amygdala is a key "fear center" in the brain. Alterations in the development of the amygdala during childhood may have an important influence on the development of anxiety problems, reports a new study in the current issue of Biological Psychiatry. [More]

Global scientists to discuss latest findings on diagnosis, causes and treatments of ASD

The International Society for Autism Research (INSAR), a scientific and professional organization devoted to advancing knowledge about autism spectrum disorders, convened more than 1700 researchers, delegates, autism specialists and students from 40 countries for the 13th Annual International Meeting for Autism Research (IMFAR), the world's largest scientific gathering on autism research, from May 15 through May 17 at the Atlanta Marriott Marquis in Atlanta, GA.

Psilocybin in magic mushroom inhibits negative emotions in brain, shows study

Psilocybin in magic mushroom inhibits negative emotions in brain, shows study

Emotions like fear, anger, sadness, and joy enable people to adjust to their environment and react flexibly to stress and strain and are vital for cognitive processes, physiological reactions, and social behaviour. [More]
Neuroinflammation levels higher in patients with chronic fatigue syndrome

Neuroinflammation levels higher in patients with chronic fatigue syndrome

Researchers at the RIKEN Center for Life Science Technologies, in collaboration with Osaka City University and Kansai University of Welfare Sciences, have used functional PET imaging to show that levels of neuroinflammation, or inflammation of the nervous system, are higher in patients with chronic fatigue syndrome than in healthy people.

Brain disconnect leaves teen brain less able to judge trustworthiness

Brain disconnect leaves teen brain less able to judge trustworthiness

Making a snap decision usually means following your initial reaction -- going with your gut. That intuitive feeling sprouts from the limbic system, the evolutionarily older and simpler part of the brain that affects emotion, behavior and motivation. [More]
Biological basis for visual hallucinations identified

Biological basis for visual hallucinations identified

Visual hallucinations in patients with schizophrenia may be caused by hyperconnectivity in a specific area of the brain, say researchers. [More]

Study: Musical aptitude is affected by a combination of genes involved in auditory pathway

Multiple regions in the human genome are reported to be linked to musical aptitude, according to a study published this week in Molecular Psychiatry. [More]
Parkinson's patients under risk of developing dementia can be identified quickly, say researchers

Parkinson's patients under risk of developing dementia can be identified quickly, say researchers

It may now be possible to identify the first-stage Parkinson's patients who will go on to develop dementia, according to a study conducted at the Institut universitaire de gériatrie de Montréal by Dr. Oury Monchi, PhD, and his postdoctoral student, Dr. Alexandru Hanganu, MD, PhD, both of whom are affiliated with Université de Montréal.

Music does not speak to everyone

Music does not speak to everyone

Although it is not associated with any apparent biological advantagess or useful value (such as money), music is ranked among the highest sources of pleasure. Music's important role in our society and culture has led to the assumption that its ability to induce pleasure is universal. However, this assumption has never been empirically tested. [More]
Far-reaching neurons connect amygdala with fear response center to control behavior

Far-reaching neurons connect amygdala with fear response center to control behavior

Fear is primal. In the wild, it serves as a protective mechanism, allowing animals to avoid predators or other perceived threats. For humans, fear is much more complex. A normal amount keeps us safe from danger. But in extreme cases, like post-traumatic stress disorder (PTSD), too much fear can prevent people from living healthy, productive lives. [More]
Chronic stress generates long-term changes in brain that lead to mental problems

Chronic stress generates long-term changes in brain that lead to mental problems

University of California, Berkeley, researchers have shown that chronic stress generates long-term changes in the brain that may explain why people suffering chronic stress are prone to mental problems such as anxiety and mood disorders later in life. [More]
