Study shows noticeable differences in brain function across the day for older adults

Older adults who are tested at their optimal time of day (the morning), not only perform better on demanding cognitive tasks but also activate the same brain networks responsible for paying attention and suppressing distraction as younger adults, according to Canadian researchers. [More]
UCSF researchers identify novel molecular features within the developing human brain

UCSF researchers identify novel molecular features within the developing human brain

UC San Francisco researchers have identified cells' unique features within the developing human brain, using the latest technologies for analyzing gene activity in individual cells, and have demonstrated that large-scale cell surveys can be done much more efficiently and cheaply than was previously thought possible.

Persons with ASD have trouble in noticing their movement imitated by others

Persons with ASD have trouble in noticing their movement imitated by others

A Japanese research group led by Prof Norihiro Sadato, a professor of the National Institute for Physiological Sciences (NIPS), National Institutes of Natural Sciences (NINS), has found that people with autism spectrum disorders (ASD) have decreased activity in an area in the brain critical for understanding if his/her movement was imitated by others.

Children with fetal alcohol spectrum disorders show weaker brain activation

Children with fetal alcohol spectrum disorders show weaker brain activation

In the first study of its kind, Prapti Gautam, PhD, and colleagues from The Saban Research Institute of Children's Hospital Los Angeles found that children with fetal alcohol spectrum disorders (FASD) showed weaker brain activation during specific cognitive tasks than their unaffected counterparts.

Acupuncture at Waiguan can activate several brain regions in patients with ischemic stroke

Acupuncture at Waiguan can activate several brain regions in patients with ischemic stroke

Both acupuncture at Waiguan (SJ5) and sham acupuncture can activate/deactivate several brain regions in patients with ischemic stroke, but there are some difference in Brodmann areas 4, 6, 8, Brodmann areas 7, 39, 40, Brodmann areas 18, 19, 22 and Brodmann areas 13, 24, 32, 28. [More]

UC Davis researcher receives NSSEFF grant to advance new work on learning and memory

Professor Charan Ranganath of the UC Davis Center for Neuroscience and Department of Psychology has received a National Security Science and Engineering Faculty Fellowship from the U.S. Department of Defense. [More]
Scientists unravel neural circuit that could play important role in autism

Scientists unravel neural circuit that could play important role in autism

The insular cortex is an integral "hub", combining sensory, emotional and cognitive content. Not surprisingly, alterations in insular structure and function have been reported in many psychiatric disorders, such as anxiety disorders, depression, addiction and autism spectrum disorders (ASD). [More]
Prolonged exposure to loud noise alters how the brain processes speech

Prolonged exposure to loud noise alters how the brain processes speech

Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists at The University of Texas at Dallas. [More]
Alterations to single gene could predict risk of suicide attempt

Alterations to single gene could predict risk of suicide attempt

Johns Hopkins researchers say they have discovered a chemical alteration in a single human gene linked to stress reactions that, if confirmed in larger studies, could give doctors a simple blood test to reliably predict a person's risk of attempting suicide. [More]
New electrical pattern in brains predicts how well individual animals fare in stressful situations

New electrical pattern in brains predicts how well individual animals fare in stressful situations

Some people can handle stressful situations better than others, and it's not all in their genes: Even identical twins show differences in how they respond. [More]
Brains of autistic kids are relatively inflexible at switching from rest to task performance

Brains of autistic kids are relatively inflexible at switching from rest to task performance

The brains of children with autism are relatively inflexible at switching from rest to task performance, according to a new brain-imaging study from the Stanford University School of Medicine. [More]
Parallel brain circuits associated with opposing emotional reactions

Parallel brain circuits associated with opposing emotional reactions

People choosing between two or more equally positive outcomes experience paradoxical feelings of pleasure and anxiety, feelings associated with activity in different regions of the brain, according to research led by Amitai Shenhav, an associate research scholar at the Princeton Neuroscience Institute at Princeton University.

Melatonin has protective effects on traumatic brain injury-induced cerebral cortex

Melatonin has protective effects on traumatic brain injury-induced cerebral cortex

Traumatic brain injury can cause post-traumatic neurodegenerations with an increase in reactive oxygen species and reactive oxygen species-mediated lipid peroxidation. Melatonin, a non-enzymatic antioxidant and neuroprotective agent, has been shown to counteract oxidative stress-induced pathophysiologic conditions like cerebral ischemia/reperfusion injury, neuronal excitotoxicity and chronic inflammation.

GW researcher awarded SFARI grant for autism research

GW researcher awarded SFARI grant for autism research

The link between autism and disrupted brain development is an essential part of the puzzle of the disease, and is largely unknown. However, thanks to funding from the Simons Foundation Autism Research Initiative, George Washington University researcher Anthony-Samuel LaMantia, Ph.D. may be able to offer truly integrative and in-depth answers to these key questions in the field of autism research.

Astrocytes may be behind mental disorders, new research reveals

Astrocytes may be behind mental disorders, new research reveals

Astrocytes, the cells that make the background of the brain and support neurons, might be behind mental disorders such as depression and schizophrenia, according to new research by a Portuguese team from the ICVS at the University of Minho. [More]

Trying harder makes it more difficult to learn certain aspects of language, shows study

When it comes to learning languages, adults and children have different strengths. Adults excel at absorbing the vocabulary needed to navigate a grocery store or order food in a restaurant, but children have an uncanny ability to pick up on subtle nuances of language that often elude adults. [More]
Study analyses whether connectivity of infant's brain is related to children's impulsiveness

Study analyses whether connectivity of infant's brain is related to children's impulsiveness

Researchers from the University of Murcia have studied the changes in the brain that are associated with impulsiveness, a personality trait that causes difficulties in inhibiting a response in the face of a stimulus and leads to unplanned actions without considering the negative consequences.

Researchers explore brain estrogens to mitigate learning and memory problems

Researchers explore brain estrogens to mitigate learning and memory problems

New studies being launched by neurobiologist Luke Remage-Healey at the University of Massachusetts Amherst will investigate how estrogens produced in the brains of young birds enhance their ability to learn songs during a critical window during development. [More]

Research leads to better understanding of neurodegenerative, neurodevelopmental diseases

Throughout our lives, our brains adapt to what we learn and memorise. The brain is indeed made up of complex networks of neurons and synapses that are constantly re-configured. [More]
Findings fuel idea that processes of active movement and sensory processing are connected

Findings fuel idea that processes of active movement and sensory processing are connected

A new study by researchers at the University of Oregon published today in the journal Neuron describes a brainstem circuit in mice that may help explain how active movement impacts the way the brain processes sensory information. [More]
