Study sheds new light on perception and memory of human brain

The human brain can select relevant objects from a flood of information and edit out what is irrelevant. It also knows which parts belong to a whole. [More]
ULB researchers test therapeutic potential of cortical neurons developed in laboratory

ULB researchers test therapeutic potential of cortical neurons developed in laboratory

Researchers at the ULB - IRIBHM and ULB Neuroscience Institute - have tested the therapeutic potential of cortical neurons generated at the laboratory, by transplantation in the brains of adult mice. [More]
Multimodal approach to distinguish people with autism spectrum disorder

Multimodal approach to distinguish people with autism spectrum disorder

In an ancient Indian parable, a group of blind men touches different parts of a large animal to find what it is. Only when they share the descriptions of an ear, tail, trunk and leg do they know it is an elephant. [More]
Possible therapies to address cognitive symptoms in individuals with schizophrenia

Possible therapies to address cognitive symptoms in individuals with schizophrenia

By studying specially bred mice with specific developmental and cognitive traits resembling those seen in schizophrenia, UC San Francisco researchers have provided new evidence that abnormal rhythmic activity in particular brain cells contributes to problems with learning, attention, and decision-making in individuals with that disorder.

Study shows how mutations that cause Alzheimer's disease lead to neurodegeneration, dementia

Study shows how mutations that cause Alzheimer's disease lead to neurodegeneration, dementia

A study from researchers at Massachusetts General Hospital and Brigham and Women's Hospital reveals for the first time exactly how mutations associated with the most common form of inherited Alzheimer's disease produce the disorder's devastating effects. [More]
Common antidepressant medications not helpful for people with mood, anxiety disorders

Common antidepressant medications not helpful for people with mood, anxiety disorders

Studies indicate that the majority of people with mood and anxiety disorders who receive the most commonly prescribed class of antidepressant medications, Selective Serotonin Reuptake Inhibitors or SSRI's, are not helped by these medications. SSRIs are designed to increase serotonin, a neurotransmitter in the brain that is key to maintenance of mood. [More]
Neuroscientists find new pathway that allows several brain areas communicate within striatum

Neuroscientists find new pathway that allows several brain areas communicate within striatum

Carnegie Mellon University neuroscientists have identified a new pathway by which several brain areas communicate within the brain's striatum. [More]
Brain scientists map changes in communication between nerve cells in rats

Brain scientists map changes in communication between nerve cells in rats

Lights, sound, action: we are constantly learning how to incorporate outside sensations into our reactions in specific situations. In a new study, brain scientists have mapped changes in communication between nerve cells as rats learned to make specific decisions in response to particular sounds. The team then used this map to accurately predict the rats' reactions. These results add to our understanding of how the brain processes sensations and forms memories to inform behavior. [More]
Study shows physical similarities, differences between extrovert types in the brain

Study shows physical similarities, differences between extrovert types in the brain

Everyday experience and psychological studies alike tell us that there are two different types of extroverts: The gregarious "people-persons" who find reward in sharing affection and affiliation with others, and the ambitious "go-getters" who flash those bright-white smiles in their pursuit of achievement and leadership agendas.

Carnegie Mellon study identifies intermediary neuron system that acts as synaptic cloaking device

Carnegie Mellon study identifies intermediary neuron system that acts as synaptic cloaking device

Neuroscientists believe that the connectome, a map of each and every connection between the millions of neurons in the brain, will provide a blueprint that will allow them to link brain anatomy to brain function. But a new study from Carnegie Mellon University has found that a specific type of neuron might be thwarting their efforts at mapping the connectome by temporarily cloaking the synapses that link a wide field of neurons.

New study shows how anterior cingulate cortex can be stimulated to control pain

New study shows how anterior cingulate cortex can be stimulated to control pain

A new study by a University of Texas at Arlington physics team in collaboration with bioengineering and psychology researchers shows for the first time how a small area of the brain can be optically stimulated to control pain. [More]

New study finds that wandering mind can impart distinct cognitive advantage

Does your mind wander when performing monotonous, repetitive tasks? Of course! But daydreaming involves more than just beating back boredom. In fact, according to a new study published in the Proceedings of the National Academy of Sciences, a wandering mind can impart a distinct cognitive advantage. [More]
Broca's Area Is The Brain's Scriptwriter, Shaping Speech, Study Finds

Broca's Area Is The Brain's Scriptwriter, Shaping Speech, Study Finds

What is happening in the brain of an actor reciting Hamlet's "to be or not to be" soliloquy or of the person next to you at lunch saying, "Please pass the salt"? For 150 years, scientists have known that a brain region called Broca's area plays a key role in speech production, but exactly what it does and how it does it have been a mystery. [More]
Research may lead to future medical treatments for children with neurodevelopmental problems

Research may lead to future medical treatments for children with neurodevelopmental problems

Children born with a DNA abnormality on chromosome 16 already linked to neurodevelopmental problems show measurable delays in processing sound and language, says a study team of radiologists and psychologists. [More]
New discovery could lead to potential treatment for preventing blindness

New discovery could lead to potential treatment for preventing blindness

Scientists have made a major new discovery detailing how areas of the brain responsible for vision could potentially adapt to injury or trauma and ultimately prevent blindness. [More]
Neuroscientist to discuss teenage brain development at AAAS meeting in California

Neuroscientist to discuss teenage brain development at AAAS meeting in California

Teenage exploration and risk taking could be explained by dramatic changes in the brain that allow elaborate planning and are driven by the need for immediate reward, according to a University of Pittsburgh neuroscientist who will be talking about her research in a panel discussion and press briefing at the American Association for the Advancement of Science annual meeting, Feb. 13 to 16, in San Jose, Calif.

Study shows amyloid formation may link type 2 diabetes and Alzheimer disease

Study shows amyloid formation may link type 2 diabetes and Alzheimer disease

The pathological process amyloidosis, in which misfolded proteins (amyloids) form insoluble fibril deposits, occurs in many diseases, including Alzheimer disease (AD) and type 2 diabetes mellitus (T2D). [More]
New Penn Medicine study reveals how sleep deprivation increases intake of fat

New Penn Medicine study reveals how sleep deprivation increases intake of fat

Experts have warned for years that insufficient sleep can lead to weight gain. A new Penn Medicine study found that not only do we consume more food following a night of total sleep deprivation, but we also we consume more fat and less carbohydrates and a region of the brain known as the salience network is what may lead us to eat more fat.

Mindfulness training can influence health via stress reduction pathways

Mindfulness training can influence health via stress reduction pathways

Over the past decade, there have been many encouraging findings suggesting that mindfulness training can improve a broad range of mental and physical health problems. Yet, exactly how mindfulness positively impacts health is not clear. [More]

Adolescents meth abusers suffer greater alterations in their brain than adult drug abusers

Adolescents who chronically use methamphetamine suffer greater and more widespread alterations in their brain than adults who chronically abuse the drug-and damage is particularly evident in a part of the brain believed to control the "executive function," researchers from the University of Utah and South Korea report.
