Urgency breeds aggression in schizophrenia patients

Urgency breeds aggression in schizophrenia patients

Increased urgency is a major contributor to aggression in patients with schizophrenia, suggests research published in The American Journal of Psychiatry. [More]
Scientists develop new method to get clearer picture of how drug abuse affects the brain

Scientists develop new method to get clearer picture of how drug abuse affects the brain

One thing leads to another, especially in research. When Stony Brook University School of Medicine scientists developed a new method to measure how cocaine disrupts blood flow in the brains of mice, doctors and researchers got a way to form a clearer picture of how drug abuse affects the brain.

New research illustrates how fear arises in the brain

New research illustrates how fear arises in the brain

An estimated 8% of Americans will suffer from post traumatic stress disorder (PTSD) at some point during their lifetime. Brought on by an overwhelming or stressful event or events, PTSD is the result of altered chemistry and physiology of the brain. [More]
Brain stimulation increases cravings for high-calorie foods, shows study

Brain stimulation increases cravings for high-calorie foods, shows study

Magnetic stimulation of a brain area involved in "executive function" affects cravings for and consumption of calorie-dense snack foods, reports a study in the September issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.

New study measures neurodevelopment in schizophrenia

New study measures neurodevelopment in schizophrenia

Schizophrenia is generally considered to be a disorder of brain development and it shares many risk factors, both genetic and environmental, with other neurodevelopmental disorders such as autism and intellectual disability. [More]

Brain structure 'significantly predictive' of individual risk attitudes

There is a link between our brain structure and our tolerance of risk, new research suggests. [More]
Different regions of brain help to visually locate objects relative to one's own body

Different regions of brain help to visually locate objects relative to one's own body

Serena Williams won her third consecutive US Open title a few days ago, thanks to reasons including obvious ones like physical strength and endurance. But how much did her brain and its egocentric and allocentric functions help the American tennis star retain the cup? [More]
People with multiple sclerosis lose myelin in gray matter

People with multiple sclerosis lose myelin in gray matter

People with multiple sclerosis (MS) lose myelin in the gray matter of their brains and the loss is closely correlated with the severity of the disease, according to a new magnetic resonance imaging (MRI) study. [More]
New way to preserve flexibility and resilience of the brain

New way to preserve flexibility and resilience of the brain

As Alzheimer's disease progresses, it kills brain cells mainly in the hippocampus and cortex, leading to impairments in "neuroplasticity," the mechanism that affects learning, memory, and thinking. [More]
Sex hormone that helps protect females from stroke may also reduce risk of autism, say scientists

Sex hormone that helps protect females from stroke may also reduce risk of autism, say scientists

The same sex hormone that helps protect females from stroke may also reduce their risk of autism, scientists say. [More]
Researchers reveal how distinct areas of frontal lobes are critical for person's ability to learn

Researchers reveal how distinct areas of frontal lobes are critical for person's ability to learn

Until the last few decades, the frontal lobes of the brain were shrouded in mystery and erroneously thought of as nonessential for normal function-hence the frequent use of lobotomies in the early 20th century to treat psychiatric disorders. [More]
Aberrant reward processing likely to precede bipolar symptom onset

Aberrant reward processing likely to precede bipolar symptom onset

Healthy children who have a parent with bipolar disorder show altered brain activation during reward processing, research shows. [More]
Findings could lead to improved treatments for stroke, other brain injuries

Findings could lead to improved treatments for stroke, other brain injuries

Learning a new skill is easier when it is related to ability that we already possess. For example, a trained pianist might learn a new melody more easily than learning how to hit a tennis serve. [More]

Brain's motor cortex can directly turn down hearing

When we want to listen carefully to someone, the first thing we do is stop talking. The second thing we do is stop moving altogether. This strategy helps us hear better by preventing unwanted sounds generated by our own movements. [More]
Study provides neural explanation for why some skills are easier to learn than others

Study provides neural explanation for why some skills are easier to learn than others

Learning is easier when it only requires nerve cells to rearrange existing patterns of activity than when the nerve cells have to generate new patterns, a study of monkeys has found. The scientists explored the brain's capacity to learn through recordings of electrical activity of brain cell networks. [More]

Unusual neural links between brainstem and injured cingulums following aneurysmal SAH

The cingulum is an important pathway for cholinergic innervation for the cerebral cortex. Many studies have reported connections between the cholinergic nuclei, especially between the cholinergic nuclei in the basal forebrain and those in the brainstem via the fornix and thalamus. [More]

Researchers show how neurons respond to sequences of familiar objects

The world grows increasingly more chaotic year after year, and our brains are constantly bombarded with images. [More]

Researchers endow mice with greater touch sensitivity by striking brain rhythm

By striking up the right rhythm in the right brain region at the right time, Brown University neuroscientists report in Nature Neuroscience that they managed to endow mice with greater touch sensitivity than other mice, making hard-to-perceive vibrations suddenly more vivid to them. [More]
Subcortical brain regions play key role in memorization process during sleep

Subcortical brain regions play key role in memorization process during sleep

According to researchers at the University of Montreal, the regions of the brain below the cortex play an important role as we train our bodies' movements and, critically, they interact more effectively after a night of sleep. [More]
People with ADHD often find difficult to make optimal decisions

People with ADHD often find difficult to make optimal decisions

Which shirt do we put on in the morning? Do we drive to work or take the train? From which takeaway joint do we want to buy lunch? We make hundreds of different decisions every day. [More]
