Therapeutic small molecules safely prevent blood clots without excessive bleeding

It may be possible to disrupt harmful blood clots in people at risk for heart attack or stroke without increasing their risk of bleeding, according to a new study published in Nature Communications.

Brain changes after stroke may lead to increased preference for alcohol, research suggests

Brain changes after stroke may lead to increase in alcohol-seeking behavior, at least in animal models, according to research published Wednesday in the journal Scientific Reports.

New research recasts timeline for development of the brain's vision-processing center

The visual cortex, the human brain's vision-processing center that was previously thought to mature and stabilize in the first few years of life, actually continues to develop until sometime in the late 30s or early 40s, a McMaster neuroscientist and her colleagues have found.

Visual cortex of the brain develops gradually throughout life, study reveals

A study of post-mortem brain tissue reveals the human primary visual cortex (V1) develops gradually throughout life.

Rat study shows impact of early exposure to high-fat diet on the dopamine system in adulthood

Exposure to high-fat diet from childhood may increase the sensitivity of the dopamine system later in adulthood, according to a study in male rats published in eNeuro. The research describes potential mechanisms that, if translated to humans, may drive people to seek foods that contribute to obesity.

Troubles with normal dreaming may be early warning sign for neurological conditions

Dr. John Peever at the University of Toronto has been working to answer one of humanity's greatest questions: how do we dream? He has found a certain area of the brain is responsible for this phenomenon and that troubles with normal dreaming may be an early warning sign for ailments such as Parkinson's Disease.

Visual brain also involved in prediction of future events, say neuroscientists

For a long time, researchers thought of the visual cortex as a brain area that determines what you perceive based on information coming from the eyes. Neuroscientists from Radboud University now show that the area is also involved in the prediction of future events. Nature Communications publishes the results on May 23.

Study offers new insights into brain mechanisms for spatial navigation

An international research team led by UvA researchers Jeroen Bos, Martin Vinck and Cyriel Pennartz has identified a new type of neuron which might play a vital role in humans' ability to navigate their environments. The discovery is an important step towards understanding how the brain codes navigation behaviour at larger scales and could potentially open up new treatment strategies for people with impaired topographical orientation like Alzheimer's patients.

New device can help stroke patients recover some control over paralyzed limbs

Stroke patients who learned to use their minds to open and close a device fitted over their paralyzed hands gained some control over their hands, according to a new study from Washington University School of Medicine in St. Louis.

Chronic sleep deprivation increases risk of neurological disorders

Recent research in mice indicates that destructive activity of cells in the brain is increased after sleep deprivation and may increase the risk of developing dementia, such as Alzheimer's disease.

Gray matter density increases during transition from childhood to young adulthood, study reveals

For years, the common narrative in human developmental neuroimaging has been that gray matter in the brain - the tissue found in regions of the brain responsible for muscle control, sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control -- declines in adolescence, a finding derived mainly from studies of gray matter volume and cortical thickness (the thickness of the outer layers of brain that contain gray matter).

Scientists report brain network organization changes that underlie improvements in executive function

As children age into adolescence and on into young adulthood, they show dramatic improvements in their ability to control impulses, stay organized, and make decisions.

Study provides greater understanding of psychology behind fear

What happens in the brain when we see other people experiencing a trauma or being subjected to pain? Well, the same regions that are involved when we feel pain ourselves are also activated when we observe other people who appear to be going through some painful experience.

Toddler's gender influences the brain responses and behavior of fathers

A toddler's gender influences the brain responses as well as the behavior of fathers -- from how attentive they are to their child, to the types of language that they use and the play that they engage in, a new study by Emory University finds.

Study finds variations among hospitals in transitioning stroke patients from treatment to comfort care

Hospitals vary widely in how often they transition people with strokes from active treatment to comfort or hospice care within 48 hours after they get to the hospital, according to a new study published in the May 24, 2017, online issue of Neurology Clinical Practice, an official journal of the American Academy of Neurology.

New findings provide insights into brain mechanisms underlying alcohol addiction

The human brain functions on a delicate balance of reinforcing positive behaviors and suppressing negative ones, which takes place in the dorsal striatum, a brain region critical for goal-directed behavior and implicated in drug and alcohol addiction.

Researchers develop new tool to map the brain during surgery

Researchers have developed a new device to map the brain during surgery and distinguish between healthy and diseased tissues. The device provides higher resolution neural readings than existing tools used in the clinic and could enable doctors to perform safer, more precise brain surgeries.

UCLA study characterizes brain differences between people with genetic risk for schizophrenia, autism

A UCLA study characterizes, for the first time, brain differences between people with a specific genetic risk for schizophrenia and those at risk for autism, and the findings could help explain the biological underpinnings of these neuropsychiatric disorders.

The brain discovers and avoids disease much better than previously thought

The human brain is much better than previously thought at discovering and avoiding disease, a new study led by researchers at Karolinska Institutet in Sweden reports.
