Level of salts in the brain play critical role in controlling sleep-wake cycle

Danish research is behind a new epoch-making discovery, which may prove decisive to future brain research. The level of salts in the brain plays a critical role in whether we are asleep or awake. This discovery may be of great importance to research on psychiatric diseases such as schizophrenia and convulsive fits from lack of sleep as well as post-anaesthetization confusion, according to Professor Maiken Nedergaard.

Elusive brain receptor may play vital role in death of neurons from neurological diseases

Strokes, seizures, traumatic brain injury and schizophrenia: these conditions can cause persistent, widespread acidity around neurons in the brain. But exactly how that acidity affects brain function isn't well understood.

Researchers explore changes in Parkinson's-affected cells at different stages of the disease

It's an unsettling thought: You could be walking around for 20 years developing Parkinson's disease and not even know it.

Changes in the brain make people prone to alcoholism

The brain tissue of persons with alcohol dependence shows a variety of changes compared to non-alcoholic control persons. All alcoholics' brains share some characteristics, but some are exclusive to the brain tissue of anxiety-prone type 1 alcoholics or impulsive type 2 alcoholics, according to a recent study from the University of Eastern Finland.

Dopamine neuron transplants controlled by designer drug may fight Parkinson's disease in mice

A University of Wisconsin-Madison neuroscientist has inserted a genetic switch into nerve cells so a patient can alter their activity by taking designer drugs that would not affect any other cell. The cells in question are neurons and make the neurotransmitter dopamine, whose deficiency is the culprit in the widespread movement disorder Parkinson's disease.

Disrupted memory pathways uncovered in epilepsy patients

A study in rats, backed up by results in patients, has revealed how interictal epileptiform discharges may lead to memory impairments in patients with epilepsy.

Researchers identify role of darks in visual brain maps

Scientists have been studying how visual space is mapped in the cerebral cortex for many decades under the assumption that the map is equal for lights and darks. Surprisingly, recent work demonstrates that visual brain maps are dark-centric and that, just as stars rotate around black holes in the Universe, lights rotate around darks in the brain representation of visual space.

New miniaturized microscope offers unprecedented insight into nervous system function

A microscope about the size of a penny is giving scientists a new window into the everyday activity of cells within the spinal cord. The innovative technology revealed that astrocytes--cells in the nervous system that do not conduct electrical signals and were traditionally viewed as merely supportive--unexpectedly react to intense sensation.

Experimental cancer drug Nutlin-3 shows promise in cancelling effects of fragile X syndrome

A University of Wisconsin-Madison researcher who studies the most common genetic intellectual disability has used an experimental drug to reverse — in mice — damage from the mutation that causes the syndrome.

Group of gamma-protocadherins linked with neurons help regulate growth of dendrites

When you think of a neuron, imagine a tree. A healthy brain cell indeed looks like a tree with a full canopy. There's a trunk, which is the cell's nucleus; there's a root system, embodied in a single axon; and there are the branches, called dendrites.

Rapamycin drug could target neural damage linked to Leigh syndrome

Salk Institute scientists showed how an FDA-approved drug boosts the health of brain cells by limiting their energy use. Like removing unnecessary lighting from a financially strapped household to save on electricity bills, the drug--called rapamycin--prolongs the survival of diseased neurons by forcing them to reduce protein production to conserve cellular energy.

UNC-Chapel Hill researchers identify functional brain circuit that controls alcohol binge drinking

Researchers at the University of North Carolina at Chapel Hill have identified a circuit between two brain regions that controls alcohol binge drinking, offering a more complete picture on what drives a behavior that costs the United States more than $170 billion annually and how it can be treated.

Study reveals new function for CACNA1C gene in psychiatric diseases

A new study shows the death of newborn brain cells may be linked to a genetic risk factor for five major psychiatric diseases, and at the same time shows a compound currently being developed for use in humans may have therapeutic value for these diseases by preventing the cells from dying.

New fruit fly model study reveals metabolic pathway that can be targeted to treat FXS patients

Fragile X syndrome (FXS) is the most common genetically inherited cause of intellectual disability in humans. New research shows how the hormone insulin -- usually associated with diabetes -- is involved in the daily activity patterns and cognitive deficits in the fruitfly model of FXS, according to a new study from the Perelman School of Medicine at the University of Pennsylvania published online this month in Molecular Psychiatry in advance of the print issue.

Scientists unravel mystery of disrupted communication between brain cells in Parkinson's patients

A possible cause has been found for the disrupted communication between brain cells exhibited by Parkinson's patients. Bettina Schwab, a researcher at the University of Twente in The Netherlands, discovered that this group of patients have increased concentrations of a certain type of protein. Ms Schwab defended her doctoral dissertation on Friday 22 April.

University of Leicester-led study finds way to reverse symptoms of Parkinson’s and Alzheimer’s

A five-year study by an international team led from the University of Leicester has found a way of ‘reversing’ symptoms of neurodegenerative diseases such as Parkinson’s and Alzheimer’s – using fruit flies as test subjects.

Same genetic changes responsible for gastrointestinal problems in children with autism

Researchers at Columbia University Medical Center have found evidence in mice that, for some types of autism, gastrointestinal difficulties may originate from the same genetic changes that lead to the behavioral and social characteristics of the condition. The study was published in the Journal of Clinical Investigation.

Study sheds light on mechanism of empty memories in epileptic patients

Between seizures and continually, brain cells in epileptic patients send signals that make "empty memories," perhaps explaining the learning problems faced by up to 40 percent of patients. This is the finding of a study in rats and humans led by researchers at NYU Langone Medical Center and published April 25 in Nature Medicine.

Brain chemical dopamine plays key role in representing or encoding movement

Princeton University researchers have found that dopamine - a brain chemical involved in learning, motivation and many other functions - also has a direct role in representing or encoding movement. The finding could help researchers better understand dopamine's role in movement-related disorders such as Parkinson's disease.

Lab-grown mini-brains shed light on health crisis posed by Zika virus in fetal brains

Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its outer layer, the cortex.
