Comparative silence between firing spikes of neurons reveals what they are really up to

It's the comparative silence between the firing spikes of neurons that tells what they are really up to, scientists report.

Fat and carb rich foods preferred by the brain

We might all be aware of the harmful effects of junk food on health. This does not stop our brains from craving fat-rich and sugar loaded foods finds a new study. The study titled, “Supra-Additive Effects of Combining Fat and Carbohydrate on Food Reward,” was published today in the latest issue of the journal Cell Metabolism.

MSU scientists discover early cause of intestinal inflammation

Michigan State University scientists have identified an early cause of intestinal inflammation, one of the first stages of inflammatory bowel disease and irritable bowel syndrome, which afflict around 11 percent of the world's population.

Scientists locate neurons involved in fear reduction in long-term trauma

As reported in the journal Science, the researchers found that a reduction in long-lasting trauma (remote fear) is connected to the activity of the same group of neurons that are involved in storing the memories in the first place.

Research sheds light on pathways involved in transmitting itch sensations from skin to brain

Researchers from North Carolina State University have pinpointed a particular neuropeptide associated with transmitting itch signals in mice with atopic dermatitis.

New studies on fat cell filling, history of biochemistry, and ketogenic diet

There's more than one type of fat cell. Besides the white fat that stores triglycerides in lipid droplets in preparation for lean times later, mammals also have heat-generating brown fat, which acts more like a radiator than a storage closet.

Scientists discover unique feature in the 'antennae' of light-sensing neurons

Scientists at Baylor College of Medicine and Radboud University Medical Center in the Netherlands have discovered that the antennae-like structures on light-sensing neurons, called photoreceptors, have a unique feature not observed in the 'antennae' or cilia of other types of cells.

Scientists develop method to determine metabolic activity of neural networks

During the last decade, neurobiologists's attention has been focused on the study of the functioning of neural networks rather than single nerve cells.

New study takes researchers one step closer to understanding consciousness

Consciousness is everything people experience -- from the taste of chocolate to the pain of a migraine, the disappointment of failing an exam to the thrill of holding a newborn baby.

Waste-disposal system of cell appears to play key role in spread of Alzheimer's disease

The waste-disposal system in a cell can spread harmful protein aggregates between neurons in the brain in Alzheimer's disease, according to researchers at Linköping University, Sweden.

Researchers observe increase in activity of neurons grown on single layer of graphene

A work led by SISSA and published on Nature Nanotechnology reports for the first time experimentally the phenomenon of ion 'trapping' by graphene carpets and its effect on the communication between neurons.

Study uncovers new molecular mechanisms of Parkinson's disease

Detailed brain cell analysis has helped researchers uncover new mechanisms thought to underlie Parkinson's disease.

Study shows how amyloid aggregates alter brain cells in Alzheimer’s disease

A new study has revealed the mechanism through which amyloid peptide aggregates alter brain cells to cause the harmful effects seen in Alzheimer’s disease.

Neuroscientists identify one single control center for sleep-wake cycle in the brain

Until now, it was thought that multiple brain areas were needed to control sleep and wakefulness. Neuroscientists from Bern have now identified one single control center for the sleep-wake cycle in the brain. The findings are of great importance for finding new sleep therapies.

Genetic mutation shown to cause bipolar disorder

Researchers have discovered a mutation that may increase the risk of bipolar disorder through a complex interplay between serotonin and mitochondrial signaling.

ANT1 mutations connect bipolar disorder with mitochondrial dysfunction

Mutations in the gene ANT1 may confer a risk for bipolar disorder through a complex interplay between serotonin and mitochondrial signaling in the brain.

Scientists examine how depressive episode affects the memory with computational model

During a depressive episode the ability of the brain to form new brain cells is reduced. Scientists of the Ruhr-Universität Bochum examined how this affects the memory with a computational model.

Researchers reverse tau-induced memory deficits in animal models

Reversing memory deficits and impairments in spatial learning is a major goal in the field of dementia research. A lack of knowledge about cellular pathways critical to the development of dementia, however, has stood in the way of significant clinical advance.

Researchers demonstrate synaptic plasticity in new-born neurons

Even in adult brains, new neurons are generated throughout a lifetime. In a publication in the scientific journal PNAS, a research group led by Goethe University describes plastic changes of adult-born neurons in the hippocampus, a critical region for learning: frequent nerve signals enlarge the spines on neuronal dendrites, which in turn enables contact with the existing neural network.

Scientists find role of schizophrenia gene in brain development

A USC research team identified 150 proteins affecting cell activity and brain development that contribute to mental disorders, including schizophrenia, bipolar condition and depression.
