A Brain Circuit to Push Past Nutritional Stress

Aug. 24, 2016 — Nutritional stress is a normal part of life; going hungry on a short-term basis generally does not impair important functions. The brain coordinates the response to nutritional stress but how it does ... read more

Aug. 22, 2016 — Scientists have demonstrated the role of lysosomal vesicles in transporting alpha-synuclein aggregates, responsible for Parkinson's and other neurodegenerative diseases, between neurons. These ... read more

Electrical Synapses in the Brain Offer New Avenue for Epilepsy Research and Possible Treatment

Aug. 19, 2016 — A child with absence epilepsy may be in the middle of doing something—she could be dancing, studying, talking—when all of a sudden she stares off into space for a few moments. Then, as quickly as ... read more

Study Supports New Strategy to Fight Cocaine Addiction

Aug. 18, 2016 — Strong evidence supporting a new strategy against drug addiction has been revealed by research. The researchers showed that a compound that inhibits the activity of certain brain-cell receptors can ... read more

Can't Stand the Heat? Study Reveals How We Figure out If We're Too Hot

Aug. 17, 2016 — With temperatures soaring, our ability to detect and avoid places that are too warm is vital for regulating our body temperature. However, until now, little was known about the molecular mechanisms ... read more

Curbing the Life-Long Effects of Traumatic Brain Injury

Aug. 17, 2016 — A fall down the stairs, a car crash, a sports injury or an explosive blast can all cause traumatic brain injury (TBI). Patients often recover. But in the days or weeks following the hit, they can ... read more

Aug. 17, 2016 — The brain has exquisitely organized communication machinery that ensures ultrafast transmission of signals between neurons. Like cargo-carrying boats, tiny bubbles packed with neurotransmitters dock ... read more

Potential Therapeutic Target for Huntington's Disease

Aug. 16, 2016 — There is new hope in the fight against Huntington's disease. Scientists have discovered that changing a specific part of the huntingtin protein prevented the loss of critical brain cells and ... read more

Microscale and Macroscale Brain Disruptions Are Associated in Schizophrenia

Aug. 16, 2016 — Brain abnormalities in schizophrenia have been identified at the microscale (alterations in synaptic connections between neurons) and the macroscale (altered connections between brain regions). ... read more

Researchers Examine How Parkinson's Disease Alters Brain Activity Over Time

Aug. 15, 2016 — Neuroscientists peered into the brains of patients with Parkinson's disease and two similar conditions to see how their neural responses changed over time. The study may provide a new tool for ... read more

Aug. 15, 2016 — Neuroscientists have identified the neural networks that connect the cerebral cortex to the adrenal medulla, which is responsible for the body's rapid response in stressful situations. These ... read more

Aug. 15, 2016 — A new, non-invasive way to track the progression of Parkinson’s disease could help evaluate experimental treatments to slow or stop the disease’s progression, say ... read more

Defect in Process That Controls Gene Expression May Contribute to Huntington's Disease

Aug. 15, 2016 — Researchers have identified a gene silencing mechanism that maintains neuronal specification and protects against neurodegeneration, a new report ... read more

Sugar Addiction: Discovery of a Brain Sugar Switch

Aug. 12, 2016 — Researchers have discovered that our brain actively takes sugar from the blood. Prior to this, researchers had assumed that this was a purely passive process. The transportation of sugar into the ... read more

Aug. 12, 2016 — Humans have evolved a disproportionately large brain as a result of sizing each other up in large cooperative social groups, researchers have ... read more

Study of Brain Activity Shows That Food Commercials Influence Children's Food Choices

Aug. 12, 2016 — Food advertising is a multi-billion dollar industry, with approximately $1.8 billion annually aimed at children and adolescents, who view 1,000-2,000 ads per year. Some studies have shown there is a ... read more

Structural Images Shed New Light on a Cancer-Linked Potassium Channel

Aug. 11, 2016 — Using cryo-electron microscopy, researchers gained new insights about how the channel functions based on what they saw in the section that spans the cell's membrane. The channel has been found ... read more

First Treatment for Spinal Muscular Atrophy to Be Submitted for FDA Approval Based on Positive Results in Clinical Trial

Aug. 11, 2016 — A major milestone was reached when nusinersen, an investigational treatment for spinal muscular atrophy (SMA), was shown to significantly improve achievement of motor milestones in babies with ... read more

Aug. 11, 2016 — Researchers have used a gene editing tool called CRISPR to turn cells isolated from mouse connective tissue directly into neuronal cells. Results indicate that the newly converted neuronal cells show ... read more

Aug. 11, 2016 — Eight people who have spent years paralyzed from spinal cord injuries have regained partial sensation and muscle control in their lower limbs after training with brain-controlled robotics, according ... read more
