LED light instantly triggers or reverses depression-like behavior in rodents

A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced pleasure-seeking - they avoided other animals and lost their sweet tooth.

Physical activity improves brain function in older generations

The physical benefits of regular exercise and remaining physically active, especially as we age, are well documented. However, it appears that it is not only the body which benefits from exercise, but the mind too. The evidence for this is published in a new review by Hayley Guiney and Liana Machado from the University of Otago, New Zealand, which focuses on the importance of physical activity in keeping and potentially improving cognitive function throughout life.

TU Darmstadt’s biosensor can diagnose African sleeping sickness before it breaks out

African sleeping sickness is an infectious disease that is widespread south of the Sahara Desert. Although the around sixty million people residing in tropical Africa run the risk of becoming infected with the disease every day, only around four million of them are monitored for the disease by disease-control authorities.

New ESF strategic report identifies opportunities for research on human brain

A new strategic report, The Human Brain - From Cells to Society, Toward Better Mental Health in Europe, has been published today by the European Science Foundation (ESF). In a Europe where an estimated 38% of the population is affected by a disorder of the brain, it is becoming increasingly important to bring greater support to research in all areas of neuroscience.

Opioids already in the body can enhance malignant tendencies of human cancer cells

A study led by University of Chicago researcher Patrick A. Singleton, Ph.D. and published in the journal Anesthesiology has shown that, even without the addition of further opioids such as morphine, opioids already in the body can enhance the malignant tendencies of human cancer cells.

Change of fatty diet can cause feelings like drug withdrawal and depression

Even before obesity occurs, eating fatty and sugary foods causes chemical changes in the brain, meaning that going on a diet might feel similar to going through drug withdrawal, according to a study published today by Dr. Stephanie Fulton of the University of Montreal's Faculty of Medicine and its affiliated CRCHUM Hospital Research Centre.

Targeted micro-bubbles could help detect heart disease

Heart disease is a leading cause of death throughout the world. Doctors say that it is important to detect heart disease early before it becomes too serious. Now, researchers at the University of Missouri have found a way that they believe could help detect heart disease before it progresses too far as well as identify patients who are at risk for strokes.

GM604 target regulates over 4,000 genes: Genervon

Genervon scientists have confirmed that the target of GM604 regulates over 4,000 genes. More significantly, it modifies ALS disease progression by modulating at least 30 significant ALS related genes. It does this through at least 8 pathways, potentially more, and up to 22 biological processes.

Novel tactile conditioning experiment using honey bees

Honey bees are a highly organized, social species, as demonstrated by their complex colonies and the geometric structure of their hives. For hive building, the honey bee strongly relies on its tactile sense, and a new video-article in JoVE (Journal of Visualized Experiments) illustrates a novel tactile conditioning experiment using honey bees.

AZD6765 briefly improves treatment-resistant patients' depression symptoms in minutes

A drug that works through the same brain mechanism as the fast-acting antidepressant ketamine briefly improved treatment-resistant patients' depression symptoms in minutes, with minimal untoward side effects, in a clinical trial conducted by the National Institutes of Health. The experimental agent, called AZD6765, acts through the brain's glutamate chemical messenger system.

Skin vibrations convey information to the brain much the same way as auditory system

When you walk into a darkened room, your first instinct is to feel around for a light switch. You slide your hand along the wall, feeling the transition from the doorframe to the painted drywall, and then up and down until you find the metal or plastic plate of the switch. During the process you use your sense of touch to develop an image in your mind of the wall's surface and make a better guess for where the switch is.
