Tübinger Neurowissenschaftler untersuchen, wie Bewegungen gesteuert werden

Obwohl wir uns dessen nur selten bewusst sind, beruhen schon einfachste Bewegungen unseres Körpers wie das Heben einer Hand auf der komplexen Kommunikation zahlreicher verteilter Hirnregionen. Neuere Befunde legen nahe, dass die rhythmische elektrische Aktivität von Nervenzellen wesentlich für diese Kommunikationsprozesse ist. Jedoch ist die genaue Funktion verschiedener Hirnrhythmen und ihrer Wechselwirkungen bislang weitestgehend unbekannt. (more…)

Initial results in mice could lead to new way to fight neurodegenerative diseases

There’s new hope in the fight against Huntington’s disease. A group of researchers that includes scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice.

The compound is a synthetic antioxidant that targets mitochondria, an organelle within cells that serves as a cell’s power plant. Oxidative damage to mitochondria is implicated in many neurodegenerative diseases including Alzheimer’s, Parkinson’s, and Huntington’s. (more…)

More Sophisticated Wiring, Not Just a Bigger Brain, Helped Humans Evolve Beyond Chimps

Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin?

A new UCLA study pinpoints uniquely human patterns of gene activity in the brain that could shed light on how we evolved differently than our closest relative. The identification of these genes could improve understanding of human brain diseases like autism and schizophrenia, as well as learning disorders and addictions.

The research appears Aug. 22 in the advance online edition of the journal Neuron. (more…)

To Ditch Dessert, Feed the Brain

If the brain goes hungry, Twinkies look a lot better, a study led by researchers at Yale University and the University of Southern California has found.

Brain imaging scans show that when glucose levels drop, an area of the brain known to regulate emotions and impulses loses the ability to dampen desire for high-calorie food, according to the study published online September 19 in The Journal of Clinical Investigation. (more…)
