New research uncovers a molecular mechanism that links diabetes with an increased risk of cardiovascular problems and sudden cardiac death. The study, published by Cell Press in the June 24 issue of the journal Neuron, finds that high blood sugar prevents vital communication between the brain and the autonomic nervous system, which controls many involuntary activities in the body. "Diseases, such as diabetes, that disturb the function of the autonomic nervous system cause a wide range of...

Effective brain function depends on the efficient signaling from one neuron to the next, a lightning-fast process that depends on a quick release of neurotransmitters at synapses. Exposure to lead during early childhood and even later in life has long been known to affect the release of these critical neurotransmitters. However, the precise mechanism by which lead ions (Pb2+) impair this process has remained unknown. A new study led by Tomás Guilarte, PhD, chair of Environmental Health...

UC San Diego researchers say too much alpha-synuclein shuts down cell communications, helps cause dementia In diverse neurodegenerative diseases ranging from Parkinson's to Alzheimer's, researchers have long noted accumulations of a little-understood neuronal protein called ÃŽ±-synuclein. Pathological and genetic evidence strongly suggested that excessive ÃŽ±-synuclein played a role in the evolution of these diseases, but it was unclear how too much...

Astrocytes are the most common type of cell in the brain and play an important role in the function of neurons "“ nerve cells. New research from the University of Gothenburg, Sweden, shows that they are also directly involved in the regulation of signalling between neurons. "Our results contribute to the insight that astrocytes can affect how the brain processes and stores information," says My Andersson, a researcher from the Department of Physiology at the Institute of Neuroscience...

Cultured cells in microfluidic chambers enable systematic experiments at the synapse In order to be able to understand complex organs such as the brain or the nervous system, simplified model systems are required. A group of scientists led by the Frankfurt brain researcher Erin Schuman has successfully developed a novel method to grow cultured neurons in order to investigate basic mechanisms of memory. The researchers grew two separate populations of neurons in microfluidic platforms. These...

A cat can recognize a face faster and more efficiently than a supercomputer. That's one reason a feline brain is the model for a biologically-inspired computer project involving the University of Michigan. U-M computer engineer Wei Lu has taken a step toward developing this revolutionary type of machine that could be capable of learning and recognizing, as well as making more complex decisions and performing more tasks simultaneously than conventional computers can. Lu previously built a...

Durham, N.C. "“ Duke University Medical Center scientists crowded around a laser-powered microscope in a darkened room to peer into the brain of an anesthetized juvenile songbird right after he heard an adult tutors' song for the first time. Specifically, they wanted to see what happened to the connections between nerve cells, or synapses, in a part of the brain where the motor commands for song are thought to originate. In the first experiment of its kind, they employed high...

A new study from The Montreal Neurological Institute and Hospital "“ The Neuro - at McGill University is the first to discover a molecular link between Parkinson's disease and defects in the ability of nerve cells to communicate. The study, published in the prestigious journal Molecular Cell and selected as Editor's Choice in the prominent journal Science, provides new insight into the mechanisms underlying Parkinson's disease, and could lead to innovative new therapeutic strategies....

A fundamental function of neurons "“ key brain cells "“ is the release of hormones and chemicals called neurotransmitters that contain chemical messages. Until recently, experts were perplexed about the role of small proteins called complexins. Did they help or hinder the release of these important proteins? In a recent report, Baylor College of Medicine researchers answered the question. They do both, depending on the species in which they are active. A balance "The balance...
