Transmission of nerve signals is enhanced in the insects that eat less A novel technique for measuring tiny, rapid-fire secretions in the brains and mouthparts of fruit flies (drosophila) is providing insights into the beneficial effects of eating less – information that ultimately could help people suffering from neuromuscular disorders. Using the method, researchers uncovered never-before-seen brain chemistry that helps explain why fruit flies genetically manipulated to mimic...

Research findings may lead to new drugs designed to improve communication between brain cells and effectively treat neurological disorders Scientists at Weill Cornell Medical College have discovered that the single protein -- alpha 2 delta -- exerts a spigot-like function, controlling the volume of neurotransmitters and other chemicals that flow between the synapses of brain neurons. The study, published online in Nature, shows how brain cells talk to each other through these signals,...

A fundamental new discovery about how nerve cells in the brain store and release tiny sacs filled with chemicals may radically alter the way scientists think about neurotransmission — the electrical signaling in the brain that enables everything from the way we move, to how we remember and sense the world. According to the scientists at the University of California, San Francisco (UCSF) who conducted the research, the discovery doesn´t change the players involved so much as it...

New studies illuminate brain's complex neurotransmission machinery, point to potential source of problems leading to neurodegenerative and psychiatric conditions Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons -- a dance of chemical messages so delicate that missteps often lead to neurological dysfunction. A recent Nature Neuroscience study led by Dr....

How GABA transmission regulates synaptic adhesion at developing inhibitory synapses Newly published research led by Professor Z. Josh Huang, Ph.D., of Cold Spring Harbor Laboratory (CSHL) sheds important new light on how neurons in the developing brain make connections with one another. This activity, called synapse validation, is at the heart of the process by which neural circuits self-assemble, and is directly implicated in pathology that gives rise to devastating neurodevelopmental...

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...

Drosophila larvae avoid light during the foraging stage of their development. Research published in the open access journal BMC Neuroscience shows that both 5-HT (serotonergic) and corazonergic neurons have a role in regulating this behavior.To identify which neurons modulate the larvae's photobehavior, Ver³nica G. Rodriguez Moncalvo and Ana Regina Campos from McMaster University, Ontario, Canada analysed Drosophila larvae which had been genetically engineered to achieve suppressed...

Researchers have constructed a new detailed map of the three-dimensional terrain of a synapse -- the junction between neurons which are critical for communication in the brain and nervous system. The "nano-map," which shows the tiny spines and valleys resolved at nanometer scale, or one-billionth of a meter, has already proven its worth in changing scientists' views of the synaptic landscape. Using the map as a guide, the research team, led by Howard Hughes Medical Institute investigator...

La Jolla, CA - Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In this week's journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other. The new study indicates that...

Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message? Research reported in the July 20 issue of the Journal of Neuroscience (released online July 13) by a team led by David Featherstone, a University of Illinois at Chicago assistant professor of biology, provides...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
