New way to image brain-cell activity could shed light on autism and other psychiatric disorders A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor. The researchers' new imaging technique, based on the detection of calcium ions in neurons, could help them map the brain circuits that perform such functions. It could also provide new insights into the...

Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell. The video offers a rare peek at how proteins, the brain's building blocks, are directed through neurons to renew its structure. It can be viewed online here: http://www.youtube.com/watch?v=baI9q2--q7s&feature=youtu.be "Your brain is being disassembled and reassembled every day," said Don...

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...

A new study finds that the ear delivers sound information to the brain in a surprisingly organized fashion The brain receives information from the ear in a surprisingly orderly fashion, according to a University at Buffalo study scheduled to appear June 6 in the Journal of Neuroscience. The research focuses on a section of the brain called the cochlear nucleus, the first way-station in the brain for information coming from the ear. In particular, the study examined tiny biological...

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,...

Max Planck researchers found over 2500 mRNA along dendrites and axons How do we build a memory in the brain? It is well known that for animals (and humans) new proteins are needed to establish long-term memories. During learning information is stored at the synapses, the junctions connecting nerve cells. Synapses also require new proteins in order to show changes in their strength (synaptic plasticity). Historically, scientists have focused on the cell body as the place where the required...

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish. The study provides an important proof of principle that functional motor circuits can be created outside of the body using stem cell-derived neurons and muscle cells, and that the level of communication, or...

New insight into the mechanisms that enable us to remember events precisely Scientists now have a better understanding of how precise memories are formed thanks to research led by Prof. Jean-Claude Lacaille of the University of Montreal's Department of Physiology. "In terms of human applications, these findings could help us to better understand memory impairments in neurodegenerative disorders like Alzheimer's disease," Lacaille said. The study looks at the cells in our brains, or...

UI researchers explore how one cell binds itself to another, shedding light on neurodevelopmental disorders University of Iowa biologists have advanced the knowledge of human neurodevelopmental disorders by finding that a lack of a particular group of cell adhesion molecules in the cerebral cortex–the outermost layer of the brain where language, thought and other higher functions take place –disrupts the formation of neural circuitry. Andrew Garrett, former neuroscience...

They say you can´t teach an old dog new tricks. Fortunately, this is not always true. Researchers at the Netherlands Institute for Neuroscience (NIN-KNAW) have now discovered how the adult brain can adapt to new situations. Their study may be significant in the treatment of neurodevelopmental disorders such as epilepsy, autism and schizophrenia. Ability to learn Our brain processes information in complex networks of nerve cells. The cells communicate and excite one another through...
