New research by scientists at the University of North Carolina School of Medicine may have pinpointed an underlying cause of the seizures that affect 90 percent of people with Angelman syndrome (AS), a neurodevelopmental disorder. Published online Thursday June 7, 2012 in the journal Neuron, researchers led by Benjamin D. Philpot, PhD, professor of cell and molecular physiology at UNC, describe how seizures in individuals with AS could be linked to an imbalance in the activity of specific...

Use of transplanted induced pluripotent stem cells could lead to new treatments for HD Researchers from South Korea, Sweden, and the United States have collaborated on a project to restore neuron function to parts of the brain damaged by Huntington´s disease (HD) by successfully transplanting HD-induced pluripotent stem cells into animal models. Induced pluripotent stem cells (iPSCs) can be genetically engineered from human somatic cells such as skin, and can be used to model...

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...

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...

No matter what novel objects we come to behold, our brains effortlessly take us from an initial "What's that?" to "Oh, that old thing" after a few casual encounters. In research that helps shed light on the malleability of this recognition process, Brown University neuroscientists have teased apart the potentially different roles that two distinct cell types may play. In a study published in the journal Neuron, the researchers document that this kind of learning is based in the inferior...

Researchers identify the novel expression of an ion channel in neurons of the brain Research at the University of Calgary's Hotchkiss Brain Institute (HBI) has demonstrated the novel expression of an ion channel in Purkinje cells — specialized neurons in the cerebellum, the area of the brain responsible for movement. Ray W. Turner, PhD, Professor in the Department of Cell Biology & Anatomy and PhD student Jordan Engbers and colleagues published this finding in the January edition...

Quite early in its development, the mammalian brain has all the raw materials on hand to forge complex neural networks. But forming the connections that make these intricate networks so exquisitely functional is a process that occurs one synapse at a time. An important question for neuroscience has been: how exactly do stable synapses form? How do nerve cells of particular types know which of their cortical neighbors to "synapse" with, and which to leave out of their emerging networks?...

RUB scientists decipher the role of calcium signals Bochum's neurobiologists have found that certain receptors for the neurotransmitter glutamate determine the architecture of nerve cells in the developing brain. Individual receptor variants lead to especially long and branched processes called dendrites, which the cells communicate with. The researchers also showed that the growth-promoting property of the receptors is linked to how much calcium they allow to flow into the cells....

20 mouse lines provide views of cortical GABA neurons not previously possible A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has succeeded in creating what amounts to a GPS system for locating and tracking a vital class of brain cells that until now has eluded comprehensive identification, particularly in living animals. The cells in question are the class of neurons that release the neurotransmitter called GABA (gamma aminobutyric acid). GABA neurons function to...
