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...

When a locust jumps and flies away from potential danger, the insect is reacting through a complex mathematical computation of sensory inputs completed within the nervous system. Researchers at Baylor College of Medicine have pinpointed how and when that computation is completed, resulting in a safe get-away. In the current edition of The Journal of Neuroscience, the researchers show that it happens within a single neuron. The locust uses two variables to determine when to jump -- speed...

Researchers at the EPFL have discovered rules that relate the genes that a neuron switches on and off, to the shape of that neuron, its electrical properties and its location in the brain The discovery, using state-of-the-art informatics tools, increases the likelihood that it will be possible to predict much of the fundamental structure and function of the brain without having to measure every aspect of it. That in turn makes the Holy Grail of modelling the brain in silico–the goal...

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...

A new study reveals a dazzling degree of biological diversity in an unexpected place — a single neural connection in the body wall of flies. The finding, reported in this week's online edition of the Proceedings of the National Academy of Sciences, raises several interesting questions about the importance of structure in the nervous system and the evolution of neural wiring. "We know almost nothing about the evolution of the nervous system, although we know it has to happen...

There are a number of drugs and experimental conditions that can block cognitive function and impair learning and memory. However, scientists have recently shown that some drugs can actually improve cognitive function, which may have implications for our understanding of cognitive disorders such as Alzheimer's disease. The new research is reported 21 February in the open-access journal PLoS Biology. The study, led by Drs. Jose A. Esteban, Shira Knafo and Cesar Venero, is the result of...

Researchers reveal a novel mechanism through which the brain may become more reluctant to function as we grow older New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older. It is not fully understood why the brain's cognitive functions such as memory and speech decline as we age. Although work published this year...
