Thanks to a new study of the retina, scientists at UC Santa Barbara have developed a greater understanding of how the nervous system becomes wired during early development. The findings reflect the expansion of developmental neurobiology and vision research at UCSB. The work is described in a recent publication of the Journal of Neuroscience. The research team examined the connectivity of nerve cells, called neurons, in mice. Neurons communicate with one another via synapses where the...

Harvard researcher creates neurons that light up as they fire In a scientific first that potentially could shed new light on how signals travel in the brain, how learning alters neural pathways, and might lead to speedier drug development, scientists at Harvard have created genetically-altered neurons that light up as they fire. The work, led by John L. Loeb Associate Professor of the Natural Sciences Adam Cohen, and described in Nature Methods on Nov. 28, involved using a gene from a...

Can the nerve signaling inhibitor tomosyn help retain long-term memory? A new study by two University of Illinois at Chicago biologists points to the link. Findings by Janet Richmond and David Featherstone, both professors of biological sciences at UIC, are reported in the Oct. 31 online early edition of the Proceedings of the National Academy of Sciences. "This is the first really comprehensive effort to look at the role of tomosyn in fly learning," said Richmond, who until now studied...

Research gives insight into 50-year-old mystery -- zinc important for learning and memory Zinc plays a critical role in regulating how neurons communicate with one another, and could affect how memories form and how we learn. The new research, in the current issue of Neuron, was authored by Xiao-an Zhang, now a chemistry professor at the University of Toronto Scarborough (UTSC), and colleagues at MIT and Duke University. Researchers have been trying to pin down the role of zinc in the...

Brain Makes Memories Rhythmically
2011-10-04 04:55:18

The brain learns through changes in the strength of its synapses -- the connections between neurons -- in response to stimuli. Now, in a discovery that challenges conventional wisdom on the brain mechanisms of learning, UCLA neuro-physicists have found there is an optimal brain "rhythm," or frequency, for changing synaptic strength. And further, like stations on a radio dial, each synapse is tuned to a different optimal frequency for learning. The findings, which provide a grand-unified...

The mechanism which adjusts how to receive a signal in coordination with dendritic morphology has been revealed Neurons in the brain play a role as an electric wire conveying an electrical signal. Because this electric wire is connected with various joints (synapse), various brain functions can occur. A neuron which has dendritic trees on it, receives the signals with many synapses located on those dendritic trees, and carries out functions by combining the received signals. The research...

Excitation and inhibition remain balanced, even when the brain undergoes reorganization Every second, the brain's nerve cells exchange many billions of synaptic impulses. Two kinds of synapses ensure that this flow of data is regulated: Excitatory synapses relay information from one cell to the next, while inhibitory synapses restrict the flow of information. Scientists at the Max Planck Institute of Neurobiology in Martinsried could now show, in cooperation with colleagues from the Ruhr...

By altering the genetic makeup of normally "unexcitable" cells, Duke University bioengineers have turned them into cells capable of generating and passing electrical current. This proof-of-concept advance could have broad implications in treating diseases of the nervous system or the heart, since these tissues rely on cells with the ability to communicate with adjacent cells in order to function properly. This communication is achieved through the passage of electrical impulses, known as...
