Novel mechanism for long-term learning identified by Carnegie Mellon researchers
01-03-2008 · EurekAlert!Practice makes perfect -- or at least that's what we’re told as we struggle through of multiplication tables and piano scales -- and it seems to be true. That's why neuroscientists have been perplexed by data showing that at the level of individual synapses increased, repetitive stimulation reverses gains in synaptic strength. Neuroscientists from Carnegie Mellon and the Max Planck Institute have discovered the mechanism that resolves this paradox. The findings are published in Science.

- Neuronal circuits able to rewire on the fly to sharpen senses
12-16-2007 · EurekAlert!
Researchers from the Center for the Neural Basis of Cognition, a joint project of Carnegie Mellon University and the University of Pittsburgh, have for the first time described a mechanism called "dynamic connectivity," in which neuronal circuits are rewired "on the fly" allowing stimuli to be more keenly sensed. The process is described in a paper in the January 2008 issue of Nature Neuroscience, and now available online.

- Potential New Target For Leukemia Treatment
10-10-2006 · ScienceDaily
Cincinnati Children's Hospital Medical Center researchers have identified the crucial role and novel mechanism of action of the protein RhoH GTPase in the development and activation of cells critical to the immune system. The findings suggest that RhoH GTPase may provide a target for therapeutic intervention in some types of leukemia. The paper is due to appear in an upcoming edition of the journal, Nature Immunology.

- Carnegie Mellon University scientists identify genes activated during learning and memory
04-18-2007 · EurekAlert!
Researchers have long recognized that for learning and memory to take place, certain genes must be activated to alter neuron activity inside the brain. But identifying and cataloging all the genes involved in learning is a daunting task. In the March 13 issue of BMC Neuroscience, Carnegie Mellon University scientists show how an innovative computational approach can provide a rapid way to identify the likely members of this long sought-after set of genes.

- Carnegie Mellon scientists investigate initial molecular mechanism that triggers neuronal firing
08-22-2007 · EurekAlert!
Carnegie Mellon University chemists have solved a decade-long molecular mystery that could eventually help scientists develop drug therapies to treat a variety of disorders, including epilepsy and Alzheimer's disease. Using intensive theoretical and computational calculations, Carnegie Mellon researchers have modeled the initial molecular changes that occur when the neurotransmitter glutamate docks with a receptor on a neuron, which sets in motion a chain of events that culminates in the neuron firing an electrical impulse.

- Identified mechanism in the malaria parasite to help it adapt to infected individuals
08-02-2007 · EurekAlert!
Plasmodium falciparum is responsible for the most severe forms of human malaria. Invasion of red blood cells is an essential step of the complex life cycle of this parasite. Alfred Cortés, IRB Barcelona researcher, together with researchers from NIMR, have discovered that the parasite has the ability to switch on and off the expression of some of the proteins it uses to enter its victim's red blood cells.

- Researchers find gene linked to Crohn's disease
10-26-2006 · EurekAlert!
An international team of researchers has identified another gene mutation linked to the inflammatory bowel diseases (IBD) Crohn's disease and ulcerative colitis. The team, including Johns Hopkins gastroenterologists and geneticists, says the novel mutation is in the interleukin-23 (IL-23) gene receptor present in healthy people without Crohn's disease but rare in those with the disease.
