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.

- 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.

- Carnegie Mellon University research shows how sensory-deprived brain compensates
04-17-2007 · EurekAlert!
Whiskers provide a mouse with essential information. These stiff hairs relay sensory input to the brain, which shapes neuronal activity. In a first, studies of this system by Carnegie Mellon scientists show just how well a mouse brain can compensate when limited to sensing the world through one whisker. Published April 4 in the Journal of Neuroscience, the results should help shape future studies of sensory deprivation that results from stroke or traumatic brain injury.

- 'Insulator' helps silence genes in dormant herpes virus
05-02-2007 · EurekAlert!
By adulthood, most people have suffered at least one bout of painful cold sores brought on by Herpes simplex virus 1. After the initial infection, the virus usually remains in the body, hiding out in nearby nerve cells where the victim's immune defenses cannot reach it, activating periodically to cause symptoms. Now, scientists have discovered a molecular mechanism that allows the virus to escape detection by the body's immune system for months or even years.

- Carnegie Mellon scientists develop fluorescent proteins for live cell imaging, biosensor design
02-06-2008 · EurekAlert!
Scientists at Carnegie Mellon University's Molecular Biosensor and Imaging Center have developed new "fluorogen activating proteins" that will become a key component of novel molecular biosensor technology being created at Carnegie Mellon. The FAPs, which can be used to monitor biological activities of individual proteins and other biomolecules within living cells in real time, are described in the February issue of Nature Biotechnology.

- Cocaine high caused by interference in neuronal receiving stations
12-06-2006 · EurekAlert!
Researchers have found evidence for a fundamental molecular mechanism underlying the hyperactive high of cocaine. In studies with rats, they have traced the effect to interactions between two types of receiving stations in neurons for nerve signals from their neighbors. The researchers' studies in rats found that when the animals received cocaine, a component of a receptor for the neurotransmitter dopamine tends to grab onto a component of a receptor for glutamate. The result, they found, was interference with normal activation of this glutamate receptor.
