Reports from University of Queensland Provide New Insights into Neuroimaging (MRI signal phase oscillates with neuronal activity in cerebral cortex: Implications for neuronal current imaging)

By a News Reporter-Staff News Editor at Pain & Central Nervous System Week -- Data detailed on Neurology have been presented. According to news reporting out of Brisbane, Australia, by NewsRx editors, research stated, "Neuronal activity produces transient ionic currents that may be detectable using magnetic resonance imaging (MRI). We examined the feasibility of MRI-based detection of neuronal currents using computer simulations based on the laminar cortex model (LCM)."

Our news journalists obtained a quote from the research from the University of Queensland, "Instead of simulating the activity of single neurons, we decomposed neuronal activity to action potentials (AP) and postsynaptic potentials (PSP). The geometries of dendrites and axons were generated dynamically to account for diverse neuronal morphologies. Magnetic fields associated with APs and PSPs were calculated during spontaneous and stimulated cortical activity, from which the neuronal current induced MRI signal was determined. We found that the MRI signal magnitude change (

According to the news editors, the research concluded: "These findings inform the design of MRI experiments to detect neuronal currents."
