New Study to Test Unusual Hypothesis on Beta Brainwaves

Beta oscillations are tightly linked to Parkinson’s disease and the ability to process sensory information, such as touch. Two neuroscientists have brought their collaboration to Brown University and won funding from the National Science Foundation to see if they can finally provide a definitive, if unorthodox, explanation for beta brainwaves.

Before she could seek to convince the world that her computer model of a key brain circuit explains a fundamental, 80-year-old mystery of neuroscience with potential relevance to Parkinson’s disease, Stephanie Jones sought to convince Christopher Moore. The new Brown neuroscience professors are now close collaborators, but when they first started talking about the beta oscillations of the cortex, Moore thought Jones was plain wrong, if not a bit nuts.

Critical genetic secrets of a bacterium that holds potential for removing toxic and radioactive waste from the environment have been revealed in a study by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). The researchers have provided the first ever map of the genes that determine how these bacteria interact with their surrounding environment.

“Knowing how bacteria respond to environmental changes is crucial to our understanding of how their physiology tracks with consequences that are both good, such as bioremediation, and bad, such as biofouling,” says Aindrila Mukhopadhyay, a chemist with Berkeley Lab’s Physical Biosciences Division, who led this research. “We have reported the first systematic mapping of the genes in a sulfate-reducing bacterium – Desulfovibrio vulgaris – that regulate the mechanisms by which the bacteria perceive and respond to environmental signals.” (more…)
