Neuroscience has a very long history, one that by some measures stretches back to thousands of years B.C. Certainly, the need to understand how our brains work, why things sometimes go wrong and, ultimately, how we can fix what is broken makes it a compelling subject. Some 32,000 neuroscientists are expected to gather this month in New Orleans for the 42nd annual meeting of the Society for Neuroscience. Attendees will have the opportunity to consider the latest research into how the brain weighs complex decisions; the progress being made in treating Alzheimer’s disease, spinal cord...Read full article

    optogenetics
    A discipline that combines optics and genetics to enable the use of light to stimulate and control cells in living tissue, typically neurons, which have been genetically modified to respond to light. Only the cells that have been modified to include light-sensitive proteins will be under control of the light. The ability to selectively target cells gives researchers precise control. Using light to control the excitation, inhibition and signaling pathways of specific cells or groups of...
    quantitative phase imaging
    Quantitative phase imaging (QPI) is an advanced imaging technique used in microscopy to measure and analyze the optical phase information of transparent specimens. Unlike traditional brightfield microscopy, which relies on the absorption of light, QPI directly captures and quantifies the phase changes induced by a specimen as light passes through it. This enables the visualization of transparent structures and provides valuable quantitative information about biological and non-biological...
