Graphene electrodes could enable higher quality brain imaging thanks to new research by a team of engineers and neuroscientists at the University of California, San Diego. The researchers developed a technique, using platinum nanoparticles, to lower the impedance of graphene electrodes by 100 times, while keeping them transparent. In tests on transgenic mice, the electrodes were able to record and image neuronal activity (calcium ion spikes) of large groups of neurons and brain cells.Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2021 budget of $8.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
