Researchers Develop High-Precision Dual-Color Optogenetic Brain Probe
AMHERST, Mass., Dec. 26, 2023 — Optogenetics promises to manipulate brain circuitry by exciting or inhibiting neurons with different wavelengths of light. Until now, neural probes have largely been limited to single colors, only capable of either excitation or inhibition. Probes with close-packed dual-color light sources have proven elusive due to difficulties in integrating the necessary technology. Now, researchers at the University of Massachusetts Amherst have developed a dual color optogenetic neural
Neuroscience 2023 Places Spotlight on Discovery, Industry Collaboration

International Consortium to Develop Photonic Tools for Deep Brain Imaging
GENOA, Italy, Feb. 1, 2021 — In the amount of €5.7 million (approximately $7 million), the European Union is funding a 12-partner, eight-country project aimed at developing photonic technologies to access and image deep regions of the brain. Funded for the next four years,...
ZEISS, MPFI to Collaborate on Brain Imaging
WHITE PLAINS, NY, Jan. 12, 2021 — A collaboration between ZEISS and Max Planck Florida Institute (MPFI) for Neuroscience aims to increase resolution and signal-to-noise in the process of imaging regions of the brain that are unreachable with traditional in vivo microscopy. Per the...
Vision for Primate Neuroimaging to Accelerate Scientific and Medical Breakthroughs
NEW YORK, Feb. 20, 2020 — A global community of over 150 scientists studying the primate brain has released a blueprint for developing more complete “wiring diagrams” of how the brain works that may ultimately improve understanding of several brain disorders....
Tapered Optical Fiber Performs Multisite Photometry in the Brain
LECCE, Italy, Nov. 26, 2019 — Researchers from Istituto Italiano di Tecnologia (IIT), the University of Salento, and Harvard Medical School have developed a light-based method to capture and pinpoint neural activity in the brain. The new method allows signals from various brain...
LOTUS-V Brain Imaging Technique Shows Promise In Neuroscience
OSAKA, Japan, June 7, 2019 — Researchers at Osaka University have developed a method to record brain activity in multiple freely moving mice simultaneously. The method is based on a recent bioluminescence-based indicator of membrane voltage. Researchers applied the indicator...
Ultrafast Optics Faces Challenges Outside of Research Labs
Jul 10, 2017 — Ultrafast optics is currently a scientifically dominated area with a lot of dynamics in both research and development. Often, complex setups make it challenging to create compact devices that can be employed for applications outside of the...
