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...
Near-Infrared Wavelength Specificity Yields Phototherapy Insights
ARLINGTON, Texas, June 19, 2023 — Transcranial photobiomodulation (tPBM) is an emerging form of light therapy that uses LEDs or low-intensity lasers that emit near-infrared (NIR) light to stimulate the brain. Although tPBM is in the early stages of development, it shows promise as a...
High-Speed Two-Photon Microscopy Captures Rapid Bio Processes In Vivo
SUZHOU, China, May 15, 2023 — Two-photon microscopy (TPM) enables deep tissue imaging of complex biological processes at high resolution. However, the ability to visualize some biological processes, such as neural activity at the sub-millisecond scale, requires high-speed...
Novel Platform Reveals Insights into Control of Brain Network
CHAPEL HILL, N.C., Feb. 23, 2023 — Researchers at the University of North Carolina (UNC) School of Medicine combined fiber photometry with functional magnetic resonance imaging (fMRI) to examine the dynamic activity of brain regions related to the brain’s default mode network...
Photoacoustic System Enables Real-Time Neurovascular Imaging
DURHAM, N.C., May 27, 2022 — A photoacoustic imaging tool developed by Duke University researchers accommodates the need for both speed and comprehensive detail in neurovascular imaging. The imaging modality enables an approach to visualize whole-brain hemodynamics and...
Fluorescence Sensing Identifies Cancer Indicators in the Brain
MÜNSTER, Germany, May 19, 2022 — Researchers at the University Hospital Münster and Paris-Saclay University established a method to correct for artifacts caused by changes in blood flow, and recorded cell-specific lactate levels in rat brains using fluorescence signals from...
2-Level Optogenetic Device Could Broaden Options for Large-Mammal Studies
GLASGOW, Scotland, and SALT LAKE CITY, Sept. 13, 2019 — An implantable optrode array, developed by researchers at the University of Strathclyde and the University of Utah, is capable of exciting below-surface neurons in large mammal brains both by structured-light delivery and by large-volume...
The Most Wonderful Time of the Year (Video)
Jan 9, 2018 — Three conferences and two exhibitions make SPIE Photonics West the world’s largest annual event in the industry. From plenary presentations to networking opportunities, this show offers an expansive, comprehensive look at the photonics...
SPIE Gives Readers Full Access to Two Journals
BELLINGHAM, Wash., Jan. 5, 2018 — SPIE, the international society for optics and photonics, has announced that two of its journals, the Journal of Biomedical Optics and Neurophotonics, will become fully open access journals starting in January 2019. "SPIE is converting JBO and...
Photonics West Brings Together Industry’s Best, Brightest
Nov 1, 2017 — With three conferences — BiOS, LASE and OPTO — and two exhibitions, SPIE Photonics West is the world’s largest annual event for the photonics, laser and biomedical optics industries. And it’s just around the corner —...
Optical Probe Overcomes Light Scattering in Deep-Brain Imaging
PASADENA, Calif., Dec. 12, 2016 — An implantable, ultra-narrow photonic probe has been developed which is able to deliver light deep within brain tissues. Current methods, which project spatially patterned light via free-space optics, excite neurons within superficial layers of the...
SPIE Launching Neurophotonics Journal in 2014
BELLINGHAM, Wash., Oct. 31, 2013 — SPIE is launching the peer-reviewed journal Neurophotonics under Editor-in-Chief David Boas of Massachusetts General Hospital (MGH), the society said this week. The new journal will focus on novel optical technologies for imaging and manipulation of...
