Diamond Defects Boost Magnetic Field Sensing for Brain Activity Mapping
MELBOURNE, Australia, July 12, 2022 — A team from Fraunhofer Institute for Applied Solid State Physics (Fraunhofer IAF), with diamond sensing technology experts from RMIT University, demonstrated that magnetic-field-dependent emission from nitrogen-vacancy (NV) centers in diamond deliver a measurement of magnetic fields with 10× more precision than current state-of-the-art techniques. This boost in sensitivity could improve existing techniques for magnetically sensing and mapping brain activity in disorders such as

DURHAM, N.C., Nov. 2, 2018 — Researchers at Duke University used optical coherence tomography angiography (OCTA), a noninvasive imaging technique, to show that the small blood vessels in the retina at the back of the eye are altered in patients with Alzheimer’s disease. The...
Nanoscope’s 3D Superresolution Reveals Alzheimer’s Source
WEST LAFAYETTE, Ind., July 17, 2018 — A superresolution nanoscope could enable 3D imaging of amyloid plaques — a characteristic feature of Alzheimer’s disease — with up to 10 times greater detail than conventional microscopes. Researchers at Purdue University combined active shaping of...
Label-Free Imaging Maps Brain Changes in Alzheimer's Mouse Model
WUHAN, China, Oct. 20, 2017 — An imaging system called cryo-micro-optical sectioning tomography (cryo-MOST) could help speed new drug development for Alzheimer’s disease by offering a better way to monitor the brain changes indicative of Alzheimer's in mouse models....
Light Therapy Shown to Reduce Plaques in Mice with Alzheimer’s
CAMBRIDGE, Mass., Dec. 21, 2016 — Using LEDs that can be programmed to flicker at different frequencies on mouse models genetically programmed to develop Alzheimer’s, researchers are exploring the potential of using light to reduce amyloid-β (Aβ) plaque levels and to...
Neurovision Receives Financing for Retinal Imaging Technology
SACRAMENTO, Calif., July 11, 2016 — Imaging and diagnostic solutions provider Neurovision Imaging LLC has raised financing for regulatory approval of its retinal imaging technology for the early detection and monitoring of Alzheimer’s-related amyloid pathology.
Optogenetic Technique Recovers Lost Memories in Alzheimer Mouse Model
CAMBRIDGE, Mass., April 1, 2016 — An experimental optogenetics technique has been applied to a mouse model of Alzheimer’s disease (AD) to rescue memories. The study revealed that spines — small knobs on brain-cell dendrites through which synaptic connections are formed...
Clinicians Demand More From Optical Devices
Sep 14, 2015 — From the ubiquity of smartphones to an aging population, the modern world offers the optical sector a wealth of opportunities to innovate for the health care sector. Optical technologies have a long history of providing a rapid and noninvasive way...
CEO to Lead Cognoptix Board of Directors
ACTON, Mass., Oct. 14, 2014 — Medical imaging device developer Cognoptix has named its president and CEO, Paul D. Hartung, chairman of the company's board of directors.
Can Lasers Cure Alzheimer’s Disease?
GOTHENBURG, Sweden & WROCLAW, Poland, Nov. 4, 2013 — The malfunctioning protein structures that cause diseases such as Alzheimer’s and Parkinson’s can be found using just laser light, a team in Sweden and Poland has discovered. Researchers at Chalmers University of Technology in Sweden and...
Lab Combines Light, Electron Microscopy Devices
WARSAW, Poland, Aug. 21, 2013 — Nencki Institute’s new Neurobiology Centre has installed a combination of light and electron microscopy devices to help researchers better understand the structure, function and capabilities of the human brain. The center’s Laboratory of...
System Images as Mice Scurry
NEWPORT NEWS, Va., April 10, 2013 — A system that acquires functional images of the brains of mice while they scamper about could provide unprecedented insight into diseases such as Alzheimer’s, autism and drug addiction.
Color-Coded Markers Diagnose Disease Through Eyes
SAN DIEGO, Aug. 17, 2012 — New fluorescent probes that change color when they encounter brain disease markers found in the eye could offer a simpler way to identify neurodegenerative disease and distinguish between closely related disorders such as Parkinson’s, Alzheimer’s...
