FEATURES
Laser Therapy Reaches Hard-to-Treat Epilepsy For decades, the most commonly used treatments for epilepsy were pharmaceuticals or resection surgery, which involves removing a segment of brain tissue from where the patient’s seizures originate....
Neurophotonic Techniques Shed New Light on Traumatic Brain Injury Traumatic brain injury can have catastrophic impacts on everyday functioning and quality of life. Now, a set of photonic tools may provide fresh insights into this condition. Along with the technical...
Biomedical Research, Innovation to Take Center Stage at SPIE BiOS A rapid-fire Hot Topics session featuring talks on the latest in biomedical optics, from live analysis of embryonic development to deep learning-enabled optics, will be a centerpiece at SPIE BiOS...
Two-Photon Imaging Monitors Brain Synapses During Prolonged Anesthesia The formation of synapses in the circuitry of the brain, and especially the solidification and disappearance of synaptic structures, mediates how people learn, memorize, and forget. Since the...
Fluorescence Lifetime Imaging Reveals the Cutting Edge in Cancer Surgery Fluorescence lifetime imaging (FLIm) is an optical spectroscopic technique that is well suited to interrogating biological tissues in vivo. By measuring the time-resolved fluorescence properties...
NIR Spectroscopy Captures the Impacts of Stroke Every year, approximately 5.5 million people worldwide lose their lives to stroke. According to the Centers for Disease Control and Prevention, stroke-related costs in the U.S. total nearly $50...
EDITORIAL
Lasers on the brain Existing treatments, such as laser ablation, and therapies currently in research and development both hold promise for patients and clinicians who seek to successfully cross the divide between living with epileptic seizures and experiencing an improved quality of life. Laser-based techniques also present a viable alternative to traditional, often risky, resection surgery, in which a portion of...

Microscopy Method Enables Deep In Vivo Brain Imaging A method developed by the Prevedel Group at the European Molecular Biology Laboratory (EMBL) allows neuroscientists to observe live neurons deep within the brain — or any other cell hidden within an opaque tissue. The method is based on three-photon microscopy and adaptive optics. The method increases the ability of scientists to observe astrocytes generating calcium waved in deep layers of...
Dyeless Method Maps Blood Flow in Brain Down to Single Cell Researchers from the Skolkovo Institute of Science and Technology (Skoltech) and Saratov State University developed an inexpensive method of visualizing blood flow in the brain, one that avoids the...
OSA Changes Name to Optica The professional society in optics and photonics formerly known as The Optical Society (OSA) has changed its name to Optica, the Society advancing optics and photonics worldwide. The global...
Injectable Biosensors Convert Brain Activities into Detectable Optical Signals Technology for monitoring neuronal activity noninvasively could allow scientists to study the brain without the need for surgery or implanted devices. The newly developed nanotechnology, called...
Optical Technique Measures Chirality Over Broad Wavelength Range A research team from Politecnico di Milano and the University of Bayreuth (Germany) has developed an approach for the quick measurement of chirality across a broad wavelength range. In molecules,...
3 Combined Techniques Boost Imaging Precision Researchers from the University of Illinois Urbana-Champaign, working with domestic and international collaborators, have combined three imaging techniques to detect the timing and location of brain...
Photoacoustic Technology Images Brain with Laser Light Caltech professor Lihong Wang has demonstrated a technology capable of imaging the human brain with laser light and ultrasonic sound waves. The technology is known as PACT, for photoacoustic...
3 QUESTIONS
3 Questions with Euiheon Chung BioPhotonics spoke with Euiheon Chung, a biomedical science and engineering professor at Gwangju Institute of Science and Technology in South Korea. Chung and his colleagues recently published a paper (www.doi.org/10.1364/ optica.422871) about the use of a technique called optical speckle image velocimetry to quantitatively measure blood flow in the cortical brain as an indicator of health or...
BIOPINION
Photostimulation provides an alternative to medication Clinicians have long sought to understand the physiological causes of brain dysfunction. The adverse effects are sometimes attributed to traumatic brain injury or to aging. While some of the dysfunctional processes are becoming better understood, much is still to be learned about treatment and prevention of lasting effects on the brain from accidents or illnesses. It is time for doctors and...
POST SCRIPTS
Researchers go eye to eye with octopuses The loss of macular pigment is a precursor to macular degeneration, a disorder that afflicts millions every year. Historically, there has been no easy way to test for loss of pigment as part of a traditional eye examination. Researchers at the University of Bristol in England found a way to help identify risk in humans by studying octopuses captured during low tide on coral reefs around Lizard...
