fNIRS Hyperscanning: A door to real-world social neuroscience research

By Yumie Ono

What is “hyperscanning”?
Recent advances in non-invasive brain activity measurement techniques have inspired social neuroscientists to simultaneously record data from two or more brains and investigate interpersonal (across-brains) neural correlates in various social situations. Such attempts began more than 50 years ago with electroencephalography (EEG) (Duane and Behrendt, 1965), and scanning two people at once was later termed a “hyperscan” in the work of Montague et al. (2002). Montague and colleagues connected two functional magnetic resonance imaging (fMRI) scanners together, and hemodynamic data from two participants were measured while they played a deception game.

A Roadside Test for Driving while High

By Meryem Yucel

Cannabis is the most frequently detected illicit drug in drivers, and can double the risk of motor vehicle accidents. Currently, cannabis testing can determine whether an individual has used cannabis recently (e.g. in the past month), but cannot detect whether a person is acutely intoxicated or impaired. Thus, it is essential to develop novel methods to detect acute cannabis impairment, applicable in the real world, including roadside settings.

Light Scan Technique Reveals Secret Writing in Mummy

By Felipe Orihuela-Espina

Collaborative work led by Prof. Adam Gibson  and Prof. Melissa Terras (University College London) using light to reveal information from Egyptian objects made the news recently. The project is a whole line of research that includes other investigators, institutions, and multiple funding sources, all focused on the further development and use of multispectral imaging for analyzing and digitizing heritage objects. Multispectral imaging is the combination of several monochromatic images from wavelengths in the ultraviolet, visible and near infrared range of the spectrum. Multispectral imaging usually refers to more than 3 images (to distinguish from “plain” color imaging) but not covering the whole spectrum (to distinguish from hyperspectral and broadband imaging).

CYRIL: Engineering Light to Monitor Metabolism

By Felipe Orihuela-Espina

Back in 1977, Jöbsis’ original intention was to measure tissue metabolism through the spectroscopic measurement of cytochrome-c-oxidase (CCO). CCO is the terminal electron acceptor responsible for catalyzing oxygen to produce ATP (over 95%) in the biochemical chain of the aerobic metabolism of glucose. In other words, CCO is an excellent biomarker of intracellular energy metabolism. Alas, detection of CCO is more challenging than for other molecules; its concentration is lower than 10% in hemoglobin and it has a broad spectral signature in the NIR range.

Featured Artist: Jenny Jeiyoun Park

By Jenny Jeiyoun Park

My art is inspired by the imagery and sentiment experienced through daily rituals and familiarities that are evoked within scientific academia, an attempt to bridge the disconnect between the spheres of art and science. The process of scientific discovery is expressed through the depiction of researchers in dynamic interaction to demystify science and to serve as a departure from the common portrayals of machines and test tubes. The characters are introduced into a semi-fictional moment created through my involvement with these people and the laboratory. As in science, where seemingly sporadic sets of data converge into the formulation of a singular hypothesis, the idiosyncratic, distinct characters are brought onto a singular large canvas to illustrate the disconnected yet collective learning process of science.
