Whether its the look of love, happiness, or the look of fear, humans use facial expressions to communicate important information to one another. But which parts of the brain read these cues, and how do they do it? A paper in this weeks Nature by a group of international scientists, including Professor Philippe Schyns from the University of Glasgow, offers new insights into how we recognize fear in peoples eyes.
The study focuses on a case study of a 38-year-old woman with rare bilateral damage to her amygdala - an almond-shape part of the brain in the temporal lobe. Unusually, she is completely unable to recognize fear from facial expressions - this deficit though can be rescued by instructing her to concentrate her attention on the persons eyes. The researchers found, however, that the woman (named SM in the study) only succeeded in directing her gaze to the eye regions of facial images when given explicit reminders.
SM’s problem is that although she can physically see facial features, she can’t recognise the emotion of fear. SMs impairment stems from an inability to make normal use of information from the eye region within faces when judging emotions, although she can read emotions from the mouth. Her selective impairment in recognizing fear is explained by the fact that that the eyes are the most important feature for identifying fear. However, the subject’s recognition of fearful faces became entirely normal when she was instructed to look at the eyes.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...
A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
