How the brain learns during sleep
Researchers from Ruhr-Universität Bochum and the University of Bonn have investigated which activity patterns occur in the brain when people remember or forget things. They were interested in how the brain replays and stores during sleep what it had learned before. The team recorded the brain activity of epilepsy patients who had electrodes implanted into their brain for the purpose of surgical planning. One result: During sleep, the brain even reactivates memory traces that it can no longer remember later on. (2018-10-05)

Artificial intelligence: Towards a better understanding of the underlying mechanisms
The automatic identification of complex features in images has already become reality thanks to artificial neural networks. Facebook's automatic tagging system and Google's image search engine are just two examples. We know that these networks are inspired by the human brain, but their working mechanism is still mysterious. SISSA scientists propose a new approach for studying deep neural networks and shed new light on the image elaboration processes that they are able to carry out. (2019-11-27)

The size of lymph nodes and lung nodules is an important determinant of treatment and treatment success. (2013-04-17)

More freedom of movement while viewing glasses-free 3-D
3D movies have become commonplace over the last while. The black plastic stereo viewing glasses are even piling up at home. Good that glasses-free video displays for home use have become available. However, the technology is still not mature or widespread, and televisions of this kind are still too expensive. Researchers are working on solutions to change that. (2013-08-13)

'Invisible' influences reveal unconscious pathways used in visual perception
What aspects of our brain's activity are we actually aware of? Researchers investigated just how far visual signals from our eyes can penetrate into our brain's processing network without being consciously registered. They found that visual signals can actually travel farther under the radar of consciousness than many scientists had previously thought. (2005-03-28)

This image was taken at 3:38 a.m. EST on Feb. 9, 2017, when the spacecraft was 75 million miles (120 million kilometers) from Earth and 419 million miles (675 million kilometers) from Jupiter. With an exposure time of two seconds, the image renders Jupiter overexposed, but allows for enhanced detection of stars in the background. (2017-02-14)

New study reveals that ads comparing two brands are frequently ineffective
We've all seen ads claiming that one car outperforms another one, that one paper towel holds more water than another, or that one beer tastes better than another. Does comparing one brand to another really work as an effective advertising tool? The answer depends on how the consumer thinks about the ad, according to a forthcoming article in the March 2006 issue of the Journal of Consumer Research. (2006-01-30)

Screening for security
If you're looking for concealed weapons these days, you need more than x-ray machines and metal detectors. You want something that also will identify non-metallic weapons, or any other threatening object that may be concealed under clothing. Researchers at Pacific Northwest National Laboratory have developed an innovative screening technology that uses harmless, ultrahigh-frequency radio waves to penetrate clothing and can quickly identify plastic explosives and other types of weapons. (2005-08-30)

Blur's noise and distortion reversed
Errant pixels and blurry regions in a photo, whether digital or scanned, are the bane of photographers everywhere. Moreover, in vision processing research degraded photos are common and require restoration to a high-quality undegraded state. Research published this month in the International Journal of Signal and Imaging Systems Engineering could provide new insights. (2009-07-08)

It's not you that makes vision mistakes, it's your brain
It's common knowledge that things aren't always as they appear, but a new study shows our brains are complicit in our vision errors even at the earliest point in the brain's visual processing system. In an article to be featured in an upcoming issue of Nature Neuroscience, David Ress of Stanford University and David Heeger of NYU report that activity in the brain's visual cortex corresponds to what the subjects perceive, rather than what they actually see. (2003-03-12)

Judgment and decision-making: Brain activity indicates there is more than meets the eye

New super-resolution method reveals fine details without constantly needing to zoom in
Since the early 1930s, electron microscopy has provided unprecedented access to the alien world of the extraordinarily small, revealing intricate details that are otherwise impossible to discern with conventional light microscopy. But to achieve high resolution over a large specimen area, the energy of the electron beams needs to be cranked up, which is costly and detrimental to the specimen under observation. (2020-08-12)
