Traumas like Sept. 11 make brains more reactive to fear

...tric disorders. "We know that looking at fearful faces in normal adults tends to activate the amygdalae relative to looking at neutral faces," said Ganzel. "So we were looking to see if people who have had a very bad experience would have more response to this relatively mild everyday stimulus." Indeed...

Diminishing dinosaur steps saved by laser and laptop

...d firing laser beams, which reflect off the quarry faces back to a receiver. The device then cross references the reflections with a built-in digital camera and GPS, and feeds the information into an attached laptop. Software is then used to create a detailed and very accurate 3D computer model of the loca...

Mimicking how the brain recognizes street scenes

...lasses. For instance, systems engineered to detect faces or recognize textures are poor at detecting cars. In the biological model, the same algorithm can learn to detect widely different types of objects. To test the model, the team presented full street scenes consisting of previously unseen examples...

New study challenges 'critical period' in childhood vision development

The very simple control scheme proposed takes into account 70 years of often surprising observations of the behavior of winged insects. ...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...Riesenhuber. "It's like if a person had never seen faces before, they would all look similar at first." In the first experiment, the participants looked at series of cars presented at different parts of the screen and performed simple position judgments on the images, while their brain activity was bein...

Stem cell therapy shows promise for rescuing deteriorating vision

..., robbing people of the ability to read, recognize faces and live independently. The finding that the brain cells protected the cells in the eye was a surprise, according to Raymond D. Lund, an author of the new study and an eye disease expert at the University of Utah and the Oregon Health and Sciences...

A potential biological cause for sudden infant death syndrome

...d sleep. When babies sleep face-down or have their faces covered by bedding, they are thought to re-breathe exhaled carbon dioxide, therefore breathing in less oxygen. Normally, the rise in carbon dioxide activates nerve cells in the brainstem, which in turn stimulate respiratory and arousal centers in the...

Fishy cooperation

...perspective focused on the tasks that each species faces in nature. In this regard, these two reef predators show us that if it comes to survival, highly intelligent solutions are within the reach of animals as different from us as fish. (Watch a grouper signal to a giant moray eel resting in a cave by sha...

Coral stress 'like never in history'

...l reefs of the Huon Peninsula, which are now cliff faces rising up to 25 metres above the beach, A/Prof. Pandolfi and his team were able to see where large scale disturbances had occurred in the history of these reefs which dated back as far as 11 000 years ago. "The sequence of fossils is like a three ...

"Although Mongolia faces stiff conservation challenges as it transitions to a free-market economy, the saiga can easily emerge as a success story with a little scientific input and support for local communities" offers Joel Berger, project co-director and Senior Scientist wi...

Scientists solve 30-year-old mystery of mutant mouse's kidney woes

...entrated on the side of collection duct cells that faces the urine, where aqp2 can extract water from the waste stream for recirculation in the body. In the mutant mice, though, aqp2 was scattered around the collection duct cells. "The protein is still there, but it's not in the right place," Chen says. ...

Tests for 'face-blindness' reveal disorder may not be so rare

Fertility hope as study shows eggs survive in older ovaries

Pure novelty spurs the brain

...this series four types of different, or "oddball," faces or scenes. One oddball was simply a different neutral image, one was a different image that required the researchers to press a button, one was an emotional image, and one was a distinctly novel image. In fMRI, harmless radio signals and magnetic fie...
