Newest computer neural networks can identify visual objects as well as the primate brain
For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects, which the human brain does very accurately and quickly.
Genes tell story of birdsong and human speech
His office is filled with all sorts of bird books, but Duke neuroscientist Erich Jarvis didn't become an expert on the avian family tree because of any particular interest in our feathered friends. Rather, ...
Neural 3-D compass discovered in mammalian brain
Pilots are trained to guard against vertigo: a sudden loss of the sense of vertical direction that renders them unable to tell "up" from "down" and sometimes even leads to crashes. Coming up out of a subway ...
Implanting complex multimodal fibers into the spinal column
The human brain's complexity makes it extremely challenging to study—not only because of its sheer size, but also because of the variety of signaling methods it uses simultaneously. Conventional neural ...
MRI scans show why politicians' lofty statements can fall on deaf ears
New research published in the Journal of Management confirms that unless political leaders can create a sense of community amongst voters, their inspirational messages are likely to fall on deaf ears.
Field study suggests brain size in ants adheres to specialization hypothesis
Paris-based team shows stress-cutting gear at CES
Gelatin nanoparticles could deliver drugs to the brain
Stroke victims could have more time to seek treatment that could reduce harmful effects on the brain, thanks to tiny blobs of gelatin that could deliver the medication to the brain noninvasively.
Brain structures devoted to learning, memory highly conserved in animal kingdom, suggesting common evolutionary origin
Whether you're cramming for an exam or just trying to remember where you put your car keys, learning and memory are critical functions that we constantly employ in daily life.
Affluence, not political complexity, explains the rise of moralizing world religions
The ascetic and moralizing movements that spawned the world's major religious traditions—Buddhism, Islam, Judaism, Hinduism, and Christianity—all arose around the same time in three different regions, ...
Birdsong study reveals how brain uses timing during motor activity
Timing is key for brain cells controlling a complex motor activity like the singing of a bird, finds a new study published by PLOS Biology.
Different species share a 'genetic toolkit' for behavioral traits, study finds
The house mouse, stickleback fish and honey bee appear to have little in common, but at the genetic level these creatures respond in strikingly similar ways to danger, researchers report. When any of these ...
Dogs hear our words and how we say them
When people hear another person talking to them, they respond not only to what is being said—those consonants and vowels strung together into words and sentences—but also to other features of that speech—the ...
Prehistoric conflict hastened human brain's capacity for collaboration, study says
Warfare not only hastened human technological progress and vast social and political changes, but may have greatly contributed to the evolutionary emergence of humans' high intelligence and ability to work ...
