Bioengineers create functional 3-D brain-like tissue
Bioengineers have created three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can be kept alive in the lab for more than two months.
Scientists create circuit board modeled on the human brain (w/ Video)
(Phys.org) —Stanford scientists have developed faster, more energy-efficient microchips based on the human brain – 9,000 times faster and using significantly less power than a typical PC. This offers ...
Intermediary neuron acts as synaptic cloaking device
Neuroscientists believe that the connectome, a map of each and every connection between the millions of neurons in the brain, will provide a blueprint that will allow them to link brain anatomy to brain function. ...
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.
Blood cells are new, unexpected source of neurons in crayfish
Researchers have strived for years to determine how neurons are produced and integrated into the brain throughout adult life. In an intriguing twist, scientists reporting in the August 11 issue of the Cell ...
Tropical cuttlefish a model organism to study travelling waves in biological systems
Some cephalopods are masters of display: Not only can they adapt their skin colour to their immediate environment, thereby merging with the background, they can also produce propagating colour waves along ...
Researchers find chemicals and neurons responsible for turning parental care on and off in mice
Discovery of quantum vibrations in 'microtubules' corroborates theory of consciousness
A review and update of a controversial 20-year-old theory of consciousness published in Physics of Life Reviews claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent ...
Glowing worms illuminate the roots of behavior
A research team at Worcester Polytechnic Institute (WPI) and The Rockefeller University in New York has developed a novel system to image brain activity in multiple awake and unconstrained worms. The technology, ...
Juvenile mice secrete a protective pheromone in their tears, blocking adult mating
Nocturnal animals need their noses to stay alive. Mice, among others, depend on their impressive olfactory powers to sniff out food or avoid danger in the dark.
Key cellular mechanism in the body's 'battery' can either spur or stop obesity
Becoming obese or remaining lean can depend on the dynamics of the mitochondria, the body's energy-producing "battery," according to two new studies by Yale School of Medicine researchers featured as the ...
Dragonflies can see by switching 'on' and 'off'
(Phys.org) —Researchers at the University of Adelaide have discovered a novel and complex visual circuit in a dragonfly's brain that could one day help to improve vision systems for robots.
Carbon nanotube harpoon catches individual brain-cell signals
Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes.
Beer compound could help fend off Alzheimer's and Parkinson's diseases
The health-promoting perks of wine have attracted the spotlight recently, leaving beer in the shadows. But scientists are discovering new ways in which the latter could be a more healthful beverage than once thought. They're ...
