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 ...
Physicists eye neural fly data, find formula for Zipf's law
Physicists have identified a mechanism that may help explain Zipf's law – a unique pattern of behavior found in disparate systems, including complex biological ones. The journal Physical Review Letters is pub ...
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.
How a Silly Putty ingredient could advance stem cell therapies
The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows.
The circadian clock is like an orchestra with many conductors
You've switched to the night shift and your weight skyrockets, or you wake at 7 a.m. on weekdays but sleep until noon on weekends—a social jet lag that can fog your Saturday and Sunday.
Brain process takes paper shape
A paper-based device that mimics the electrochemical signalling in the human brain has been created by a group of researchers from China.
Uncovering the 3-D structure of a key neuroreceptor
EPFL scientists reveal for the first time the 3D structure of a crucial neuroreceptor. The achievement has great implications for understanding the basic mechanism of electrical signal transmission between neurons and might ...
Visual system of marine annelids offers insights into the evolution of eyes
Larvae of the marine bristle worm Platynereis dumerilii orient themselves using light. Early in their development, these larvae swim towards the light to use surface currents for their dispersal. Older larvae ...
TrueNorth: a 'brain-like' chip to turn computing on its head
Computers and brains work in virtually opposite ways. Computers are laboriously programmed for specific tasks. Brains learn from experience and can perform a wide variety of complicated tasks that are currently ...
Neural networks that function like the human visual cortex may help realize faster, more reliable pattern recognition
Despite decades of research, scientists have yet to create an artificial neural network capable of rivaling the speed and accuracy of the human visual cortex. Now, Haizhou Li and Huajin Tang at the A*STAR ...
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 ...
Neuron circuit may enable pitch perception applications
The first FitzHugh-Nagumo neuron circuit designed to include noise and exhibit the Ghost Stochastic Resonance effect has been presented by researchers from Université de Bourgogne in France. Their circuit ...
Researchers find chemicals and neurons responsible for turning parental care on and off in mice
