Conscious perception is a matter of global neural networks
(Medical Xpress) -- Consciousness is a selective process that allows only a part of the sensory input to reach awareness. But up to today it has yet to be clarified which areas of the brain are responsible ...

Using precisely-targeted lasers, researchers manipulate neurons in worms' brains, take control of their behavior
In the quest to understand how the brain turns sensory input into behavior, Harvard scientists have crossed a major threshold. Using precisely-targeted lasers, researchers have been able to take over an animal's ...

Researchers discover surprising complexities in the way the brain makes mental maps
Your brain has at least four different senses of location – and perhaps as many as 10. And each is different, according to new research from the Kavli Institute for Systems Neuroscience, at the Norwegian ...

Smelling a skunk after a cold: Brain changes after a stuffed nose protect the sense of smell
Has a summer cold or mold allergy stuffed up your nose and dampened your sense of smell? We take it for granted that once our nostrils clear, our sniffers will dependably rebound and alert us to a lurking ...

One cell does it all: Sensory input to motor output in one worm neuron
Caenorhabditis elegans, with just 302 neurons, has long been considered an ideal model system for the study of the nervous system. New research, however, is suggesting that the worms' "simple" nervous system may be much m ...

Epilepsy sends differentiated neurons on the run
(Medical Xpress)—The smooth operation of the brain requires a certain robustness to fluctuations in its home within the body. At the same time, its extraordinary power derives from an activity structure ...

Neural 'synchrony' may be key to understanding how the human brain perceives
Despite many remarkable discoveries in the field of neuroscience during the past several decades, researchers have not been able to fully crack the brain's "neural code." The neural code details how the brain's ...
