Neuronal filters for broadband information transmission in the brain
(Medical Xpress) -- As in broadband information technology, the nervous system transmits different messages simultaneously from one brain region to others. But how are messages retrieved at the other end without ...

Sensory experience and rest control survival of newborn neurons in adults
When it comes to the circuits that make up the olfactory system, it seems that less is more. Much like the addition and elimination of extra synapses that helps fine-tune brain circuitry, the olfactory system continues to ...

Major discovery explains how adult brain cleans out dead brain cells, produces new ones
(Medical Xpress) -- Adult brains generate thousands of new brain cells called neurons each day; however only a small fraction of them survive. The rest die and are consumed by scavenger cells called phagocytes. Until now, ...
