so the neurons don't have their command center, and it happens without stimulation; it just happens on its own," Kaeser said. "This is spontaneous local triggering of dopamine release." ...

Here we show that in freely behaving rats after a long period in an awake state, cortical neurons can go briefly ‘offline’ as in sleep, accompanied by slow waves in the local EEG. Neurons ...

Neurons can use local stores for communication needs Date: May 26, 2014 Source: Rockefeller University Press Summary: Neurons can utilize a supremely localized internal store of calcium to ...

Connectivity mapping revealed a streamlined architecture: nearly 50,000 local neurons feed into 4,500 projection neurons, which transmit visual information to the central brain through 352 ...

However, exploring the brain may help in understanding the bigger picture. The brain is primarily composed of neurons, which are cells that generate electrical impulses for communication.

“Rather than originating from glia, the new dopamine cells came from local, existing mature neurons without passing through a stem cell state,” Dr. Zhang states. “This is a mature-cell-to ...

The exact origin of GABAergic (γ-aminobutyric-acid-releasing) interneurons, which are responsible for control the firing of the principal human cortical neurons, has remained unclear. In rodents all ...

Their findings imply local sharing of resources: a local ‘neighborhood’ of synapses. Neurons constantly process information from thousands of synapses. Numerous synapses populate large volumes ...

Before the connectome was available, neuroscientists weren't sure if inhibitory neurons target specific cells in a given network, rather than just affecting local neurons that happen to be in ...

The brain is solving a global problem, optimizing for survival, and yet neurons must learn from only local information received at their synapses. Furthermore, the brain must "get better" without ...
