In our brains, groups of neurons fire up simultaneously for just milliseconds at a time, in random rhythms, similar to twinkling lightning bugs in our backyards. New research from neuroscientists at ...
... . It turns out that humans, primates, some birds, and possibly other higher animals have mirror neurons that fire in the same pattern whether performing or just observing a task. These mirror neurons ...
... regulation. New findings that reveal the master architect behind a functioning motor neuron not only mirror this ideological shift but further point to the increasingly indisputable role of RNA as ...
... When an unexpected reward is presented to an individual, midbrain dopamine neurons fire high frequency bursts of electrical activity. Those bursts of activity allow us to learn to ...
... generated when rats move around and explore their environment. They watched how—and when—the rat's neurons fired relative to the rat's position and to the phase of the theta oscillations. They did ...
... , a
computer designed to mimic a functioning slice of a rat's brain. At
first, the virtual neurons fired only when prodded by a simulated
electrical current. But recently, that has changed.
Apparently ...
... vitro studies revealed that, after a seizure, BK channel function was enhanced — neurons fired quicker, stronger and more spontaneously. This abnormal activity might underlie the transition between ...
... electrodes record a pop every time a neuron fires, Devilbiss explains. Analyzing the complex ... stage for examining the interplay among PFC neurons, higher cognition, and the action of therapeutic drugs ...
... biology researcher Professor Jianfeng Feng said:
"We knew that these pulses arise because, during suckling, oxytocin neurons fire together in dramatic synchronized bursts. But exactly ...
... messenger system, called GABA, which dampens neural activity, helping to regulate when a neuron fires.
Mody and Maguire discovered that a GABA receptor subunit fluctuated conspicuously during ...
... on which nerve cells will talk to each other and in which time period. However, it is only applicable if the neurons fire action potentials with a frequency of less than one hertz.
Insight into ...

Probing the relation of neuronal firing rates and behavior
The finding, published ahead of print October 12 in the ...
... we have discovered is the molecular motor that moves these packages when synapses are active."
When neurons fire at the same time, their connections strengthen and a person can associate certain ...
