The red indicates high firing.
These recordings demonstrated that action potentials propagate faithfully, even at very high firing rates.
Combined EEG/calcium imaging experiments confirmed that neurons in mutant mice have abnormally high firing and synchrony during sleep/rest.
Object motion sensitive (OMS) neurons in the retina are highly sensitive to this scenario and signal to the brain using high firing rates.
The magic, it turned out, was nothing more than a combination of the high firing temperature and the right proportion of ingredients, including kaolin, a white clay.
The pots are fired in outdoor bonfires using dried sheep manure as fuel, which produces the high firing temperatures necessary to give the ceramic work its rich orange blush.
First, they showed that a single cell could work two different muscles: a high firing rate triggered the wrist to flex, while a low firing rate caused it to extend.
Put it this way: At this point, the U.S. economy is suffering from low hiring, not high firing, so things don't look so bad — as long as you're willing to write off the unemployed.
In follow-up experiments, we challenged the neurons to respond to their own synthetic stimuli after we introduced changes in size, position and rotation, and found that the neurons had limited invariance, showing high firing rate variability across the transformed synthetic images relative to those for transformed natural images.
Finely controlled glazes and enamel polychromy, which required the use of kaolin clay and controlled high firing, were still technically beyond Japanese capabilities; but the high regard in which the elegantly simple Chinese ware was held caused connoisseurs to elevate the status of once humble works and to commission Japanese interpretations of continental ware in Japanese kilns.
The simplest explanation for this asymmetry would be that the cells in the NAc that drive consumption behavior have high firing rates during limited access ethanol consumption; decreasing firing rates would thus decrease consumption, but increasing them further would have no effect.
