Many people find it very difficult to think in terms of abstractions and are much more comfortable thinking in terms of specific instances....
متن کاملReverse optical trawling for synaptic connections in situ.
We introduce a new method to unveil the network connectivity among dozens of neurons in brain slice preparations. While synaptic inputs were whole cell recorded from given postsynaptic neurons, the spatiotemporal firing patterns of presynaptic neuron candidates were monitored en masse with functional multineuron calcium imaging, an optical technique that records action potential-evoked somatic ...

The authors provide the reasons for systematically extracting these communities: they are good information sources, they provide insight into the intellectual evolution of the web and are useful for purposes of targeted advertising. An important reason that the authors fail to mention is that these communities can help researchers interested in a particular area of research discover/become awar...
