The simpler nervous system of C. elegans provided the researchers with a more manageable testing ground for their instrument. Yet, it also could reveal information about how neurons work together that applies to more complex organisms. The researchers used a special type of microscope to record in 3-D both the nematodes' free movements and neuron-level calcium activity for more than four minutes.
Three-dimensional software the researchers designed monitored the position of an animal's head in real time as a motorized platform automatically adjusted to keep the animal within the field of view of a series of cameras...read more @ http://www.scitechnol.com/spine-neurosurgery.php
