    ..Description of the normal pattern of cholinergic proteins and neurons will improve our understanding of the role of cholinergic neurons in the behavior and development of this model organism. ..

    ..The temporal correlation of these events may mean that a common unc-4-dependent mechanism controls both the specificity of synaptic inputs as well as the strength of synaptic outputs for these motor neurons. ..

    ..These results suggest that aging in C. elegans is slowed through neuronal and endocrine response to space environmental cues. ..

    ..We have identified complementary elements at comparable locations in the genomes of representative species of other animal phyla; we suggest that this unusual regulatory mechanism may be a general feature of CGLs. ..

    ..The Km for each substrate is also affected by salt, but in different manners from each other and the Vmax; the kinetic parameter Vmax/Km thus changes significantly as a function of the salt concentration. ..

    ..Using a dyn-1::lacZ gene fusion, a high level of dynamin expression was observed in motor neurons, intestine, and pharyngeal muscle. Our results suggest that dyn-1 function is required during development and for normal locomotion. ..

    ..This microcircuit motif is common in the C. elegans nervous system, as well as in the mammalian cortex; thus, understanding its functional properties in C. elegans may provide insight into its computational role in more complex brains. ..
