DESCRIPTION:C. elegans\, with the well-defined connectivity of the 302 neu
 rons in its entire nervous system\, offers an opportunity to dissect the f
 unction of neural circuits for learning. The "wiring diagram" has facilita
 ted the functional mapping of hard-wired circuits underlying behaviors. We
  have also identified a second type of circuits\, "the invisible wiring di
 agram"\, which regulates olfactory learning\, on the basis of peptides\, a
 nd acts in a way that is largely independent of synaptic connections. Intr
 iguingly\, our recent work has uncovered a third type of circuits\, "the t
 opographic circuits"\, which is based on the subcellular organization of t
 he synapses within individual neuronal processes. These findings together 
 underscore the computational potential of the small C. elegans nervous sys
 tem in regulating behaviors and experience-dependent plasticity.
