DESCRIPTION:Natural goal-directed behaviors often involve complex sequence
 s of many stimulus-triggered components. Understanding how brain circuits 
 organize such behaviors requires mapping the interactions between an anima
 l\, its environment\, and its nervous system. Here\, we use continuous bra
 in-wide neuronal imaging to study the full performance of mating by the C.
  elegans male. We show that as each mating unfolds in its own sequence of 
 component behaviors\, the brain operates similarly between instances of ea
 ch component\, but distinctly between different components. When the full 
 sensory and behavioral context is taken into account\, unique roles emerge
  for each neuron. Functional correlations between neurons are not fixed\, 
 but change with behavioral dynamics. From the contribution of individual n
 eurons to circuits\, our study shows how diverse brain-wide dynamics emerg
 e from the integration of sensory perception and motor actions within thei
 r natural context.
