1.3 C. elegans sensory system C. elegans is a simple multicellular organism‚ and‚ like other animals‚ it constantly perceives environmental cues and elicits appropriate physiological responses. Remarkably‚ this process is achieved with only a small number of neurons. An adult C. elegans hermaphrodite nervous system harbors 302 neurons‚ which have been grouped into 118 distinct classes according to their topology and synaptic connection pattern (Ward‚ 1975 #4;Sulston‚ 1977 #8;Sulston‚ 1983 #9;Ward
