Identification of motor neurons and a mechanosensitive sensory neuron in the defecation circuitry of Drosophila larvae.

Abstract excerpt

Defecation allows the body to eliminate waste, an essential step in food processing for animal survival. In contrast to the extensive studies of feeding, its obligate counterpart, defecation, has received much less attention until recently. In this study, we report our characterizations of the defecation behavior of Drosophila larvae and its neural basis. Drosophila larvae display defecation cycles of stereotypic...
