Description
The nematode Caenorhabditis elegans memorizes various external chemicals, such as ions and odorants, during feeding. Here the authors find that C. elegans is attracted to the monosaccharides glucose and fructose after exposure to these monosaccharides in the presence of food; however, it avoids them without conditioning. The attraction to glucose requires a gustatory neuron called ASEL. ASEL activity increases when glucose concentration decreases.
