Gene mutation alters feeding behavior

ior in c. elegans. The researchers believe that studying such changes in molecules eventually may answer behavioral questions right down to why some people are cheerful and others are grumpy.

The scientists also concluded from studying the worms' EXP-2 channel, which is related to the human potassium channel HERG, that these similarly functioning channels, although different in structure and sequence, apparently evolved to fill the same needs in different animals.

The researchers now will try to determine if modifying the behavior of the EXP-2 channel also changes the worms' feeding behavior.
