Behavioral motifs and neural pathways coordinating O2 responses and aggregation in C. elegans.

Abstract excerpt

BACKGROUND: Simple stimuli can evoke complex behavioral responses coordinated by multiple neural circuits. O(2) is an important environmental variable for most animals. The nematode C. elegans avoids high O(2), and O(2) levels regulate its foraging and aggregation. RESULTS: Here, we dissect aggregation and responses to O(2) gradients into behavioral motifs and show how O(2) responses can promote aggregation. To...
