The ability of animals to effectively locate and navigate toward food sources is central for survival. Here, using C. elegans nematodes, we reveal the neural mechanism underlying efficient navigation in chemical gradients. This mechanism relies on the activity of two types of chemosensory neurons: one (AWA) coding gradients via stochastic pulsatile dynamics, and the second (AWC<sup>ON</sup>) coding the gradients deterministically in a graded manner. The pulsatile dynamics of the AWA neuron adapt ...[more]
