“…First, as shown clearly by moths, insects often combine zigzagging through an odour plume while approaching its source and wide 'casting' movements to search for the trail whenever they lose it 8,9 . The zigzagging approach has been observed in several other animals including bees, cockroaches, dogs and humans 5,[10][11][12] . Second, the use of stereo olfaction in efficiently performing this task has been repeatedly suggested.…”

Rats track odour trails accurately using a multi-layered strategy with near-optimal sampling

Tracking odour trails is a crucial behaviour for many animals, often leading to food, mates or away from danger. It is an excellent example of active sampling, where the animal itself controls how to sense the environment. Here we show that rats can track odour trails accurately with near-optimal sampling. We trained rats to follow odour trails drawn on paper spooled through a treadmill. By recording local field potentials (LFPs) from the olfactory bulb, and sniffing rates, we find that sniffing but not LFPs differ between tracking and non-tracking conditions. Rats can track odours within ~1 cm, and this accuracy is degraded when one nostril is closed. moreover, they show path prediction on encountering a fork, wide 'casting' sweeps on encountering a gap and detection of reappearance of the trail in 1-2 sniffs. We suggest that rats use a multi-layered strategy, and achieve efficient sampling and high accuracy in this complex task.

“…Once animals receive an odorant, they move upstream to track it (surge), and if they lose the odorant, they move across the stream (casting) or change their direction to recontact it (Vickers, 2000;Willis, 2008). Insects are useful models for studying odour tracking as they display this fundamental strategy in both walking (Tobin, 1981;Tobin and Bell, 1986;Willis and Avondet, 2005) and flying (Kennedy and Marsh, 1974;Kennedy, 1983;Willis and Baker, 1987;Baker and Vogt, 1988;Mafra-Neto and Carde, 1994;Vickers and Baker, 1994;Budick and Dickinson, 2006;van Breugel and Dickinson, 2014).…”

A simple behaviour provides accuracy and flexibility in odour plume tracking—the robotic control of sensory-motor coupling in silkmoths

Odour plume tracking is an essential behaviour for animal survival. A fundamental strategy for this is to move upstream and then acrossstream. Male silkmoths, Bombyx mori, display this strategy as a preprogrammed sequential behaviour. They walk forward (surge) in response to the female sex pheromone and perform a zigzagging 'mating dance'. Though pre-programmed, the surge direction is modulated by bilateral olfactory input and optic flow. However, the nature of the interaction between these two sensory modalities and contribution of the resultant motor command to localizing an odour source are still unknown. We evaluated the ability of the silkmoth to localize an odour source under conditions of disturbed sensory-motor coupling, using a silkmoth-driven mobile robot. The significance of the bilateral olfaction of the moth was confirmed by inverting the olfactory input to the antennae, or its motor output. Inversion of the motor output induced consecutive circling, which was inhibited by covering the visual field of the moth. This suggests that the corollary discharge from the motor command and the reafference of selfgenerated optic flow generate compensatory signals to guide the surge accurately. Additionally, after inverting the olfactory input, the robot successfully tracked the odour plume by using a combination of behaviours. These results indicate that accurate guidance of the reflexive surge by integrating bilateral olfactory and visual information with innate pre-programmed behaviours increases the flexibility to track an odour plume even under disturbed circumstances.
