“…Thus, the collective dynamics create a group-level responsiveness to the environment that is absent at the individual level (19). The resulting increase in gradient-tracking ability for larger groups agrees with previous hypotheses (20,21) and could explain empirical studies showing that grouping facilitates the detection of chemical cues (22)(23)(24) and improves the accuracy of migrations that rely on such cues (25,26).…”

The capacity for groups to exhibit collective intelligence is an often-cited advantage of group living. Previous studies have shown that social organisms frequently benefit from pooling imperfect individual estimates. However, in principle, collective intelligence may also emerge from interactions between individuals, rather than from the enhancement of personal estimates. Here, we reveal that this emergent problem solving is the predominant mechanism by which a mobile animal group responds to complex environmental gradients. Robust collective sensing arises at the group level from individuals modulating their speed in response to local, scalar, measurements of light and through social interaction with others. This distributed sensing requires only rudimentary cognition and thus could be widespread across biological taxa, in addition to being appropriate and cost-effective for robotic agents.

“…It has previously been reported that adult zebrafish show a behavioral response to pheromones (Chen and Martinich, 1975;Bloom and Perlmutter, 1977;Van den Hurk et al, 1987;Van der Kraak, 1989;Hall and Suboski, 1995) and to amino acids (Steele et al, 1990(Steele et al, , 1991. Zebrafish clearly respond to alarm pheromone as well as to the amino acids, L-serine, alanine, and cysteine with characteristic attractive or aversive responses, similar to those described in other fishes (von Frisch, 1938(von Frisch, , 1941bHara, 1971Hara, , 1993.…”

To initiate a genetic analysis of olfactory development and function in the zebrafish, Danio rerio, we developed a behavioral genetic screen for mutations affecting the olfactory sensory system. First, we characterized olfactory responses of wild-type zebrafish to various odors. We found that 3-day-old juvenile zebrafish reacted to the amino acid L-cysteine with an aversive behavioral response. We isolated one mutant, laure (lre), which showed no aversive behavioral response to L-cysteine at 3 days of development, and carried out a preliminary characterization of this mutant's defects. We found that lre mutant fish were also defective in their response to L-serine and L-alanine, but not to taurocholic acid, as young adults. In addition, lre mutant fish had significantly fewer primary olfactory sensory neurons than normal, and the axons of these neurons did not form the characteristic axon termination pattern in the developing olfactory bulb. Nevertheless, the olfactory epithelium of lre mutant fish showed normal or near normal electrophysiological responses to several odorants. Our data suggest that the behavioral defects observed in the lre mutant result from the disruption of the developing olfactory sensory neurons and their axonal connections within the olfactory bulb. The isolation of the lre mutant shows that our behavior-based screen represents a viable approach for carrying out a genetic dissection of olfactory behaviors in this vertebrate model system.

“…Amino acids strongly attract fishes as food-derived odorants (Steele et al 1990(Steele et al , 1991Koide et al 2009). Zebrafish are capable of discriminating between different amino acids (Miklavc and Valentincic 2012).…”

The Olfactory System

Similar to other animal species, fishes efficiently use the sense of smell for locating food, detecting danger, communicating social information, and memorizing beneficial and detrimental conditions. This review summarizes recent advances in our knowledge of the olfactory system in the zebrafish (Danio rerio), which has become one of the most useful and important model organisms in neurobiology. Olfactory receptors belonging to the OR, V1R, V2R, and TAAR families are differentially expressed in three types of the olfactory sensory neurons (ciliated, microvillus, and crypt) in the olfactory epithelium. In the olfactory bulb, nine glomerular clusters are clearly delineated by anatomical features and molecular markers, serving as functional units important for odor information categorization, coding, and processing. Individual output neurons of the olfactory bulb project axons to a combination of four major target regions in the forebrain: the posterior zone of dorsal telencephalon, the ventral nucleus of ventral telencephalon, the posterior tuberculum, and the right habenula. Distinct modes of odor information decoding are employed by the individual olfactory centers: either nonselective or biased as well as either diffuse or convergent, which contribute to eliciting different physiological and behavioral responses. By taking advantage of its small brain, transparency of larvae, and amenability to various genetic and imaging techniques, zebrafish will pave the way toward understanding the functional organization of the olfactory system as a whole.
