We present a novel method for the unsupervised discovery of behavioural motifs in larval Drosophila melanogaster and Caenorhabditis elegans. A motif is defined as a particular sequence of postures that recurs frequently. The animal's changing posture is represented by an eigenshape time series, and we look for motifs in this time series. To find motifs, the eigenshape time series is segmented, and the segments clustered using spline regression. Unlike previous approaches, our method can…

Behavioural motifs of larval Drosophila melanogaster and Caenorhabditis elegans

It is argued that the ambiguity in the unsupervised discovery of behavioural motifs in larval Drosophila melanogaster and Caenorhabditis elegans is due to greater continuity between behavioural states than is generally assumed for these organisms.

Comprehensive analysis of behavioral dynamics in the protochordate Ciona intestinalis

A neuroethological approach is taken to break down the motor behavioral repertoire of one of the authors' nearest invertebrate relative, the protochordate Ciona intestinalis, into basic building blocks and reveals that Ciona swimming is rich in stereotyped behavioral motifs.

Inactivity periods and postural change speed can explain atypical postural change patterns of Caenorhabditis elegans mutants

It is proposed that elimination of inactivity periods and overall acceleration of postural change speed can explain behavioral phenotypes of strains with very atypical postural transition patterns.

Inconsistencies in C. elegans behavioural annotation

This paper investigates the consistency of annotation for the ‘Omega turn’ of C. elegans, which is a frequently used behavioural assay for this animal and reveals a substantial lack of consistency in decisions and thresholds.

Deriving Shape-Based Features for C. elegans Locomotion Using Dimensionality Reduction Methods

A data-driven approach to worm shape analysis is taken using independent component analysis (ICA), non-negative matrix factorization (NMF), a cosine series, and jPCA and it is confirmed that the dimensionality of worm shape space is close to four.

C. elegans search behavior analysis using Multivariate Dynamic Time Warping

This work proposes a novel approach that combines Multivariate Dynamic Time Warping and step-length path encoding to cluster C. elegans movement path data and shows that the proposed combination avoids the need for extracting complex path features.

Comprehensive analysis of locomotion dynamics in the protochordate Ciona intestinalis reveals how neuromodulators flexibly shape its behavioral repertoire

High-throughput video acquisition with pharmacological perturbations of bioamine signaling is combined to systematically reveal the global structure of the motor behavioral repertoire in the Ciona intestinalis larvae and shows that flexible motor module usage gives rise to diverse behaviors in response to different light stimuli.

Searching for Structure in the Social Behavior of Fruit Flies

A method for quantifying behavior of interacting fruit flies which combines high-throughput video acquisition and tracking of individuals with unsupervised learning methods for capturing an animal’s entire behavioral repertoire is introduced.

Continuous lateral oscillations as a core mechanism for taxis in Drosophila larvae

Analysis of larvae motion reveals a rhythmic, continuous lateral oscillation of the anterior body, encompassing all head-sweeps, small or large, without breaking the oscillatory rhythm, which provides a simple architecture for combining information across modalities, and explaining how learnt associations modulate taxis.



A dictionary of behavioral motifs reveals clusters of genes affecting Caenorhabditis elegans locomotion

It is shown that four basic shapes, or eigenworms, previously described for wild-type worms, also capture mutant shapes, and that this representation can be used to build a dictionary of repetitive behavioral motifs in an unbiased way.

Mechanistic analysis of the search behaviour of Caenorhabditis elegans

The results show how movement strategies arise from a balance between intrinsic and extrinsic mechanisms, that search behaviour in C. elegans is initially determined by expectations developed from previous environmental experiences, and which reorientation behaviours are modified as information is acquired from new environments.

Mapping the stereotyped behaviour of freely moving fruit flies

A method for mapping an animal's actions, relying only upon the underlying structure of postural movement data to organize and classify behaviours, finds that flies perform stereotyped actions roughly 50% of the time, discovering over 100 distinguishable, stereotyped behavioural states.

Sensorimotor structure of Drosophila larva phototaxis

This work defines the algorithms for Drosophila larva phototaxis by quantifying the movements of individual animals responding to a battery of illumination conditions and finds that specific sensorimotor pathways that govern distinct light-evoked responses begin to segregate at the first relay after the photosensory neurons.

Characterization of Drosophila Larval Crawling at the Level of Organism, Segment, and Somatic Body Wall Musculature

This work lays a foundation for use of Drosophila larva as a model system for studying the genetics and development of rhythmic behavior and quantified crawling at the organism, segment, and muscle levels.

Dimensionality and Dynamics in the Behavior of C. elegans

It is shown that the space of shapes adopted by the nematode Caenorhabditis elegans is low dimensional, with just four dimensions accounting for 95% of the shape variance, and Stimulus-dependent correlations among the different modes suggest that one can generate more reliable behaviors by synchronizing stimuli to the state of the worm in shape space.

Forward locomotion of the nematode C. elegans is achieved through modulation of a single gait

A smooth transition from swimming to crawling is revealed, marked by a linear relationship between key locomotion metrics, and it is shown that environmental forces play only a small role in determining the shape of the worm, placing conditions on the minimal pattern of internal forces driving locomotion.
