A major challenge in analyzing animal behavior is to discover some underlying simplicity in complex motor actions. Here, we show 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. These dimensions provide a quantitative description of worm behavior, and we partially reconstruct “equations of motion” for the dynamics in this space. These dynamics have multiple attractors, and we find that… 
The emergence of long timescales and stereotyped behaviors in C. elegans
TLDR
The stochastic dynamics of the crawling behavior of the nematode C. elegans are used to show that the noise amplitude decreases systematically with increasing time away from food, resulting in longer bouts of forward crawling and suggesting that worms can use noise to adaptive benefit.
The emergence of stereotyped behaviors in C. elegans
TLDR
A simple stochastic model for the worm's continuously changing body shape during crawling generates reversals at a rate within error bars of that observed experimentally, and the relatively stereotyped trajectories in the neighborhood of the reversal also are predicted correctly.
Sampling the movement phenospace: Towards a biophysics of behavior in the wiggling of C. elegans.
We apply a low-dimensional yet complete representation of body shape (eigenworms, [1]) to construct a principled parameterization of the 2D movement behavior of the nematode C. elegans. Despite it’s
Capturing the Continuous Complexity of Behavior in C. elegans
TLDR
This work develops a behavioral state space in which the full instantaneous state is smoothly unfolded as a combination of short-time posture dynamics, tailored to multivariate observations and extends previous reconstructions through the use of maximal prediction.
Emergence of long timescales and stereotyped behaviors in Caenorhabditis elegans
TLDR
The stochastic dynamics of the crawling behavior of the nematode Caenorhabditis elegans are used to show that the noise amplitude decreases systematically with increasing time away from food, resulting in longer bouts of forward crawling and suggesting that worms can use noise to modify their locomotory behavior.
Modeling the ballistic-to-diffusive transition in nematode motility reveals variation in exploratory behavior across species
TLDR
This work broadly sample the nematode behavioral repertoire by measuring motile trajectories of the canonical lab strain C. elegans N2 as well as wild strains and distant species, and finds that salient features of the motility statistics are captured by a random walk model with independent dynamics in the speed, bearing and reversal events.
From Modes to Movement in the Behavior of Caenorhabditis elegans
TLDR
A map is constructed from the dynamics in this shape space to the trajectory of the worm along the agar to illustrate that changes in the continuous dynamics reveal subtle differences in movement strategy that occur among mutants defective in two classes of dopamine receptors.
Modeling the ballistic-to-diffusive transition in nematode motility reveals low-dimensional behavioral variation across species
A quantitative understanding of organism-level behavior requires predictive models that can capture the richness of behavioral phenotypes, yet are simple enough to connect with underlying mechanistic
Capturing the continuous complexity of behaviour in Caenorhabditis elegans
Animal behaviour is often quantified through subjective, incomplete variables that mask essential dynamics. Here, we develop a maximally predictive behavioural-state space from multivariate
Nonlinear Control in the Nematode C. elegans
TLDR
A global, nonlinear control model which is minimally parameterized and captures the state transitions described by Markov-switching models with a single dynamical system is proposed, providing an elegant characterization of control in the neuron population dynamics in C. elegans.

Sensorimotor control during isothermal tracking in Caenorhabditis elegans
TLDR
It is shown that sensorimotor control during isothermal tracking may be summarized as a strategy in which the worm changes the curvature of its propulsive undulations in response to temperature changes measured at its head, and that a concise mathematical model for this strategy is consistent with the exquisite stability of the worm's isothermal alignment in spatial thermal gradients.
A Computational Model for C. elegans Locomotory Behavior: Application to Multiworm Tracking
TLDR
The algorithm can track worms of diverse sizes and conformations in the presence of imaging artifacts and clutter, even when worms are overlapping with others, and provides the basis for reliable morphometric and locomotory analysis of freely behaving worm populations.
Neuronal substrates of complex behaviors in C. elegans.
TLDR
This work has identified gene products required for nervous system function and elucidated the molecular and neural bases of behaviors in the nematode Caenorhabditis elegans.
Machine vision based detection of omega bends and reversals in C. elegans
TLDR
A novel algorithm to automatically detect omega bends is described, which relies in part on a new method for obtaining a morphological skeleton describing the body posture of coiled worms, and an optimized algorithm to detect reversals is presented, which showed improved performance over previously described methods.
The Fundamental Role of Pirouettes in Caenorhabditis elegans Chemotaxis
TLDR
It is suggested that chemotaxis is produced by a series of pirouettes that reorient the animal to the gradient, and the pirouette model of C. elegans chemot axis is sufficient and general.
Step-Response Analysis of Chemotaxis in Caenorhabditis elegans
TLDR
A comprehensive characterization of the sensorimotor transformation underlying Caenorhabditis elegans chemotaxis as obtained by inducing stepwise temporal changes in attractant concentration within the substrate as the worm crawls across it found that the step response is complex, with multiple phases and a nonlinear dependence on the sign and amplitude of the stimulus.
Computer-driven automatic identification of locomotion states in Caenorhabditis elegans
Step Response Analysis of Thermotaxis in Caenorhabditis elegans
TLDR
Overall, however, turning probability was modulated in a manner consistent with a role for turning behavior in thermal migration, suggesting that sensory systems for thermotaxis and chemotaxis may converge on a common behavioral mechanism.
An automated system for measuring parameters of nematode sinusoidal movement
TLDR
A user-friendly system to analyze nematode movement in an automated and quantitative manner and a comparison of movement parameters for a small set of mutants affecting the Go/Gq mediated signaling network that controls acetylcholine release at the neuromuscular junction is reported.
