A fear conditioned cue orchestrates a suite of behaviors in rats

eLife
Pavlovian fear conditioning has been extensively used to study the behavioral and neural basis of defensive systems. In a typical procedure, a cue is paired with foot shock, and subsequent cue presentation elicits freezing, a behavior theoretically ...

The Parallel Worm Tracker: a platform for measuring average speed and drug-induced paralysis in nematodes.

PLoS ONE, 2008
BackgroundCaenorhabditis elegans locomotion is a simple behavior that has been widely used to dissect genetic components of behavior, synaptic transmission, and muscle function. Many of the paradigms that have been created to study C.

Hand and foot pressures in the aye-aye (Daubentonia madagascariensis) reveal novel biomechanical trade-offs required for walking on gracile digits [PDF]

, 2010
Arboreal animals with prehensile hands must balance the complex demands of bone strength, grasping and manipulation. An informative example of this problem is that of the aye-aye (Daubentonia madagascariensis), a rare lemuriform primate that is unusual ...

Odor-identity dependent motor programs underlie behavioral responses to odors

eLife, 2015
All animals use olfactory information to perform tasks essential to their survival. Odors typically activate multiple olfactory receptor neuron (ORN) classes and are therefore represented by the patterns of active ORNs.

The Geometry of Locomotive Behavioral States in C. elegans

PLoS ONE, 2013
We develop a new hidden Markov model-based method to analyze C elegans locomotive behavior and use this method to quantitatively characterize behavioral states. In agreement with previous work, we find states corresponding to roaming, dwelling, and quiescence. However, we also find evidence for a continuum of intermediate states.

Statistical structure of locomotion and its modulation by odors

eLife, 2019
Most behaviors such as making tea are not stereotypical but have an obvious structure. However, analytical methods to objectively extract structure from non-stereotyped behaviors are immature.

Live Demonstration: neuromorphic robotics, from audio to locomotion through spiking CPG on SpiNNaker. [PDF]

, 2019
This live demonstration presents an audio-guided neuromorphic robot: from a Neuromorphic Auditory Sensor (NAS) to locomotion using Spiking Central Pattern Generators (sCPGs). Several gaits are generated by sCPGs implemented on a SpiNNaker board.

Bayesian Optimization Using Domain Knowledge on the ATRIAS Biped

, 2017
Controllers in robotics often consist of expert-designed heuristics, which can be hard to tune in higher dimensions. It is typical to use simulation to learn these parameters, but controllers learned in simulation often don't transfer to hardware.

EVOLVING NEURAL CONTROLLERS FOR TERRESTRIAL AND EXTRATERRESTRIAL LOCOMOTION IN AN ARTIFICIAL QUADRUPED

Journal of ICT, 2005
This study explores the use of a multi-objective evolutionary algorithm for the automatic synthesis of neural controllers for the quadrupedal locomotion of an artificial creature in a 3-dimensional, physics-based environment.

A pair of ascending neurons in the subesophageal zone mediates aversive sensory inputs-evoked backward locomotion in Drosophila larvae.

PLoS Genetics, 2020
Animals typically avoid unwanted situations with stereotyped escape behavior. For instance, Drosophila larvae often escape from aversive stimuli to the head, such as mechanical stimuli and blue light irradiation, by backward locomotion.
