Discussions of motor behavior have traditionally focused on how a nervous system controls a body. However, it has become increasingly clear that a broader perspective, in which motor behavior is seen as arising from the interaction between neural and biomechanical dynamics, is needed. This chapter reviews a line of work aimed at exploring this perspective in a simple model of walking. Specifica...

Understanding how and why behavioral traits diversify during the course of evolution is a longstanding goal organismal biologists. Historically, this topic examined from an ecological perspective, where thought to occur in response selection pressures that arise through different social environmental factors. Yet physiology biomechanics also play role process by defining types are more or less ...

71 words) C. elegans locomotion is a stereotyped behavior that is ideal for genetic analysis. We integrated video microscopy, image analysis algorithms, and fluid mechanics principles to describe the C. elegans swim gait. Quantification of body shapes and external hydrodynamics, and model-based estimates of biomechanics reveals that mutants affecting similar biological processes exhibit related...

OBJECTIVE To determine clinical features and outcome in dogs and cats with obsessive-compulsive disorder (OCD). DESIGN Retrospective study. ANIMALS 103 dogs and 23 cats. PROCEDURES Records of patients with OCD were analyzed for clinical features, medication used, extent of behavior modification, and outcome. RESULTS Most dogs affected with OCD had been obtained from breeders. Male dogs ...

Title of Document: DESIGN OF COMPLIANCE ASSISTED GAITS FOR A QUADRUPEDAL AMPHIBIOUS ROBOT Andrew Richard Vogel, M.S., 2013 Directed By: Professor Satyandra K. Gupta Department of Mechanical Engineering The goal of this thesis was to develop an amphibious legged quadrupedal robot and associated gaits. Gaits of interest included walking, swimming, and smoothly transitioning between the two. Compl...
