Neuronal networks in the turtle spinal cord have considerable computational complexity
even in the absence of connections with supraspinal structures. These networks contain …

The precise coordination of body parts is essential for survival and behavior of higher
organisms. While progress has been made towards the identification of central mechanisms …

Motor systems must adapt to perturbations and changing conditions both within and outside
the body. We refer to the ability of a system to maintain performance despite perturbations as …

Background A classic sign of canine syringomyelia (SM) is scratching towards one shoulder.
Using magnetic resonance imaging (MRI) we investigate the spinal cord lesion relating to …

Homeostasis occurs in a control system when a quantity remains approximately constant as
a parameter, representing an external perturbation, varies over some range. Golubitsky and …

Mutually inhibitory populations of neurons, half-center oscillators (HCOs), are commonly
involved in the dynamics of the central pattern generators (CPGs) driving various rhythmic …

Using a simulation approach, we propose a biophysically feasible mechanism describing
how a multifunctional central pattern generator (CPG) can produce co-existing slow and fast …

Developing spinal motor networks produce a diverse array of outputs, including episodic
and continuous patterns of rhythmic activity. Variation in excitability state and …

We present an analysis of activity patterns in a neuronal network that consists of three
mutually inhibitory neurons with voltage-sensitive piecewise smooth coupling. This network …

Physiological systems underlying vital behaviors, such as breathing, walking, and feeding,
are controlled by closed-loop systems integrating central neural circuitry, biomechanics, and …
