Simple Feedback Networks: Central Pattern Generators an Recurrent Excitation
Dr. Larry Abbott

The goal is to describe the common themes in the process of
rhythmic motor output, as occurs in respiration, oral tasks like
chewing, licking, and whisking, and motor tasks like walking and
swimming. Two aspects of motor control are presented. First, the
general rhythmic patterns at the single cell or small network
level, and second, the interaction among oscillators to form
ungulatory motions, as occurs in swimming. The connection between
the experimental data and biophysically-based as well as abstract
models will be discussed. Particular emphasis will be placed on
four systems: gustation in the crab as an example of a network
oscillator under the control of cellular properties, swimming in
Tritonia as an example of a purely network oscillator, swimming in
the lamprey as an example of interacting network oscillators, and
respiration in the rodent as an example of a multi-state
oscillator.
