Unformatted text preview: Outline of the Lecture Outline of the Lecture Models of Motor-pattern Generation Models of Motor-pattern Generation A Simple Model Computer A Simple Model Computer Simulations Simulations Models of Spinal Motor- Models of Spinal Motor- Pattern Generation Depend Pattern Generation Depend Strongly on Parameters Strongly on Parameters If the system is rectifying, and Re() > 0 and Im( ) 0, trajectories converge to limit cycles. Reduced preparations show that the motor- pattern generation circuitry is in the spinal cord. One of the best known central- pattern generators is that of the lampreys swimming; it shares properties with mammalian locomotion. Stimulation of the mesencephalic locomotion region indirectly activates and speeds walking. Swimming uses half centers, with cross inhibition ending mainly by local inhibition. Jung et al. model individual neurons with an Jung et al....
