39. Central pattern generator
Elements of the central pattern generator are revealed by
electrical stimulation of high-threshold cutaneous and muscle
afferents (flexor reflex afferents, FRA) in spinal cats treated with
L-DOPA (L-dihydrox-yphenylalanine) and nialamide

40. Sensory Feedback for walking
A. Oscillating movements around
the hip joint in an immobilized
decerebrate cat
B. Stretching the detached hip
flexor muscle (iliopsoas) in a
walking decerebrate cat causes
inhibition of extensor activity and
an earlier onset of flexor activity.
