title: Gamma-motoneurone discharge patterns during fictive locomotion in the decerebrate cat.
abstract: Triceps surae gamma-motoneurones were recorded during fictive locomotion in the paralysed high decerebrate cat. Two distinctive patterns of discharge were observed which were similar to those reported for static and dynamic gamma-motoneurones during locomotion in the same preparation, but without paralysis (Murphy, Stein & Taylor, 1984). These results suggest that movement-related afferent feedback is not essential for the generation of the basic patterns of static and dynamic gamma-motoneurone activity during locomotion. The results are discussed in relation to the generation of alpha and gamma locomotor rhythms.
