Understanding Central Pattern Generators: Insights Gained from the Study of Invertebrate Systems we are to understand how locomotor patterns are generated and controlled a necessary step will be to understand how CPG networks produce spatially and temporally coordinated activity. In particular what are the cellular and synaptic mechanisms involved in motor pattern generation?

Studies on the Medial Reticular Formation during Locomotion in Chronic Cats Using Microstimulation ats have now been extended to intact cats chronically implanted with EMG electrodes, and have been supplemented by single unit recordings of identified reticulospinal neurons from the same preparation.

Reticular Formation Stimulation Evokes Walking and Flying in Birds Acute spinalized chicks will also make stepping movements in response to electrical stimulation of the lateral white matter of the transected cervical cord (Jacobson & Hollyday, 1982). Thus the avian spinal cord appears to have the intrinsic neuronal mechanisms necessary for locomotion.

Synaptic Influences Contributing to the Pattern of Limb Motoneuron Activity during Fictive Locomotio exteroceptive stimulations (Perret and Cabelguen, 1980; Cabelguen et al, 1981; Fleshman et al., 1984) and of deafferentation (Perret and Cabelguen, 1976) of the limb. We postulated (see Perret, 1983) that the final pattern of efferent activity during fictive locomotion is elaborated by an output ne
