Hochman, S. and B. J. Schmidt. Whole cell recordings of lumbar central pattern generator (CPG) for locomotion (for review, motoneurons during locomotor-like activity in the in vitro neonatal see Gossard and Hultborn 1991). Progress in this area has rat spinal cord. J. Neurophysiol. 79: 743-752, 1998. Whole cell been hampered, in part, by the inherent difficulties of trying current-and voltage-clamp recordings were obtained from lumbar to identify the essential interneuronal components of the
