Veratridine slows down the locomotor rhythm. A1, B2, Locomotor-like activity during bath application of NMA/5-HT (15 μm/5 μm) in both compartments before (A1) and after adding veratridine to rostral lumbar segments (A2). Raw recordings are collected from opposite ventral roots (lL5 and rL5). B1, B2, Locomotor-like activity during the first (B1) and the second (B2) bath application of NMA/5-HT (15 μm/5 μm) in both compartments. The diagrams in A and B illustrate the experimental paradigm. A Vaseline barrier was built at the L2/L3 level to superfuse the most important part of the locomotor CPG independently from the motoneurons recorded from opposite L5 ventral roots.
