From: Decoupling of timescales reveals sparse convergent CPG network in the adult spinal cord
Diverse phase relations during spinal motor patterns. a Experimental setup: Pairwise intracellular recording from the lumbar spinal cord of turtles (medial–ventral horn) during touch–induced scratching. b Histology of a recorded pair of neurons filled with biocytin (red) reveals an IN (Choline Acetyl Transferase (ChAT)–negative, top row) or a MN (ChAT–positive neuron, green, bottom row). Scale bar 50 μm. c Two in–phase neurons during motor activity concurrent with hip–flexor and a knee–extensor synergist (dD8) nerve activity. d Anti–phase MN–IN neuron pair (histology shown in from b). Shaded regions indicate on–phase of the top panel neuron. (e) Phase between pairs indicates wide representation from 0 to 360° (n = 66 pairs). ChAT choline acetyltransferase
