Figure 7. Total inputs to the L4 and L3 SG neurones from the L1–L6 roots.

Histograms showing the numbers of total inputs observed in the SG neurones located in spinal segments L4 and L3. These histograms include all cells with a monosynaptic input from at least one dorsal root. Neurones were included only if the preparation had all 6 roots undamaged.
