Whisker-box diagrams of absolute and relative synaptic strength of inputs to the HE(8) and HE(12) motor neurons. Data were drawn from a series of 12 preparations in which the input and output temporal pattern of the HE(8) and HE(12) motor neurons was completely specified as illustrated in Figure 6 and in which the strength pattern of the inputs to both motor neurons was also measured, as illustrated in Figure 3. The strength profile across the four inputs, HN(3), HN(4), HN(6), and HN(7) interneurons (standard color code used), is similar to that for the larger population illustrated in Figure 4, indicating that our sample is representative.
