(a) Example of the neural recording from dorsiflexion only at all contacts in Rat 6. The grid corresponds to 7 rings, each consisting of 8 contacts. (b) Plot of a middle ring contact’s neural recording. (c) CAP recorded in all contacts, averaged over 5788 trials. (d) Single detected CAP in all contacts. Recorded signal at all contacts for the dorsiflexion only stimulus, all boxes are from 0–3.33 ms and amplitudes from −20 to 20 μV.
