µCEA interfacing of the fDPN. (A) Schematic of the µCEA designed to interface small nerves (50–300 µm OD). (B) Illustration of the experimental animal setup. The fDPN was placed in the µCEA electrode, and the wire connected to a stimulator box and a computer interface. A catheter in the jugular vein was used to replenish liquids, and cannulation of the carotid artery allowed recording of MAP during fascicular stimulation. (C) Photograph showing the isolation of a single fDPN fascicle (black arrow). (D) Placement of the fDPN (black arrow) in the groove of the µCEA (arrowhead). Scale bar = 1 mm.
